Video camera trap

[alband]

This may well fall into the [IMPOSSIBLE] category. Basically, it would be nice to leave my camera out for a several hours and have it record a video when it sees movement. That is currently possible using motion detect and using half shutter as movie start. However, it isn't very reliable (works about 25% of the time?) and also there's no way to stop the video.

The question is, would it be possible for the camera to stop the video if it doesn't see movement for a given amount of time. This would require detecting motion while recording and that might count as "Real-time video processing" which is impossible. Does the normal motion detect feature use Real-time video processing, but without any recording?

There's a couple of other aspects to it, but I'll just check whether it's possible first.

Thanks,
David.
