Big 4K Performance

Despite its ultra-compact size, the M310 Plus 4K records in true 4K Ultra HD, capturing finer textures and sharper edges than standard 2K or 3K dash cams. With a 140° wide field of view, it keeps more of the road clearly in frame—without excessive distortion.

Brighter Night Imaging,
Upgraded from the Inside

With a wider f/1.55 aperture than the previous-generation M310 (f/2.0), the M310 Plus 4K captures more light for clearer detail in low-light environments. Combined with 70mai's self-developed algorithm and WDR technology, it enhances contrast, balances exposure, and keeps license plates readable even in complex lighting conditions.

360° Adjustable Lens

Capture from any preferred angle with the 360° manually rotatable lens. The dash cam can also be mounted on the rear windshield for rear recording*, truly versatile.

*For users who currently have a single-camera setup and don't want to switch to a dual-camera system, this product provides a rear recording option. An extension cable may be required to install it on the rear windshield, depending on your car model.

Minimalist Design

With its minimalist, screenless design and ultra-slim body*, this dash cam blends naturally into your car. It stays discreet and stylish while ensuring a clean dashboard and an unobstructed driving view.

*Body size: 92.6 × 43.1 × 46.5 mm

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

24H Smart Parking Surveillance*

When your car is parked, the dash cam automatically records a 30-second video upon detecting a collision, preserving crucial evidence for cases such as insurance claims or dispute resolution—even while you're away.
