Our car stereo got jacked last night and I'd like to add a little surveillance. I'm wiring up a homemade video security system and need a little help. I bought a light with a motion detector and opened it up. I connected the power from a small camera to the switch inside the motion detector so that when the light comes on, the camera powers on as well. Easy enough.
Here's the tougher part. I need to record only when the camera comes on. I'm thinking of setting up a linux PVR as opposed to a VCR, but either way, I'm not quite sure how to hook that up. A simple relay wouldn't work because in both cases I would need a momentary connection to simulate a keystroke or record button being pressed. And I need a second momentary connection when the circuit opens.
As simply as possible, how would you do this?
