    One of the reasons I bought this camera was park crash detection. Well, I returned from Las Vegas and my $300 camera did not record my car being hit and the entire front bumper laying on the ground. The only chance I would have to get a license plate number wasn’t even detected. Yeah, if you’re buying this camera for this reason, don’t.

      HI! I am very sorry to hear about your accident.

      Unfortunately, without one of the hardwire kits installed, the camera has no way to detect vibrations or motion.

      Please contact us for assistance on the hardwire kit needed for the add protection of the parking monitor! rexingusa

  • Disappointed in the integrity of Rexing.

    Do not buy this item. Some of these kits have the wires to hook them to the fuse box and some do not. If they don't have the wires, you will have to buy a $30 fuse box wiring kit from Rexing. If you buy the wiring kit to arrive when you buy the camera, then you will have to pay Rexing a $10 restocking fee to return the wiring kit. This is how they "get you". I am highly disappointed in the integrity of the company. I suggest you deal with a better company if you are going to lay out $2XX for a camera.

    This was the second one that I bought. The first one was plug into the cigarette lighter and I dont have one,so I asked for one that would work in a usb port, get home and its a cigarette lighter. I go back to get it installed and they dont do that there. Drive to Florida mall and my 26 colorado ZR2 isn't in the system for installation. I did try calling first,no pickup. So I returned it. I used my GM points and bought my 3rd one, yes they do installation.

    The worst app I have ever had, it will not pair with the dash cam, no matter what I did it would not connect. I do not want to have to take the SD card out every time I want to view videos. Just had this installed yesterday and going tomorrow to make an appointment to have it uninstalled! Shame on you Rexing!!!!!!!!
