Reverse Camera need a fuse?

I am just about to install a different one to the original which will get power from the reversing light circuitry. It would be best to protect that as it will possibly rub against various spots around the vehicle and it will be a positive wire.

The principle of fuse selection is that the fuse rating must be less than the current rating of the THINNEST wire fed by it.

If the wire is rated at 2 amps, the fuse must be 2 amps or less.

Hi Mark

Our largest Infra Red camera uses 600mA so a 1A fuse would work (2A Max).

Yes it is important to fit a fuse on that camera circuit close to where you pick up the 12V source.

Mark,
I did such an install with the reversing camera at the back of the van prior to our last 2 months trip it was worth the install effort and the money.

If you are putting the camera at the back of the van, when the van/camera if not connected on my unit you get a warning on the screen of NO SIGNAL. To overcome this I put a switch in the power circuit to the screen.

Thanks everyone for your replies, I'll put one in tomorrow. Just have to see if I can find a blade fuse that small - I have heaps of old glass ones down to 300ma but the smallest blade I have seen is 3 amp.

Yes Yes Yes. Install a fuse. My original camera was not fused, camera shorted out internally which resulted in a lot of melted insulation...could have been a disaster. Would be interested to know your thoughts on rear view screen...Mine is hopeless due to reflection.

The one I have has 2 cameras (one on the back of the 'trol and other on the camper trailer).

The cables to each of the cameras come from the main wiring harness which is fused.

So, basically, I have a power wire and an earth leading to the screen. There are 2 plugs (each with about 5 contacts....a bit like the old DIN plugs used on stereos/hi-fis about 100 years ago, only about 1/3 the size).....these lead to the cameras.

So, all power comes from the fused power input.

Mine is a Polaris (originally PORON) brand......

I haven't added any extra fuses....can't really see where I could add them even if I wanted to cos everything is sealed.....
