Record at full fps BUT motion detect on only 10 FPS?

[rash.m2k]

As above is it possible to achieve this through Zoneminder. Also I tried the record function - why does it just dump jpgs into a directory? Can it not simply dump a video stream?

I'm sure I can achieve this if I was streaming a video file - in which case I'd record at full fps using something like ffmpeg and then pass a framerate limited stream to Zoneminder, but I'm wondering if there is a proper way to do this.

The best way I've found to do this is to work the network harder by taking two feeds from the same camera. In my case, I wanted to do motion detection from a standard-def feed, but record in high def if motion was detected. Process should be similar for you.

Set up camera feed 1, the standard def feed, as usual, and make it a MoDect camera. Set up camera feed 2, the high def feed, as NODect, and have it trigger off of camera feed 1. Finally, set up a filter to delete the events from camera feed 1 after a day or so. (So if you get a spurious alarm, you can still go in and see why it triggered off on the SD feed, but not waste too much disk space keeping the high and standard def versions of both events.)

Nope. Zoneminder uses jpegs extensively internally. Think it's a relic of when all cameras used mjpeg.
