Overview
70mai builds the M310 as a front-facing dash cam that records through the windshield and links to a phone over built-in Wi-Fi. A wide-angle lens, WDR processing and a CMOS sensor handle the image, and a microSD card holds the clips.
Control happens from a phone, and voice commands are also listed, so there is no screen to reach for on the dash. Parking monitor, G-sensor and time-lapse modes cover a parked car as well as a drive. Storage is the limit: the card is not in the listed contents, and with no display, framing has to be checked through the app.
Who it's for
A daily driver in a car, SUV, minivan or truck gets a single front recorder with app access to its clips. Parking-mode users can add time-lapse recording. Drivers wanting a rear camera or an on-device screen should look at a different model.
Pros and cons
- Phone app and voice control
- Wide-angle lens with WDR night vision
- Loop recording and G-sensor listed
- Parking monitor and time-lapse modes
- No display on the camera body
- Memory card not listed in the box
- Front camera only, no rear view
- Stated field of view and real angle differ
Performance notes
Image quality depends on the CMOS sensor, the lens aperture and WDR processing, which balances a bright sky against a dark road within one frame. Night footage relies on that same sensor and exposure handling. How much footage is kept depends on card capacity, and loop recording writes over the oldest clips once the card fills.

Frequently asked questions
How should I look after the memory card in the 70mai M310?
The listing calls for a microSD card of Class 10 and above, up to 256 GB, in the single card slot. Loop recording is listed, so the camera records over older clips once the card is full.
Does the 70mai M310 have a screen?
No. Display type is listed as no display, so settings and footage are handled from the mobile app over Wi-Fi.
Is the 70mai M310 a rear or dual dash cam?
No. It is listed as a front camera, sold as a single item, so it does not cover the rear window.
What comes in the box with the 70mai M310?
The listing names a car charger, a charging cable, the dash cam, two electrostatic stickers, one adhesive sticker, a wiring trim tool and a user manual. A memory card is not named.
