Be careful taking Rexing's answer as accurate. Rexing's website under "accessories" has a "Smart Hardwire Kit Mini-USB Port for All Rexing Supercapacitor Models". On this webpage it states that this kit is NOT compatible with the "M2". Also, the manual for the "M2" states that it has BATTERIES at least 6 times. It's also very heavy .... due to batteries. Attached is screenshot capture from the manual.
Sorry, there was a problem. Please try again later.Hi Matt, it indeed is a supercapcitor model. Thanks for bringing it to our attention! As long as the car is off and the camera is hardwired to the cars battery will the parking monitoring function be active. It uses a low voltage draw so there is no need to worry about your car battery or it not working after long periods of inactive time.
