Rexing M2 Smart BSD ADAS Dual Mirror Dash Cam Review

You do not need a second monitor in your car, but you do need a way to see what is happening behind you without turning your head into a traffic hazard. The Rexing M2 Smart BSD ADAS Dual replaces your standard rearview mirror with a 12-inch IPS touchscreen that streams live video from both the front and rear cameras. It is not just a recorder; it is a safety interface that layers Blind Spot Detection (BSD) and Advanced Driver Assistance System (ADAS) alerts directly onto the mirror view. If you are tired of fumbling with a small, dim dash cam screen while trying to merge, this setup puts the critical data right in your line of sight. The dual-channel recording ensures that if you are rear-ended, you have the footage to prove it, while the mirror form factor keeps your windshield clear.
