This matches a 7 inch clip over mirror mount monitor with with our CCD bullet reversing camera. The monitor uses a 60m digital wireless receiver which matched the 60m transmitter for the camera. The bullet camera is ideal for caravans and motorhomes where you can fix in the skirt of the vehicle. This is usually a single skin of ABS or fibreglass and should not affect any water ingress guarantees. The monitor is normally hard wired in and comes with a 3m lead that extends to the power and connector for the receiver. There is the option to add an extension lead if needed. This is to allow you to locate the receiver in a more suitable location. The camera has a short lead to the transmitter, but there is the option to add an extension lead if required. This might be useful if you have a trailer with a lot of thick steel as moving the transmitter will improve reception.
