FAQs
How do I enable 24-hour parking surveillance on the 70mai A400?
Parking surveillance requires the optional 70mai Hardwire Kit (UP02), which connects the dash cam to your vehicle’s battery for constant power. Once installed, enable collision detection in the settings via the dash cam screen or 70mai app; the built-in G-sensor will trigger recording on impacts when the car is off.
What type and capacity of microSD card is recommended for the A400?
The A400 supports microSD cards from 16GB to 128GB with a minimum U3 and Class 10 speed rating for reliable high-resolution recording. Use reputable brands like the official 70mai card, Samsung, or SanDisk, and format the card in the dash cam before first use to avoid errors.
How can I achieve 2K QHD resolution recording?
To record in full 2K Quad HD (2560 x 1440), select ‘high compression ratio’ in the video storage settings on the dash cam or via the 70mai app. With ‘low compression ratio’ selected, resolution is limited to 1080P for compatibility and larger file sizes.
How do I view or download footage from the 70mai A400?
Connect your smartphone to the dash cam’s built-in Wi-Fi hotspot, then open the 70mai app for live viewing, playback, downloading videos and photos, or adjusting settings. Emergency recordings are protected in a dedicated folder for easy access.
