Back-up cameras are ideal for RVers. They can be used for checking the traffic directly behind you while you drive or they can help you back into a campsite. Some back-up cameras come in color, while others are only black and white. Many cameras do not have sound, either. These cameras are generally trouble-free, but in a rare occasion when it malfunctions there are a number of ways you can troubleshoot the backup camera yourself.
Check the cable wires if the monitor is not working. At times while you are traveling a plug or cable can disconnect from the camera to the monitor.
Check to see the RV is on. Look to see that the ignition is turned on and the transmission is in the proper gear (reverse).
Look at the position of the camera if you cannot see anything. If the camera is not in the proper position it could be blocked. Check to see that the camera is turned on and that the lens is clean.
Check the volume of the microphone if your camera has sound, but you cannot hear anything. If the volume is at the proper level, check to see that the microphone is clean.
Adjust the controls on the monitor if the color is off or fuzzy. Check to see that the day/night switch is set properly for the time of day.
