Unable to Get Static Frame Rate With Continuous Record

Post by tungstencoil »

Hi,

We have ZoneMinder set up for continuous record ("Function = Record") for multiple networked cameras. The cameras themselves are set to stream at 30.0 fps. ZoneMinder is set to record at 15 fps (Source-->General-->Maximum FPS = 15).

I can verify the cameras are streaming 30 fps. It is my understanding then that ZM should be recording 15 fps, but the status typically shows between 3 and 6 fps. Looking at the resultant video after transcoding it into a movie, I would have to say that the low frame rate seems accurate; it is monitoring a very busy area and things jump around quite a bit. Each segment is capped at 300 seconds, and one can also see that the actual seconds recorded vary by +/- 5%.

The server does not seem to be under exceptional load. The machine is a modern dual-core server with 4GB recording just 4 network cameras.

Any tips on troubleshooting or correctly configuring this would be appreciated.

Thanks!

You need to feed ZM the corect frame rate or it will guss 30 /2 =15 but zm is not god at estimating that with network cams because it has to take apart the stream. Generaly its something like /strem.asp?cam=1&fps=15 but it will depend on the cam
