Last week I used my new CCTV camera system for the first time on a 150 mile towing trip. The system comprises a 'standard' circular reverse view 12v CCTV camera fitted into the centre of the rear panel on my Bailey Senator; this is powered by the 12S circuit (which feeds the fridge). A single RCA lead from the camera to the font of the van connected to a small wireless video transmitter (2.4 GHz), plus a second 12v lead from the 12S circuit to power the transmitter ( 8 volts).
In the car, the video receiver to receive the output from the transmitter in the van. This outputs to a 5" (colour) screen which is attached to the dashboard.
When I assembled this kit and tested it, I was impressed. A clear picture from the rear of the caravan which was activated by connecting the 12S lead and starting the engine.
In practice, things did not work out as I had hoped. The fact of the matter is that the camera reacts rapidly to changing light and these changes result in extreme variations on the monitor in the car. Adjusting the brightness to see a clear picture one minute, needed to be re-adjusted minutes or seconds later, when the angle of the sun changes. So this is a real problem. Fine if you only want to use the system when stationary; but if you want to use it on the move (as I do), then I fear I may need another type of camera?
The other issue I have is that the camera is super wide angle. This means that a vehicle travelling at reasonable distance behind, is indistinguishable; one really needs a camera that reproduces the normal rear view mirror.
Comments welcome; especially from our friend John Glassey (to who I shall email this note separately as he is an old hand at this !)
