Michael, Are you doing the video motion detection on the server or camera side?
I am a technical trainer for OnSSI.
If you are using server-side motion, pre-recording and post-recording buffers can be set up to be whatever you want them to be on the recorder. However, if you are missing that much of the beginning of any motion event you might want to reinvestigate your motion sensitivity settings.
A combination of both of these things will usually solve the issue you are reporting.
Assuming server side VMD, ONSSI also allows you to specify a frame rate during non-motion that you can set low, like 1 FPS, and then speed up on motion to 15 FPS. Then you don't get stuck wishing you could go back earlier, though at the cost of some added disk space.
You can not mingle the two - VMD and 'Speed Up' (as it's called on the recorder) are never used together.
IMHO, Speedup is typically used with VMD*. And in this case its necessary, else how does the recorder know when to 'speedup'? Right under the Enable Speedup checkbox is the On Motion one, no?
Obviously you know ONSSI far better than I and I am always excited to learn something new, so don't pull your punches!
*Assuming VMD = Video Motion Detection, i.e. the software component (analytic) which determines that motion has occurred by looking for changes in a video stream's scene that exceed user set thresholds.
Michael, has your original question been answered?
Rukmini, Marty, no more comments until / unless Michael responds.

Yes these replies have been very helpful. We are doing our VMD on the server side to answer one of the first questions asked. We will be reevaluating our setup to see if any of these changes will be helpful. Thanks again for all the responses.
