Security Camera Project - Ignoring Static

, posted: 5-Dec-2009 03:02

Following on from my previous blog on this subject.  The wireless infra-red security camera I bought off TradeMe arrived yesterday and I just tested it out.

I havn't done the battery hookup or tried it outside yet, but from one end of the house to the other, through several walls, the signal was more or less perfect and the IR array was really effective for at least several meters.  Not bad for a hundred bucks.  The camera is quite sturdy too.

Anyway, to topic, instead of having the camera run all the time, I want to try hooking it to a motion detector (like on alarm/security light systems), so that it's only running when it's triggered by motion, motion detectors draw very little current I think.  So having it setup like this would probably give pretty decent battery life.

Problem is that means that at the receiver end, it's going to be spitting out "static" most of the time (the receiver just dumps composite video & a mono audio, so would be hooked up to a capture device, usb probably), which aside from being quite useless to record, also would not compress. 

So, has anybody seen a video monitoring/recording software which can "ignore static".  Linux pref, but windows if must be.

Or got any better ideas?

All that IR lighting is going to give off a big red glow....not the sort of thing I think a intruder is going to miss.

Each LED has a faint red glow in the "backs" when looking directly at the camera.  
Which is probably a good thing, remind the nogoodnicks that they are being watched.
