Rear Vision Camera Interference

[Peter Norman]

This question is not about wiring, but about wireless. I purchased a 2.4ghz wireless rear-vision camera system ... camera mounted on back of caravan powered from the caravan tail-lights circuit; display unit mounted on VE Berlina dash powered via cig lighter socket. The image is full of interference. If I remove the monitor from the car, the picture quality improves. Could the in-car interference be caused by the in-car Blue Tooth kit? Anybody had this problem and solved it? Cheers, Peter

Bluetooth runs on the license free 2.405 ghz range so could certainly cause interference. Also, I think you're pushing the range of the device to it's limits, if you consider it has to travel through 2 walls of the caravan and the car itself. This makes it much more susceptible to noise and interference in the signal. Is it specifically designed for caravans/longer range?

Yogi_b ... thanks. The range is advertised as up to 80 metres. I have moved the transmitter aerial a couple of times. Initially it was mounted on the inside back wall of the 'van. I moved it to the outside ... it fitted snugly inside the RHS direction indicator assembly (i.e weather-proof). I have not yet tried to position for direct line-of-sight. What I will do next is temporarily mount it on external RHS of 'van as see what happens. This will be at the week-end at the earliest ... I will let you know. Cheers, Peter

the wireless reverse camera setups are pretty hopeless. i'm yet to see one that is not full of interference, even hooked up on a Honda Jazz (about 2 metres between receiver and camera)

yep ive installed a couple of those wireless type cameras at work and both times there was heaps of interference so i just used the cable in the kit that connects the camera to the screen. your better off buying a decent kit which comes with plugs so you can wire it to your caravan.

The advertised range is often the theoretical range that the antenna and not very often a good indicator of the actual range. With the amount of noise created by an engine and all the wiring that runs around a car it would be veeeery difficult to shield the signal from all that interference. I agree with the others in the idea to extend the cable and cable tie it alongside the trailer wiring :-/

Ha! 80m in waveguide perhaps.

That band is also so full of crap, you are pushing it uphill.....

Me too tried a wireless one, too much interferance, got a cable one good as gold

Dazz

Thanks to all who responded. This is what I did. As usual I hooked up the caravan to the VE and got the same interfence as before. I then moved the combo until I had clear line of sight from transmitter aerial to monitor screen, and got the same interfence as before. I then parked my wife's car (Astra) in front of the VE and moved the camera display unit to the Astra, getting no interference and good pictures when I did not have line of sight. (the Astra doesn't have Bluetooth). What I am going to do next is remove the whole wireless system from the VE/caravan and install it on the Astra ... my wife has trouble backing the Astra anyway, so she'll be happy. I will then install a wired system in the VE, with two cameras, one on back of car and the other on back of caravan. Why go to all this trouble? I am in my 60s and can't turn my neck around as well as I could in my FX when I was 18. So the cameras make things a bit easier. Thanks guys for all the good advice. Cheers, Peter Norman
