Large capture images skip

[captain_morgan]

I've got 4 axis cameras capturing at 1024x768, set to issue 5fps. The cameras are issuing the images, fine, but zm can't seem to capture them all and, apparently, drops several frames at 3fps. I'm not sure if it's doing it randomly because people randomly move in and out of the video area, but it will capture several frames, then the subject will jump across the screen, capturing several more frames. I have a feeling it's because of the buffers, but is there a way to correct this problem? It looks like it may be writing what I have in the image buffer, then droping sevral frames that it should be storing, then continuing to capture. I have my image buffer set to 80. I'm running an AMD x2 6000 with sata hdds and 4 gigs of ddr2 ram.

Do you get any warning messages about buffer overruns when you type the following command?

Code: Select all

cat /var/log/syslog | grep overrun

If you do then you have 3 options:
1) Reduce your image size or frame rate
2) Simplify your motion detection for that monitor
3) Increase your monitor's "Image Buffer Size". You might have to increase your shared memory size to do this.
