The 70mai M310 Plus 3K is a compact front dash cam designed to provide clear evidence of road events. It captures video at a 2880 x 1620 resolution using a Sony IMX307 sensor, which ensures high-quality imagery. To help you see clearly in challenging lighting, the device uses a wide F1.55 aperture combined with WDR and a specialized Super Night Vision algorithm. The 139° viewing angle covers a broad section of the road, while the manually rotatable lens allows you to adjust the perspective to suit your specific windshield layout. This lightweight 70g device connects via USB Type-C and is secured to the glass with double-sided adhesive tape. It manages recordings through the 70mai app via Wi-Fi, supporting loop recording and a time-lapse mode that captures one frame per second. For critical moments, the G-sensor triggers emergency recording, saving a buffer of three minutes before and thirty seconds after an impact. You can store your footage on a MicroSD card up to 256GB, and the system remains operational in temperatures ranging from -20°C to 60°C. While the camera runs on a 300 mAh battery and connects to the cigarette lighter, you can add parking surveillance by using an optional hardwire kit. The black casing blends into the interior, and the inclusion of English voice commands lets you control basic functions without taking your eyes off the road.
