reverse camera for caravan

Hi Bigdog

We got a wireless set up; from Hong Kong eBay. We got it because one of the people on the Caravaners Forum was using the same model with his Jayco with very good results. We found it didn't transmit well through our Bushtracker - wishy washy picture or picture just dropped out. It work on testing inside the caravan but not the on outside - it seemed the solid caravan was just too much. We hard wired it while on the way to Tasmania.

Since our return, we got it checked out by an electronics guy, and he thinks it should work. With his help we may get it going wireless again before we head out next.

Wirless will often work OK if there is little or no solid metal sheeting between the camera (antenna) and Monitor (receiver). They are generally not recommended for 'articulated' type applications.

Yes I did and its in the bin. Would work for yonks in line of sight but stick 21ft of alloy between it and receiver and it no go.
Strangely it would work if rig wasnt moving but as soon as you moved it picture just broke up.
I bought a Polaris system that allows two cameras and wired it in. Only got 1 camera with it so bought another off Ebay and patched it in with adapters.
Not hard to do and can provide wiring diagrams to allow switching so that it works when travelling forward as well as in reverse.
One thing is I wouldnt recommend cameras with IR's Tried one and all the colours washed out in sunlight. The manufacturer (Swann) said the IR camers generally are optimised for low light and will do that in bright light.
Got one like this off Ebay

Mounted it on the top of caravan at the rear and cut a piece of plastic water pipe bend to protect it when cover on van etc.
Ran wire across roof and down the sealing strip just under the plastic insert down the wall and then thru chassis to front.
Power comes off tail lights which off course need to be on to power it. Works a treat and u cant see wiring at all. Provides an excellent view to the rear when travelling. The car one is in a Cruiser and is mounted above number plate and wiring run thru top tailgate loom and can see from towball to about 100meters behind car. PM me if u want pics etc
