This matches our 5 inch heavy duty monitor with a CCD bullet style reversing camera. The monitor has a separate wireless receiver and an optional extension cable can be selected if you need to move it to a more suitable location. The bullet camera fits a 28mm hole and is best mounted pointing down to avoid getting too much sky in the image. If you do get a lot of sky it does tend to dull the lower half the image. This camera takes its power off the transmitter box which although waterproof we feel it is best kept internal as a precaution and to avoid stone dame to the aerial. There is the option to add an extension cable if needed.
