Product Features

130° Wide-Angle FOV
The 130° wide-angle field of view allows the dash cam to monitor more lanes with fewer blind spots, providing a broader perspective of the road.

Parking Monitoring & G-Sensor
A built-in G-sensor detects sudden shakes or collisions while your vehicle is parked, automatically initiating recording to capture potential incidents. This provides 24-hour surveillance. A voice alert will notify you when the dash cam is turned back on. Note: The 70mai Hardwire Kit UP03 (sold separately) is required for parking surveillance mode.

Time-lapse Recording
When parked, the M310 can compress 30 minutes of footage into 1 minute, enabling long-term continuous recording at one frame per second. This allows for quick review of hours-long surveillance. Note: The 70mai Hardwire Kit UP03 (sold separately) is required for time-lapse recording.

Loop Recording & Evidence Protection
The dash cam automatically overwrites the oldest footage with the newest to ensure continuous recording. In the event of a collision, the current video is locked to prevent overwriting, safeguarding crucial evidence.

MicroSD Card Compatibility
The dash cam supports microSD cards with capacities ranging from 16GB to 256GB and requires read/write speeds of Class 10 or higher for optimal performance. Lower-class cards may lead to slower write speeds and video recording errors. Note: SD Card is not included.
