You have to patch into the reversing light feed with the yellow cable.

yes. That’s what I’ll do.... but wonder why it works properly without the yellow connected at all (until the engine starts)

roof light has a permanent +ve. so the camera would be powered when you are in bed.

Update.
I’ve connected both red and yellow now to the tail light. So I can have it up and running before reversing.
mice also tagged the black to the ground of the vehicle, rather than the earth in the wiring loom going to the lights.
Multimeter reads +12v on the line, just what I need.

same thing. Works with the light on, but not when the engine is running.

must be some interference.
there is a little antennae from the camera, but only about 6 inches. Is it possible to extend this and run it up the inside of rear door?

Has the van got a full steel bulkhead?

Maybe with the engine running, start with the iPad near the camera, assuming it works there, work away from it and see where you loose the signal.

Top Tip, don't have engine running, van in reverse whilst standing at the back..

Its a plastic bulkhead.
Not using the reverse line now, going on tail lights.
It works fine when the engine is NOT running.

Could the voltage to the lights be less than 12v after the engine starts, thus dropping the feed to the camera (not enough voltage)

I did have it working ONCE yesterday, with engine running, when it was still connected to reverse, but i cant repeat it.

I'd still try a high value electrolytic capacitor as close as you can to the camera. As a reservoir to help during the dip when the starter takes it's current.

just employ a man with a red flag (minimum wage) and when you get to the job, he can hump your tools out of the van, winner all ways.

The very first thing you need to check is there +12volts at the input of the camera when the engine is running?If there is then it's an interference issue.If there's no +12 volts then it could be due to the voltage going missing when the van starts.This could be caused by tapping into the interior light supply which might turn off when the van starts?

It must be down to interference, as im getting the same 12v whether the engine is running or not.

Anyone got a though on extending the antennae?
