Rexing M2 Smart Mirror Dash Cam with BSD and ADAS

The M2 is a rear-view-mirror dash cam: a 12-inch IPS touchscreen straps over your factory mirror and records 1080p from a front camera and a 1080p rear camera, which also streams a live backup view when you reverse. Blind-spot detection, ADAS, and built-in GPS round out the feature set. No independent community footage comparison for the M2 was located at time of review, so the f/1.6 aperture and 7-element glass lens are spec hypotheses rather than confirmed plate-legibility results. Parking mode is event-based, Auto Event Detection, Time Lapse, or Low Power Mode, and the hardwire kit needed to run it ships in the box, unlike Rexing's V-series. Energy storage is a lithium-ion battery, so it carries no supercapacitor heat-durability advantage in a hot parked car. The glossy 12-inch mirror screen is prone to daytime glare and nighttime headlight reflection.

Best match for drivers who want one device that replaces the rear-view mirror and adds a rear/backup camera, blind-spot detection, and ADAS, the included hardwire kit means parking mode works out of the box. Skip it if you want verified high-resolution footage or hot-climate battery longevity: it records 1080p, not 2K/4K, its footage is unconfirmed by independent comparison, and its lithium-ion battery degrades faster in summer heat than a supercapacitor model like the Rexing V3.

No PPE is required for installation or normal use. The M2 uses a lithium-ion battery; at end of life, drop the unit at a Best Buy or Call2Recycle e-waste point so the battery is handled properly, no manufacturer take-back program is documented. FCC certification covers radio-emissions compliance only; no independent UL or ETL electrical safety listing was found.
