My thinking was that movie compression works by storing deltas between images rather than keeping each frame in full so should be "smaller".
I have done some experiments (see below) using cvlc to capture the RTSP stream from the camera.
An hour's worth of data in .ts (MPEG) video format comes in at 312MB. An hour's worth of photos (captured at a rate of 1 every 4 sec by zoneminder) comes in at 640MB.
That's not necessarily a fair comparison as I don't know what frame rate the video is at (how do I find out?) but it's a good saving so far.
VLC will play a .TS file. It will also give you information about the file - Ctrl I will display that.
