Looking for the first dashcam that meets your expectations without compromise? The 70mai M310 Plus 4K is a device designed for drivers who expect professional-quality recordings and effective road protection from the start. Its compact design houses true 4K resolution, intelligent safety features like collision detection, parking monitoring, and night vision recording, and features that are perfect for any driving situation, from daily commutes to long nighttime journeys.

Every detail is crystal clear

The M310 Plus 4K records in full 4K Ultra HD (3840×2160) resolution—each frame retains sharp edges and details that make the difference when recording evidence. The 140° viewing angle covers a wide swath of the road in front of the vehicle without excessive image distortion.

Nighttime is no longer a problem for the camera

The f/1.55 ​​aperture lets in significantly more light than typical f/1.8 or f/2.0 lenses, resulting in brighter and clearer images even in complete darkness. The proprietary Super Night Vision algorithm brightens nighttime footage and copes with the highly reflective white license plates common in Europe. WDR (Wide Dynamic Range) technology evens out exposure, enhances contrast, and improves color accuracy—license plates remain legible even in the most challenging lighting conditions.

Record the entire event, not just the moment

The camera automatically records up to 3 minutes, 10 seconds before and 30 seconds after a detected incident, preserving the full context of each event. Critical recordings are saved to a dedicated emergency folder accessible through the 70mai app and will not be overwritten by the loop.

*The buffer length depends on the timing of the event in the recording loop; the default loop length is 1 minute, with the option to change it to 2 or 3 minutes.

Your car protected 24/7

When your car is parked, the built-in G-sensor detects any impact and automatically triggers a 30-second recording of the event – ​​upon restarting, the camera will notify you with a voice alert. Time-Lapse mode records at 1 FPS (Frames Per Second) in parking mode, compressing 15 minutes of footage into just 1 minute, making it easy to review the recordings instantly.

*To activate parking monitoring, you’ll need the 70mai OBD-II Hardwire Kit (plug-and-play without accessing the fuse box) or the traditional UP03 or UP06 Hardwire Kit, or the 70mai Car Power Bank (all power accessories are available as optional extras).

Small Camera, Wide Mounting Options

The ultra-thin M310 Plus 4K housing doesn’t obstruct your field of view and remains virtually invisible while driving. The 360° manual lens allows you to freely adjust the recording angle: mounted on the windshield, it captures the road or the interior of the cabin, while mounted on the rear window, it captures the view behind the vehicle or passengers. The ultra-thin design ensures maximum comfort of use. This is an ideal solution for owners of single cameras considering rear-view recording.

*Rear-window mounting may require an extension cable, depending on the car model.

Hands-free Recording Management

Loop recording automatically overwrites older files and locks important moments without your intervention. A microSD card supports up to 256 GB, ensuring extended continuous recording time. The 70mai app with built-in Wi-Fi (Wireless Fidelity) allows you to preview and download footage from your smartphone, and voice commands allow you to operate the camera without taking your hands off the wheel.

*Voice commands work when disconnected from the 70Mai app and are available in English and Mandarin.
