How do you keep a wireless backup camera on all the time?
To stay on all the time you can connect 12V to: Running lights, license plate illumination lamp, run line direct to battery, ignition switch or any 12V source on the vehicle. If you want the backup camera to turn on only when you backup then you need to connect the 12V to your vehicle reverse lights.
Where do I tap my backup camera power?
Can you set up a reverse camera to an aftermarket head unit?
It’s possible on some makes and models to fit an aftermarket head unit that can be integrated with the factory reversing camera. We recently installed a Pioneer visual head unit into a Toyota Corolla, and configured the factory reversing camera to work with the Pioneer gear.
