All 70mai dash cams conform to the CE certification standard for safety, and has a working temperature range of -10℃～60℃ (14°F~140°F). It is safe to operate our dash cam even in extremely hot weather.

We strongly recommend a 70mai hardwire kit to avoid device incompatibility.

The maximum external storage is 256GB for 70mai Dash Cam A800S.

A800S requires a Micro SD card standard U3&Class 10 or above. You can check if the Micro SD card is eligible by its U3 and Class 10 logo.

You can press the power button once to manually turn off the screen.
You may also change 'Screen off time' in the settings so it automatically turns off after a select period of time.

You may select 'Turn off automatically in parking' in the device's system settings.

This might be due to an old firmware version. Please update firmware manually through the 70mai App to solve this problem.

It is probably that your device's time zone setting doesn't match your turned-on GPS service. Below are two ways to calibrate the time:
1. Find 'time settings' in the 70mai App, and sync the time on your device with the time on your phone.
2. On the device, change the time zone based on your current location, and the time on your device will adjust accordingly.

The working principle of parking surveillance is the sameas recording video in emergency situations.
It uses a gravity sensor (G-sensor) to sense, wake up the dash cam and record video.
Under normal circumstances, it is difficult for a person to shake the car or slam the door forcibly to simulate a large impact or acceleration similar to an accident.
Therefore, it is normal that it doesn’t record an emergency video in a simulation.

The principle is that GPS module-equipped dash cam records longitude and latitude and coordinates speed data regularly during driving.
When you connect your dash cam to the 70mai App, the driving route data will be synchronized to your phone.
You can view the driving route records on the driving route page in 70mai App.

Under time-lapse mode, the dash cam records continuously in 1 frame per second while parking, which plays back at a frame rate of 30FPS.
The benefit of this special recording mode is its lower power consumption and longer recording time.
It occupies only 1/30 of storage space compared to ordinary recording, which is stress-free for long-time recording and adaptive to parking.
