70mai S410 Mirror Dash Cam vs 70mai M310 Plus 2K Dash Cam

Buy the 70mai S410 if you want one device covering both directions: it records 2.5K front and 1080P rear, mounts as a rearview mirror with a 9.35-inch touchscreen, and logs GPS. Buy the 70mai M310 Plus if you only need the road ahead: it records 2K at a wider 143° view, has voice control and H.265 encoding, and its 4.9 rating from 150 owners is far stronger than the S410's 4.5 from 13. The S410's rear camera is IP67-rated and its supercapacitor is rated for 500,000 cycles, but its small sample of ratings makes owner feedback less proven.

• Choose the 70mai S410 if you want front and rear coverage in one mirror-mounted unit with a large touchscreen and built-in GPS.
• Choose the 70mai M310 Plus if you only need front recording and want a wider view, voice control and a compact screen-free body.
