Experience true 4K clarity in an ultra-compact, screenless dash cam designed to stay discreet and out of your line of sight. With enhanced low-light imaging, smart parking protection, and effortless app control, the M310 Plus 4K keeps every drive clearly covered—without the bulk or distraction.
Big 4K Performance：Record in true 4K to preserve finer details such as license plates and road signs. A 140° field of view captures more of the road ahead without excessive distortion.
Clearer Details After Dark：The wide f/1.55 aperture, Super Night Vision, and WDR work together to brighten dark scenes and balance exposure for clearer footage in tunnels, parking areas, and at night.
Compact, Screenless, and Flexible：The compact, screenless body stays discreet and out of your line of sight. Adjust the lens through 360°, while in-app flip and mirror settings keep footage correctly oriented.
Keep Watch While You’re Away：G-sensor collision detection automatically records a 30-second event clip. Time-lapse recording captures continuously at 1 FPS, compressing every 15 minutes into one minute to save storage space.
Capture More Than the Moment of Impact：Buffered Emergency Recording preserves up to 3 minutes 10 seconds before an incident and 30 seconds after, saving the footage in a dedicated Emergency folder for easy access.
Record Without Constant File Management：Loop Recording automatically replaces older standard clips. Emergency and parking videos are saved in separate folders and loop independently, helping protect important footage from regular-file overwriting.
Everything You Need, Right from Your Phone：
Connect through built-in Wi-Fi to preview footage, adjust settings, play back clips, and download videos directly in the 70mai App.
Stay Focused with Voice Control：
Use simple voice commands to control key functions without taking your hands off the wheel.
More Room for Every Journey：
Supports 16GB to 256GB microSD cards, providing more recording space for daily drives, long trips, and high-resolution 4K footage.

Big 4K Performance

True 4K clarity. Zero distractions. Discreetly smart.

Refined Night-Time Imaging & WDR

With a wide f/1.55 aperture, the M310 Plus 4K captures significantly more light than its predecessor, the M310 (F2.0), delivering clearer, more detailed footage in low-light conditions like tunnels and dim parking areas.
70mai's proprietary Super Night Vision algorithm brightens night footage and manages highly reflective white license plates common in Europe and parts of Asia, preserving critical details.
WDR (Wide Dynamic Range) Technology balances exposure, enhances contrast, and improves color accuracy, making license plates easier to read even in challenging lighting conditions.

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* 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 vital evidence is missed.

*The buffer length depends on the collision's timing within the loop recording and the selected loop duration.

24H Parking Surveillance*

While your car is parked, if the G-Sensor detects a collision, the dash cam will automatically trigger a 30-second recording to capture the potential incident. If the relevant video is recorded, the dash cam will notify you with a voice alert once it powers back on.
*The 70mai Hardwire Kit UP03/ UP06 is required.

Time-Lapse Recording

Time-Lapse Recording enables continuous recording at 1 FPS in parking mode. The dash cam compresses every 15 minutes of footage into 1 minute to save memory card space. Faster playback allows you to catch noteworthy incidents instantly.

Compact Design, 360° Flexible Viewing

Designed with a compact, ultra-slim body, the M310 Plus 4K stays discreet and never blocks your view while driving.
Its 360° manually adjustable lens lets you set the viewing angle freely based on your installation and recording needs. Mounted on the front windshield, it can record the road ahead or the cabin; installed on the rear windshield*, it supports rear or interior recording as well—all with a single compact camera.
With in-app video flip and mirror settings, footage remains correctly oriented even when installed upside down.

*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.

Loop Recording

The M310 Plus 4K records in a loop, automatically overwriting older files with the latest recordings, ensuring uninterrupted footage without storage concerns. Rest assured, all critical footage, such as buffered emergency recordings and parking surveillance videos, will be safely saved in separate "Event" and "Parking" folders on the SD card, and will loop independently to prevent being overwritten by regular recordings.

Wi-Fi App Control

Control, view, and download footage effortlessly from your phone via the 70mai app with built-in Wi-Fi.

Voice Control*

Use simple voice commands to operate your dash cam without taking your hands off the wheel.

*Voice commands are currently supported in English and Mandarin only.

Up to 256GB Storage Support

Supports microSD cards up to 256GB, enabling extended recording time for better coverage of your journeys and critical moments.

*We recommend using the 70mai Micro SD Card for Dash Cams to ensure optimal compatibility and stable performance.
