Review on Black Universal Backup Camera - Dual Electronics BUCAM200: Enhancing Visibility and Safety by Jessie Zdunich

Very nice picture. This camera offers a lot of features for the price. I didn't give five stars because the installation guide is terrible. Here's what you need to know to install this camera: On your stereo head unit, connect the red wire to the return wire coming from the stereo and connect the yellow RCA connector to the rear camera jack. At the rear of the vehicle, connect the red/black wire labeled "Reverse B+" to the positive wire going to the reverse lights. Connect the black wire to the black wire for the reverse lights. Now connect the red wire coming from the yellow RCA connector to the positive wire going to the reverse lights. So two wires are soldered to the positive pole of the reversing lights. If you connect it this way, you will get a video when you reverse the car. Remember that the positive wire in your reversing light has two functions, one to power the camera and the other to send a signal to the reversing sensor wire so it knows to show video from the reversing camera. If you connect it in any other way, the camera will work all the time, which will shorten its lifespan. There are many bad videos on the internet about this setup. Keep it simple and it will work just fine. You need an extra wire to run the red wire to the negative pole.
