4K video recording. GPS module. Passive safety features LDWS and FCWS. Dynamic noise reduction for night shooting. Parking mode. Remote control from a smartphone.

Vigilant DVR with 4K resolution (3840x2160 pixels) and a remote FullHD reversing camera included. A combination of a wide-angle lens with a 140 ° field of view and an advanced Sony Exmor IMX415 image sensor is responsible for the high-quality video recording on the Xiaomi 70mai Dash Cam A800. As a result, the license plates of passing and oncoming vehicles are perfectly readable, regardless of the time of day and weather conditions outside the car.

A 3-inch screen on the back of the head unit (without touch input support) is used to view the footage "in place" and operate the settings of the car recorder. It is also proposed to remotely “steer” the device from a smartphone via a Wi-Fi network. The built-in GPS determines the current speed of movement and coordinates, tying these data to the video sequence. The model is integrated with the LDWS system, which warns the driver about leaving his lane and reports the risks of a collision (FCWS function). In the parking mode, the DVR itself starts recording when motion is detected in the frame within a radius of several metres. The main power supply of the device is made from the car cigarette lighter socket, the backup is from the engine compartment battery with a capacity of 500 mAh.

Great registrar for the money. Plus, support and the ability to install normal firmware. Writes very well both day and night.
Recording quality, fastening
There are glitches. It is necessary to set the lens to its normal position if the reg is removed at night
Igor Leptugause 70mai Dash Cam A800 few months
Buying from the Chinese is extremely risky, with a high chance of losing money and experiencing stress.
16 October 2021 
I took one, installed the firmware, the recorder died. The seller asked to close the dispute with a guarantee of a free replacement. During the replacement, they charged for the second one. The second one also died after the firmware. I won the dispute, but the return shipping was at my expense at the price of the recorder. The firmware kills the device. Don't buy from the Chinese. Don't expect honest trading from them. And there are no warranties for their products in Russia.
It seems like you're using informal language. A neutral translation could be: "They manage to deceive and trick people."
The device died from the firmware.

The first products under the brand name 70mai, which is the "daughter" of Xiaomi, were released quite recently — in 2017. However, even in such a short time they managed to win the hearts of many motorists. Take, for example, the Dash Cam A800 Dual Channel DVR, an advanced device for 360-degree visibility around the car.

Potential hit

Xiaomi 70mai Dash Cam A800 is a potential bestseller. Judge for yourself, the head unit of the car recorder was armed “to the teeth” with advanced electronic “hardware”, taught to shoot video in 4K, besides, the model is equipped with a remote rear-view camera with FullHD video resolution. The combination of the Sony Exmor IMX415 image sensor and a wide-angle lens with a field of view of about 140 ° is responsible for the quality of recording videos in front of the hood of the “iron horse”. It provides excellent readability of license plates of passing and oncoming cars at any time of the day and in inclement weather. Specially for night shooting, the device has a dynamic noise reduction function.

Advanced hardware

In addition, the head unit of the model has a built-in GPS module (it allows you to link the speed of movement and current coordinates to the video sequence), a Wi-Fi adapter for wireless pairing with smartphones, passive safety functions LDWS (line control) and FCWS (keeping distance). To operate the settings and view the captured videos in the cabin unit, a 3-inch screen is provided (without touch control support).

Backup power

Power is supplied to the DVR from the cigarette lighter socket through a standard adapter with two USB sockets. In case of emergencies, emergency power supply of the device is provided from an on-board rechargeable battery with a capacity of 500 mAh. Video recording is performed cyclically on a microSD flash drive up to 128 GB inclusive. Those. when the space runs out, the camera writes clips over old files. Important frames can be protected from being overwritten in the menu. In the balance, we have a well-charged DVR at an adequate cost.
