How is capture and analyse rate set?

[cmisip]

I have some monitors capturing and analysing at 25 frames/sec while others at 14 frames/sec. Same camera types with fps set at 25/sec in the camera. Is the framerate derived from system load, that is, if things take longer to complete, then zoneminder reduces the capture and analyse rate?

Thanks,
Chris

If they are local cameras these values can be set in Zonemimder. IP cameras have frame rate set at the cameras. I have foumd that some cameras can vary the rare with no ill effect on performance.
