2.4G Wireless Color Video Transmitter and Receiver for Vehicle Backup Camera Front Car Rear View Monitor and Camera System

I'd added a rear camera to my car and did not want the hassle of trying to thread cable from the boot area to the monitor in my centre console. I wasn't too convinced that these would work because of their price, but I get a really good picture on my monitor. The biggest issue I've had with these items is heat. The transmitter in the boot is connected to my reversing lights so it's only on briefly, but my receiver unit was connected to my cigarette lighter socket which was on all the time with the ignition and it did get quite hot. This causes the image to degrade and eventually no image at all. I simply replaced the lighter plug with a switched version so the receiver is now only on when I'm reversing and I get a good clear image. For the money the units do a good job, but they're best only briefly on when in reverse gear.
