70mai M800 Dash Cam vs 70mai M310 Plus 2K Dash Cam

The M800 is the stronger camera: 4K front footage, a STARVIS 2 sensor, a real rear camera, built-in GPS and 128GB of internal storage. The M310 Plus is the simpler single-channel option, with 2K video, a 360° rotating lens and a wide f/1.55 aperture, but no GPS and no rear camera. Buy the M800 if you want detailed plates and a two-channel setup; buy the M310 Plus if you want a compact, easy front-only dash cam and don't need GPS.

  • Choose the 70mai M800 if you want 4K detail, a rear camera, built-in GPS and storage included, and you don't mind a larger install.
  • Choose the 70mai M310 Plus if you want a compact front-only dash cam with a rotating lens and a wide aperture for night driving, and GPS isn't important.

Questions and answers

Which is better for night driving?
The M800 has the edge. Its STARVIS 2 IMX678 sensor is built for low light and it records at 4K, so detail holds up better after dark. The M310 Plus has a wide f/1.55 aperture and WDR, which help, but it records at 2K.
Do I need a memory card for either one?
The M800 doesn't; it has 128GB built in. The M310 Plus needs a microSD card from 16GB to 256GB, Class 10 or faster, and none is included.
Which one covers the back of the car?
Only the M800. It ships with a 1080p rear camera using a STARVIS 2 IMX662 sensor. The M310 Plus is front-only.
Is the M310 Plus worth stepping up to the M800?
Step up if you want 4K detail, GPS and rear coverage, which the M310 Plus can't add. Stay with the M310 Plus if a compact front-only camera with a rotating lens is enough.
Which lasts longer?
Both are 70mai units with similar build quality, and the M310 Plus carries a one-year warranty. The M800 avoids card wear because it records to internal storage, while the M310 Plus depends on the card you fit.
Can either record while parked?
Both support buffered recording and motion sensing. The M310 Plus needs an optional UP03, UP06 or OBD kit for 24-hour parking surveillance; the M800 has parking mode built in.
