Your Easy Start to Full Protection
Compact yet powerful, with a built-in screen for instant live view, the T400 delivers effortless, full-coverage protection. Capturing front, interior, and rear simultaneously (125°/147°/130°), it expands your field of vision and safeguards your vehicle — whether driving or parked.
Vivid Clarity in Every Scenario
1440P front recording at 30FPS with HDR support delivers clear, smooth and balanced footage, helping keep important road details readable in daylight.

*All videos were shot during driving and have no affiliation or partnership with the brand shown in the footage.
Tailored for Diverse Lifestyles
With automatic infrared switching, it keeps in-cabin recording clear in any light — quietly watching over families at night and supporting taxi and rideshare drivers through every journey.
Buffered Emergency Recording
Accidents happen in a blink—but what leads up to them matters. Our enhanced pre-recording feature captures up to 3 minutes 10 seconds* before and 30 seconds after any incident, ensuring the whole story is preserved. All vital footage is stored in an exclusive "Emergency video" folder, accessible via the 70mai App, ensuring no essential evidence is missed.
*The buffer length depends on the collision's timing within the loop recording and the selected loop duration.
By default, the loop duration is 1 minute, but you can change it to 2 or 3 minutes as needed.
