Amkov AMK7000S 4K/1080p 60 FPS Waterproof WiFi Action Camera @ ModSynergy.com
By: Michael Phrakaysone

In 2016, the camera industry experienced a significant surge in technological advancements, particularly in the realm of action cameras. Exciting developments such as dual cameras on smartphones, 3D capabilities, virtual reality (VR), and 360-degree panoramic views became more prominent. Additionally, the emergence of action cameras in various forms, boasting resolutions of 4K and possibly even 6-8K by the end of the year, further intensified the market's appeal.

This surge in innovation also led to a drastic drop in prices over the past 2-5 years, making these cutting-edge technologies more accessible and affordable to consumers. With numerous companies vying for consumers' attention and money, competition served as a driving force behind price reductions and technological advancements.

While GoPro remained the market leader in the action camera segment, their top-of-the-line model came with a hefty price tag of $499 USD. In today's economy, such a price point is simply out of reach for many individuals. Additionally, consumers want to ensure that their investment in an action camera doesn't leave them with a stripped-down product lacking essential features.

Enter the vast array of action cameras produced by relatively unknown companies in the manufacturing powerhouse of China. With over 1.3 billion people in close proximity, it's no surprise that numerous Chinese brands have emerged in this space. However, with such a variety of options available, it becomes challenging to differentiate between decent, good, and downright horrible products. That's why it's essential to rely on reviews to gain insights into what to expect before making a purchase.

Previously, we explored Chinese action cameras like the Zeblaze iShot1 and Amkov AMK5000S, which offered exceptional value by delivering high-end features such as 1080p video recording, rear LCD displays, infrared wristwatches, dual LED flash, WiFi connectivity, and waterproof casings, all at a fraction of the cost of a top-tier GoPro. However, none of these Chinese action cameras proved to be flawless, as they all had their positives and negatives. While they were overall good, they fell short of greatness or excellence. The same assessment can be applied to Polaroid's CUBE lifestyle camera, which benefited from better brand recognition but still had limitations due to its miniature size. Each of these action cameras had room for improvement, but ultimately, the goal is to find a camera that suits your needs while accepting certain drawbacks.

In this review, ModSynergy introduces another offering from Amkov, a higher-end model in their action camera lineup. Previously, we reviewed the lower-end AMK5000S model, which lacked a rear LCD display but delivered 1080p/30fps recording, WiFi capabilities, and a price tag of around $75 USD. It performed admirably for its price range.

Now, our focus shifts to the Amkov AMK7000S action camera, available on Amazon.com for $103.99 USD. This model boasts a rear 2" LCD display, a remote control wristwatch for convenient operation, a 1150mAh battery, a 170-degree wide-angle lens, and expanded resolution options compared to the AMK5000S. These additional resolutions include 240/120fps slow motion, 1080p 60 FPS, 4K, and 2K. On paper, the Amkov AMK7000S appears to be a promising contender, but how does it fare in real-world usage? Read on to discover the answer!

First Impressions

The packaging of the Amkov AMK7000S is similar to its predecessor, the AMK5000S, and this is a positive aspect as the AMK5000S had one of the better-designed packages seen in a while. The camera comes in a compact corrugated cardboard interior with an outer slip-on layer that effectively conveys the "action" theme, featuring a photo of a water surfer on the package.

One improvement from the AMK5000S box is the inclusion of the Amkov brand name on the AMK7000S packaging. This addresses the absence of the brand name in the previous model, which was mentioned in my previous review. The package also features a window that showcases the action camera inside its waterproof case. Various symbols indicating 4K, WiFi Sports Cam, 60FPS, and 1080p HD, along with product images displaying the camera in different configurations, adorn the box.

Turning to the rear of the box, you'll find a comprehensive breakdown of specifications and a visual representation of all the accessories included with the camera. The side of the box contains two QR codes that, when scanned, allow customers to download the AMKOV WiFi app for Android or Apple devices.

Now, let's take a look at the list of items included in the package:

• Amkov AMK7000S Action Camera
• Users Manual
• Vertical Quick Release Buckle
• Curved Mount with 3M Adhesive
• Flat Mount with 3M Adhesive
• Tripod Mount
• 3-Way Pivot Arm Mount
• Plastic Protective Cover (For use outside of waterproof housing)
• Thumb Screw
• Wrist Band Mount
• Cable Ties

It's worth noting that despite being a higher-end and costlier model, the Amkov AMK7000S does not include a secondary vented back cover for the waterproof case and a micro USB wall charger adapter, both of which were provided with the lower-end and less expensive AMK5000S. This omission may be attributed to the inclusion of the infrared remote control wristwatch in the AMK7000S package, as Amkov may have made the decision not to bundle these additional items.

Nevertheless, the Amkov AMK7000S does come with a sufficient number of accessories to get started. Moreover, since it utilizes the GoPro mounting system, which is widely accessible and interchangeable, users should have no trouble finding a wide range of additional accessories to purchase in the future. The bundled accessories that come with the AMK7000S exhibit good quality and durability, giving the impression that they can withstand extended use and abuse.

As for the user manual, it is translated into multiple languages and provides comprehensive coverage of all aspects of the camera. It is straightforward, well-organized, and includes symbols, diagrams, and tables to facilitate understanding and ease of use.

Visual Overview

The Amkov AMK7000S adopts a design that closely resembles the conventional action camera form factor, bearing a striking resemblance to the GoPro Hero 4. While the design is functional and familiar, it would have been interesting if Amkov had chosen to differentiate their camera with a unique design element, similar to what Zeblaze did with the iShot1 by incorporating a front aluminum alloy faceplate and two LED front flashlights, setting it apart from other cameras in the market.

The Amkov AMK7000S is available in three different colors: yellow, black, or silver. However, these color variations are limited to the faceplate, while the rest of the body maintains a black color. The exterior body features a smooth, tactile finish, providing a comfortable grip. In all three color options, the lens ring remains black. This addresses a concern I had with the AMK5000S, where the mismatched color between the lens ring and faceplate made the lens ring stand out and compromised the camera's discreet appearance. Thankfully, this time around, the black lens ring blends more seamlessly with the overall design, eliminating the visual distraction that a silver lens ring would have caused.

Surprisingly, the Amkov AMK7000S is slightly smaller and lighter than its predecessor, the AMK5000S, by approximately 2-4 grams, depending on the specific configuration. This is unexpected considering the AMK7000S features the addition of a rear 2.0" LCD display, which was not present in the AMK5000S. The weight reduction is a welcomed improvement, enhancing the camera's portability and ease of use.

The Amkov AMK7000S has compact dimensions, measuring approximately 2.32" x 1.61" x 0.82". Without the battery, it weighs 53 grams (0.116 lbs), which is 2 grams lighter than its predecessor, the AMK5000S. With the battery included, the weight increases to 76 grams (0.168 lbs). When placed inside the clear waterproof housing and equipped with a quick release buckle and thumbscrew, the total weight amounts to 162 grams (0.357 lbs), making it 4 grams lighter than the AMK5000S in the same configuration.

Constructed primarily with plastic materials, the AMK7000S may not possess the sturdiest or most robust build compared to other cameras on the market. However, it is still capable of fulfilling its intended functions effectively. When using the camera inside the provided waterproof case, any potential impacts or shocks will be adequately absorbed, ensuring the camera's protection during extreme activities.

It's important to note that the rear 2" LCD display is covered with a thin plastic film. Therefore, it's crucial to avoid touching or applying pressure to the rear LCD screen, even with light force, as it may result in the appearance of waves and ripples or even cause damage. Since the AMK7000S does not have a touch screen interface, there is no need to touch the display. The same precaution applies to the front LCD panel, which is best left untouched.

While the Amkov AMK7000S can be used without the waterproof housing, it is important to note that it should be kept away from extreme weather conditions and potential impacts to ensure its durability. However, once placed inside the waterproof housing, any concerns about durability are addressed.

The waterproof housing of the AMK7000S is designed to withstand water pressure up to 40 meters, which is 10 meters deeper than its predecessor, the AMK5000S. The housing is exceptionally thick and sturdy, leading to speculation that it may be constructed from Polycarbonate due to its robustness. It comes with a sealed back door, although it lacks the additional vented back door included with the AMK5000S. Consequently, audio quality inside the waterproof case is compromised. The back door is secured by a white silicone o-ring and a locking mechanism that requires considerable force to open and close, ensuring a watertight seal. The housing allows full access to all three buttons, ensuring complete functionality.

One notable improvement in the AMK7000S design is the battery compartment door, which differs significantly from the AMK5000S. The previous issues with rattling and difficulty in opening and closing the door have been resolved with the updated battery chamber and locking mechanism. Additionally, the AMK7000S uses a different type of Lithium-Ion battery.

At the front of the camera, attention is drawn to the 170° ultra wide-angle lens surrounded by a black lens ring. It is worth mentioning that, similar to the AMK5000S, the lens ring color does not match the faceplate color. This inconsistency may be due to manufacturing processes, as repainting the lens unit for each color variant might not be practical.

A monochromatic dot-matrix LCD display is situated to the left of the lens, above the mode button, serving as the front menu screen. It provides information on the current mode, recording length, photo capture details, power status, and battery life. The display cycles between video and photo mode information since the addition of the 2" rear LCD display focuses on other functions of the AMK7000S. The rear LCD is a TFT 260K Color unit with a resolution of 240 x 320. While it may not offer the most impressive display quality, considering its size, it performs adequately. Viewing angles are fair, but the colors may appear distorted and the brightness reduced when viewed off-center due to the properties of TFT LCD screens. The display's 260K colors may not provide true color rendition, but it is well-suited for the camera's purpose. The inclusion of the LCD screen greatly enhances the user experience, eliminating the need to rely solely on the Amkov-iCam application on a smartphone or tablet for changing settings. It offers a more intuitive and convenient way to adjust settings directly on the camera.

However, the user interface (UI) could have been more user-friendly. Navigating the menu takes longer than necessary, especially for first-time users who may find it confusing. Accessing in-camera settings requires pressing and holding the WiFi button for 3 seconds, while navigating through the menu involves repeatedly pressing the WiFi button to scroll. This process can be tedious, leading to inadvertently missing desired options and having to cycle through the entire menu repeatedly. To access the system settings, the front mode button is used, and the shutter button is used to enter and select options. The labeling at the bottom of the UI, indicating "OK - Enter" and "MENU - Back," is incorrect.

To the right of the mode button, two LED lights are present: a blue charge indicator light and a green LED activity light. The green light indicates activity when connected to a computer for file transfer and during video recording. Additionally, a red WiFi symbol and the Amkov company logo adorn the front faceplate. Behind the Amkov logo lies the infrared (IR) receiver, facilitating communication with the remote control wristwatch.

Unfortunately, upon closer inspection, the red WiFi symbol on the front of the camera may appear sloppily painted. It seems that the symbol was applied using a template, and when the template was removed, it resulted in paint spray marks on the silver faceplate. While this may be seen as a minor imperfection, it does not significantly impact the camera's functionality.

At the top of the AMK7000S, there is a distinctive diamond pattern that runs along the entire profile of the camera. Multiple holes are present for the microphone and general ventilation purposes, providing passive cooling. Positioned to the right is the shutter button, used for capturing photos or recording videos. Just above the shutter button, there is another LED indicator light that blinks during video recording or photo capture.

While the overall fit and finish of the camera are satisfactory, there is a slight issue with the functionality of the shutter button. It appears that the button doesn't work optimally when pressed towards the backside, closer to the rear LCD display. It lacks a solid click feeling and may not register the command effectively. However, when pressed on the topside of the button, the click feeling is more pronounced, and there are no issues with responsiveness. This specific issue was not observed with the AMK5000S. It is worth noting that this could be a problem specific to the review sample, and other units may not exhibit the same behavior.

At the bottom of the AMK7000S, there are additional holes that serve a dual purpose. These holes allow the microphone to capture audio effectively while also providing passive cooling for the camera.

Located at the bottom is the battery compartment door, indicated by the words "Li-ion Battery." The door is designed to slide in and out, allowing for easy opening and closing. It is equipped with a spring-loaded mechanism to ensure secure closure and proper contact with the battery.

On the right side of the camera, the words "FHD 1080P" are embossed on the plastic body, indicating the camera's video resolution. In the middle of the side, there is another LED indicator light, while below it, the WiFi symbol button is located. Pressing the WiFi button once activates the internal WiFi, and the LED screen displays the SSID and password for connection. Once connected, the screen displays the name of the connected device. The LED on this side specifically indicates WiFi operation and blinks during its functioning.

The rear 2.0" LCD display is surrounded by a black bezel that includes the words "sports-cam," "1080P-60fps," and a WiFi symbol. However, it's worth noting that the rear plastic screen bezel is not perfectly aligned with the LCD display, resulting in a slight portion of the display being cut off. For example, when looking straight at the screen, the battery status indicator symbol and video recording symbol on the left side may be partially obscured. However, if you tilt the camera and view it from an angle, you can see the complete symbols. While this offset is not a significant issue, it is interesting to note.

In terms of the LCD panel uniformity, there are no issues such as clouding or backlight bleeding, indicating the use of a good-quality panel in this camera.

To the left of the LCD display, there is a small dot that may initially be mistaken for an ambient light sensor, but it is actually another LED activity light, similar to the ones found in other parts of the AMK7000S.

This area at the back of the camera is where all the action happens, including framing your shot and making on-the-fly changes to in-camera settings. The ability to frame your shot is a significant feature that was sorely missed in the AMK5000S and other action cameras without a display. The rear bezel is made of a glossy yet thin plastic film, so it's important not to touch the LCD display directly to avoid causing waves, ripples, or potential damage. In terms of LCD brightness, it performs adequately but may not be the best under very bright and sunny conditions. You may still need to shield the LCD from direct sunlight, but overall, it performs well and is highly usable and useful.

Moving to the left side of the camera, we find yet another LED activity light, a micro USB charge port, a micro HDMI output jack (cable not included), and another micro USB charge port. If you've been counting, there are a total of four LED activity lights dispersed throughout the action camera.

In contrast to the lower-end AMK5000S, the AMK7000S addresses the absence of audible tones by incorporating this feature based on user feedback. This addition proves beneficial as it allows users to receive audio cues for various camera functions and settings. When powering on, shutting off, or navigating through modes and menus, the camera emits audible beep tones to indicate these actions. This enhancement significantly improves the user experience, particularly in real-world scenarios and outdoor settings where it may be inconvenient or impractical to constantly check the camera's visual indicators. With the audible tones, users can rely on the audio cues to stay informed about the camera's status without needing to visually confirm each operation.

The Amkov AMK7000S - Is It Any Good?

The firmware version included in the box of the AMK7000S was 1.02. Unfortunately, I encountered freezing issues right from the start, even without a micro SD card inserted. To resolve this, I visited Amkov's website and Facebook page and discovered a newer firmware version, 1.03. Updating to this version fixed the freezing problem. Since then, Amkov has released another firmware upgrade, bringing it to version 1.04.

While it's commendable that Amkov is responsive to customer feedback and actively addressing issues, the frequent release of firmware updates raises concerns about the camera's initial stability. Ideally, the AMK7000S should have been released with a stable firmware after thorough testing to ensure a smooth user experience. It feels as though customers are being used as beta testers for the product.

Interestingly, the AMK7000S prominently displays "FHD 1080P" on its body, which is odd considering its marketing as a 4K camera. 4K resolution, technically 4096 x 2160, is highly sought after, especially with the growing popularity of Ultra HD 4K and affordable 4K HDTVs. However, the AMK7000S can only achieve 4K resolution at 10 frames per second and 2.7K resolution at 15 frames per second. In practical terms, this makes 4K and 2.7K modes largely unusable, turning the camera into a 1080p/60 FPS action camera. While 1080p is still a popular and functional resolution, it's disappointing that the advertised 4K and 2.7K capabilities fall short.

The discrepancy in frame rates between the AMK7000S and the more expensive GoPro HERO4 Black can be attributed to the superior DSP and image sensor combination used by GoPro. The Ambarella A9 SOC solution employed in the HERO4 Black enables it to achieve 4K at 30/24 FPS and 2.7K at up to 60 FPS, justifying the higher price tag.

In terms of hardware, the AMK7000S shares a similar setup with its predecessor, the AMK5000S. Both cameras utilize the OmniVision OV4689 CMOS 4-MP image sensor. However, the AMK7000S is paired with a higher-spec Sunplus 6350M DSP, enabling 1080p at up to 60 FPS and 720p at up to 120 FPS for slow-motion recording. It's important to note that the AMK7000S wasn't specifically designed for 2.7K and 4K, as the image sensor doesn't natively support these resolutions. Consequently, the 4K and 2.7K modes on the AMK7000S are likely achieved through software interpolation rather than being true native resolutions. It would have been more transparent if this information was disclosed to customers upfront.

One of the standout features of the AMK7000S is its ability to record at 1080p/60 FPS and 720p/120 FPS for slow-motion videos. These additions, along with the marketed 4K and 2.7K capabilities, make it the first action camera in my testing with such recording rates. The advantage of 60 FPS is particularly useful for capturing fast-moving subjects without motion blur, such as in hockey games or footage from a drone. In summary, while the AMK7000S has firmware updates to address initial issues, its limitations in achieving true 4K and 2.7K resolutions, as well as the disparity in frame rates compared to higher-end cameras like the GoPro HERO4 Black, may disappoint some users. Nevertheless, the camera 's added capability of 1080p/60 FPS and 720p/120 FPS recording, along with stable performance after firmware updates, can still make it a viable option for capturing high-quality action footage.

Amkov Infrared Remote Control Wrist Watch

Amkov includes a remote control wristwatch with the AMK7000S, allowing you to conveniently trigger video recording and photo capture with a single touch from your wrist. The watch utilizes infrared (IR) technology, unlike the 2.4GHz watch that came with the Zeblaze iShot1. While IR has limitations in terms of distance and sensitivity compared to 2.4GHz, this shouldn't be a major issue since action cameras are typically used in close proximity.

One drawback of IR technology, similar to a TV remote control, is its directional nature. The IR transmitter on the watch needs to be pointed directly at the camera's IR receiver for the command to register. If you point the watch behind the camera, you need to be in close proximity for the signal to reach the receiver. Additionally, IR requires line of sight, so it won't work if there are obstacles like walls or bookshelves in the way. However, these limitations are unlikely to pose a problem in the context of using the watch with an action camera. On the positive side, no pairing or setup is required, allowing you to use the watch right away.

Amkov has implemented their remote control wristwatch much better than Zeblaze did with theirs, addressing issues such as illogical key mapping and operation. The Amkov watch offers straightforward and foolproof operation without any setup hassles. It's not a gimmick, and Zeblaze could learn from Amkov's approach.

The wristwatch itself is simple in design, featuring a Velcro strap and two bright orange buttons. When a button is pressed, a red LED lights up to indicate the action. One button is designated with a camera symbol for switching to photo mode, while the other button has a video record symbol for switching to video recording mode. These universal symbols make the functions easy to understand for most users.

It's important to note that the wristwatch cannot power the camera on or off. The camera must be powered on for the watch to function. Once the AMK7000S is powered on, using the wristwatch is as follows:

1. Pressing the camera symbol button once switches the camera to photo mode.

2. Pressing it again captures a photo. Pressing the video record symbol button once switches the camera to video recording mode. Pressing it again starts the recording, and pressing it again stops the recording.

Amkov AMK7000S Software - AMKOV-ICAM WiFi App

The Amkov-icam WiFi app is available for both Apple devices on the Apple App Store and Android devices on the Google Play Store. Although the app has some common issues found in Chinese action camera applications, such as lack of intuitiveness and occasional crashes, it has shown improvement over time with updates.

To establish a wireless connection with the AMK7000S, follow these simple steps, which should take less than a minute for the initial setup and less than 15 seconds for subsequent attempts:

1. Use the QR code provided on the side of the box to download the Amkov-icam app on your smartphone or tablet device.

2. Press the WiFi button on the right side of the AMK7000S action camera once to enable WiFi. The LED indicator light will blink green until a connection is established and then remain solid green.

3. The action camera will display the SSID and password on the rear LCD. On your Android or Apple device, navigate to the wireless settings and connect to the SSID "iDV4_A6C65CA5." Enter the default password "1234567890." You are now connected.

4. Launch the Amkov-icam app on your smartphone or tablet device. The app will establish a wireless connection with the action camera, and you will see a live video feed.

With the Amkov-icam app, you can use your smartphone or tablet device to:

- Record videos

- Capture still photos

- Create time-lapse videos

- Adjust in-camera settings

- View videos and photos on the AMK7000S via WiFi playback mode

- Download videos and photos from the AMK7000S to your device

The WiFi live feed performance of the AMK7000S is similar to the AMK5000S since it features a higher-spec chipset. The WiFi delay lag is virtually non-existent when the camera is close to the connected device. This is a notable achievement compared to the Zeblaze iShot1, which had a noticeable 1-2 second delay. However, as expected, increasing the distance between the camera and the WiFi-enabled device will result in increased delays, as this is inherent to WiFi technology.

Although the Amkov-icam app has improved in terms of stability, occasional bugs and crashes still occur. Some menu options could benefit from better English descriptions. For a more detailed account of issues and problems with the app, it is recommended to refer to the review of the Amkov AMK5000S action camera and its WiFi app section. However, the AMK7000S has shown better WiFi stability compared to the AMK5000S.

It's worth noting that when using the app's WiFi function, the resolutions of 4K and 2K are not available and not even listed. This limitation may be due to the camera's inability to support the latest WiFi standards and stream high-resolution video feeds on the fly, as 4K and 2.7K files are large in size.

Picture Quality

The Amkov AMK7000S, compared to its predecessor, the AMK5000S, exhibits a regression in still photo quality. The photos, particularly the interpolated ones, appear worse, and there seems to be a significant change in the photo style. Both cameras use identical image sensors and similar chipsets, so the most likely cause for this decline in picture quality is a firmware-related issue or lack of optimizations. The lens is not the culprit, as it has actually improved, as discussed in the Video Quality section.

Amkov advertises that the AMK7000S can capture 20-megapixel still photos, but this value is highly exaggerated and far from the true native resolution of the OmniVision OV4689 image sensor, which is only 4 megapixels. It is advised to capture still photos at the 4 MP resolution, which is the camera's native resolution and provides more realistic and better-quality results compared to any interpolated resolution photos. The higher the interpolation, the worse the image quality, as evidenced by the samples provided.

Interestingly, in the previous AMK5000S review, there was no 4-megapixel photo resolution option available despite it being the native resolution. Fortunately, the AMK7000S now offers this option.

Overall, the quality of still photo captures, particularly at interpolated resolutions, is inferior to that of the AMK5000S. The interpolated photos from the AMK5000S appeared fairly realistic, while the interpolated photos from the AMK7000S have a different and somewhat artistic pastel painting-like appearance. It is unclear how this change occurred, but it may be attributed to a different interpolated algorithm used in the AMK7000S. It would have been better if they had stuck with the same interpolated algorithm from the AMK5000S, as this regression is a step backward.

For optimal results, it is recommended to either a) capture still photos on the AMK7000S at 4 MP resolution or b) record videos and extract still frames from the footage.

Choosing any resolution above 4 megapixels for photo capture will result in software interpolation, artificially enlarging the image and introducing strange pixels, blockiness, excessive sharpening, and aggressive artifacts that make the photos appear distorted, almost like pastel art paintings. It is advised to avoid using interpolated photo resolutions.

Additionally, it is worth noting that the field of view (FOV) becomes narrower in photo capture mode compared to video recording mode. Therefore, the fish-eye effect is less pronounced in photos than in videos.

One issue experienced with the AMK5000S was a tendency to be prone to lens flares in bright and sunny conditions, resulting in halos, red spots/circles, and slight chromatic aberrations in photos and videos. This was attributed to the lens unit on the camera. However, the AMK7000S shows significant improvement in handling lens flares and sun glare, demonstrating overall enhancement in this aspect.

Video Quality

The AMK7000S exhibits advancements in video quality compared to its predecessor, the AMK5000S, despite sharing the same image sensor. The integration of a higher-spec Sunplus 6350M chipset and an upgraded lens unit contributes to this improvement.

Equipped with OmniVision's 4-megapixel OV4689 CMOS sensor and the Sunplus 6350M chipset, the AMK7000S offers video recording in H.264 MPEG-4 AVC format, supporting various resolutions and frame rates. Notably, the inclusion of 60 frames per second (FPS) recording and firmware optimizations contribute significantly to the enhanced video quality.

In terms of video container formats, the AMK7000S primarily records in the widely compatible MP4 format, except for 4K and 2.7K resolutions which are recorded in MOV format, although the reasoning behind this discrepancy remains unclear.

It is important to note that the 4K and 2.7K resolutions on the AMK7000S are achieved through interpolation, as the native resolution of the OV4689 sensor does not reach these levels. Consequently, the image quality at these interpolated resolutions may exhibit some artifacts and limitations. Nevertheless, upon closer examination, the sharpest image is observed at around 2.7K resolution, despite the interpolation.

The AMK7000S offers a variable bitrate for video encoding, resulting in superior footage compared to other tested action cameras. The bitrate ranges from 28.3 to 38.5 Mbps for 1080p/60 FPS, and 49.1 to 56.7 Mbps for 4K/10 FPS and 2.7K/15 FPS. It is important to consider the larger file sizes associated with higher bitrates, which necessitate a larger micro SD card for adequate storage capacity.

In terms of image characteristics, the AMK7000S exhibits improved sharpness, color rendition, and motion compared to its predecessor, the AMK5000S. The lens unit is notably sharper and handles lens flares more effectively, while color reproduction appears slightly more vibrant. However, it is worth noting that color accuracy is not flawless, and the automatic white balance tends to lean towards a colder color cast.

The dynamic range of the AMK7000S remains similar to that of the AMK5000S, with no discernible difference in contrast or blown highlights. While low light footage is average, it displays fewer artifacts and grains compared to other Chinese action cameras. Although lacking an HDR mode, the AMK7000S performs reasonably well in low light conditions, thanks in part to its support for higher variable bitrates.

The AMK7000S offers stabilization and a low light mode as additional features, but their impact on video quality is minimal. The effectiveness of the stabilization feature is questionable, and the low light mode does not yield a significant improvement in video quality.

Regrettably, the AMK7000S lacks a file looping option, making it less suitable for use as a car dashcam. Additionally, it does not feature an instant record feature upon startup. These are areas where improvements could be made to enhance the camera's usability.

In conclusion, the AMK7000S demonstrates noticeable enhancements in video quality compared to the AMK5000S, thanks to its higher-spec chipset, firmware optimizations, and improved lens unit. However, there is still room for further refinement, such as additional customization options and improvements in stabilization and low light performance. Including features for adjusting sharpness, contrast, brightness, and custom Kelvin temperatures in the camera's settings menu would make the camera a better product overall.

Sound Quality

Unfortunately, the audio quality of the Amkov AMK7000S has taken a step backward compared to its predecessor, the AMK5000S. This is disappointing considering the potential of the AMK7000S as a great product overall.

The audio recording on the AMK5000S was exceptional, characterized by a balanced mix of low-end fullness and high-end crispness. It provided a realistic sound experience, with audio levels set higher than usual, resulting in loud playback during video viewing – a desirable feature.

However, the AMK7000S fails to match its predecessor's audio performance. The audio gain is significantly weaker, resulting in lower volume and poor sound pickup, even when used without the waterproof casing. In comparison to the rich audio produced by the AMK5000S, the AMK7000S sounds thin and lacking in fullness. The focus is mainly on high-frequency treble, while the low-frequency tones are virtually absent. It is truly unfortunate that the audio quality of the AMK7000S is far from the pleasing output achieved by the AMK5000S.

The regression in audio quality begs the question of what Amkov was thinking during the development process. It seems illogical to take a step back in such a crucial aspect of the product.

To understand the root cause of the audio quality regression, a significant change in the audio codec used by Amkov becomes apparent. The AMK5000S employed an uncompressed lossless 44,000 kHz 16-bit PCM audio codec with a bitrate ranging from 700 to 850 kbps for 1080p/30 FPS video. This uncompressed audio codec and the healthy bitrate range contributed to the superior audio experience provided by the AMK5000S, especially in the context of an action camera.

However, the AMK7000S takes a different direction by adopting the AAC audio codec, which is a lossy format and inherently compressed. This shift alone is a major reason behind the noticeable decline in audio quality. The AMK7000S utilizes a 48,000 kHz MPEG AAC audio codec with a bitrate ranging from 127 to 148 kbps (observed at 1080p), significantly deviating from the audio specifications of its smaller brother, the AMK5000S.

This sudden change to a compressed audio format with lower bitrate is indeed concerning and contributes to the disappointing audio quality experienced with the AMK7000S.

Is It Waterproof?

I didn't have a definitive method to verify the waterproof case's capability of reaching 40 meters, but I decided to put it to the test by submerging it in a swimming pool. In an upcoming review, I will be evaluating an accessory that facilitated capturing underwater footage, and I plan to use the submerged video footage for that particular review. If necessary, I will also update this review later on with the same footage.

I'm pleased to report that the AMK7000S waterproof case performed admirably during the test, as no water managed to seep inside the action camera. It passed the underwater trial without any issues, providing me with confidence in its waterproofing abilities.

I found that the locking mechanism of the AMK7000S is just as secure as the one on the AMK5000S waterproof case. The seal surrounding the housing door is thick, and the locking latch mechanism requires a substantial amount of force to open and close, ensuring a watertight seal. Based on my assessment, I believe you shouldn't encounter any water-related problems as long as the camera remains inside the waterproof housing.

Edit: Included below is the footage from my waterproof testing of the Amkov AMK7000S. It showcases the camera inside the waterproof case during a swimming session.

Battery Life

The AMK7000S is equipped with a 1150mAh capacity Lithium-Ion battery. One notable feature of this camera is its smart charging circuit, which ensures that the camera charges slowly and correctly regardless of the USB charge adapter used. I tested the camera with various USB charge adapters, ranging from 500mA to 2000mA, and consistently observed a gradual charging process. The charge started at 0.40A and gradually decreased to 0.3mA for a significant duration, further reducing the charging rate as it approached completion. This indicates a well-designed charging circuit that prevents overcharging, ultimately benefiting the battery's lifespan and recording times.

During my initial charging of the AMK7000S from a depleted state, it only reached a capacity of 876mAh according to my USB charge doctor device. A full charge typically took around 3 hours and 30 minutes to complete. Subsequent charges showed a gradual increase in battery capacity, with the highest reading reaching 937mAh. However, it is worth noting that the battery falls short of its advertised 1150mAh capacity. It's possible that the specific battery used for this review may not meet the expected performance, so individual experiences may vary.

Amkov claims that the AMK7000S can record up to 2.5 hours, but the specific conditions for this claim are not provided. It is likely that the camera was tested with the LCD off and at 1080p resolution rather than higher resolutions. We will soon find out if this assumption holds true.

For comparison purposes, the Amkov AMK5000S (which lacks a rear LCD) and Zeblaze iShot1 action cameras achieved a runtime of approximately 2 hours and 3 minutes to 2 hours and 5 minutes when recording at 1080p/30 FPS before their batteries depleted.

Since I do not consider the (interpolated) 4K and 2.7K resolutions on the AMK7000S as usable due to their low frame rates of 10 FPS and 15 FPS respectively, I opted to conduct battery runtime testing at the highest native resolution, which is 1080p/60 FPS.

With the LCD display turned on throughout the entire recording at 1080p/60 FPS, the AMK7000S provided a battery life of 1 hour and 25 minutes before the battery completely drained and the camera shut down.

With the LCD display turned off after 1 minute of recording and remaining off for the duration of the test at 1080p/60 FPS, the AMK7000S offered a battery life of 1 hour and 38 minutes before powering down. Interestingly, there was not a significant difference in battery life with the LCD display off. Therefore, the AMK7000S falls short of the claimed 2.5-hour battery runtime at 1080p/60 FPS and does not match the 2-hour runtime achieved by both the Amkov AMK5000S and Zeblaze iShot1.

It is possible that the battery being tested in this review may not be representative of the expected performance. As mentioned earlier, the rated 1150mAh battery only demonstrated an actual capacity of 937mAh according to my USB charge doctor device, falling approximately 237mAh short of the claimed 1150mAh.

Edit: In response to Amkov's request, I conducted the same test at 1080p/30 FPS with the LCD off (set to power down after 1 minute). The AMK7000S lasted for a total of 2 hours before the battery was completely depleted. At this resolution, the battery life is comparable to the AMK5000S (without a rear LCD) and the Zeblaze iShot 1 (with a rear LCD) that I previously tested. However, it still falls short of the manufacturer's claimed 2.5-hour battery runtime.

Conclusion

The Amkov AMK7000S offers excellent value in the action camera market, especially considering its price below $105 USD. It boasts a wide range of recording resolutions, including 4K and 2.7K (interpolated), 1080p at 60/30 FPS, and 720p at 120/60/30, along with slow motion and time lapse capabilities. The inclusion of WiFi connectivity, a convenient remote control wristwatch, and a 2.0" LCD screen on the rear enhance its usability and intuitiveness. Overall, the video performance of the AMK7000S surpasses that of its smaller sibling, the AMK5000S.

However, the audio recording performance of the AMK7000S falls short compared to the AMK5000S, which is disappointing. Amkov made the wrong choice by switching from uncompressed PCM audio with a higher bitrate in the AMK5000S to compressed AAC format with a lower bitrate, resulting in a significant decline in audio quality. The audio gain is also inferior on the AMK7000S, lacking the fullness and realism found in the AMK5000S. This disparity between excellent video performance and subpar audio is a significant mistake on Amkov's part.

In terms of user interface, the AMK7000S could have been more user-friendly. With only three buttons and no dedicated up and down button, navigating the menus can be confusing, often leading to accidental skipping of desired options. This can be time-consuming, requiring users to cycle through the entire menu again. While manageable, it could have been simplified with a more intuitive design.

Battery performance, at least on my review unit, also regressed compared to the claimed figures. The AMK7000S was unable to reach the advertised 2.5-hour battery life or match the 2-hour runtime achieved by the AMK5000S, even with the LCD turned off for most of the test. This test was conducted at 1080p/60 FPS. However, when tested at 1080p/30 FPS with the LCD off, the AMK7000S lasted 2 hours, which is comparable to the AMK5000S and Zeblaze iShot1. Still, it fell short of the manufacturer's claimed battery runtime. It's worth noting that the tested battery came up 237mAh short of its rated 1150mAh capacity, and individual experiences may vary. A better battery could potentially yield better results.

Additional minor negatives include the exclusion of the ventilated back cover for the waterproof case and USB charge adapter, which were bundled with the AMK5000S.

Overall, the Amkov AMK7000S is a recommendation-worthy action camera, primarily due to its improved video performance. However, the disappointing audio quality, along with other drawbacks, should be taken into consideration. It falls short of being great due to the audio performance. Ultimately, your decision should depend on how you weigh these drawbacks and what aspects you prioritize.
