Well initial testing of the in car multi-cam system began today.
It has proved three things
1.As you can see one of the camera's picture quality is pretty bad and I should look at replacing it.
2. The idea of flicking a switch in the dash and changing between cameras should work in principle.
3.I need a haircut.
I'm still waiting for the B&O VHS to arrive so cant test it with that yet, but tried it through the TV and into a capture card onto a laptop and seems to work well.
Right...now to find 1 or 2 more old high end video cameras...anyone?
