The crash could be overheating, maybe try heat sinks on the bt878 chips?

Usualy working at a low resolution but not a high resolution is a shared memory problem. Set shmmax and shmall to correctly for your RAM and then restart the Zoneminder service and all should work.

I had the same problem but changing to the below values improved things a lot:

Image Buffer Size (frames) 80
Warmup Frames 40
Pre Event Image Count 40
Post Event Image Count 40

There has been discusion on this before, if you search for analytics it is an interesting read.

I think you should, as Siki wrote, leave the frame rate blank and set the frame rate on the device instead.

This looks like an ownership problem, you probably need to chown -R apache.apache the video directory. I would probably first have a look at the ownership of some of those directories.

Set your linux shmmax and shmall values to something sensible for the amount of RAM in your server, then set the cameras to 640*480 or whatever then reboot and voila they will work:)

kernel.shmall should be something less than the total RAM on your server divided by 4096 say 1000000 ( 1 million) on a 4GB system.
kernel.shmax set at 180000000 ( 180 million) should be enough unless you are doing something unusual.

Yes.

If your camera only works at 30fps but you want it to modect at 15fps a workaround would be to define a monitor to get its full frame rate just monitoring then define a second monitor that gets its input from the 1st monitor but at the frame rate you want, the second monitor is setup like this: Remo...

Upgrading with reinstall to 1.24.2 fixes this 99.99% for me.

Are you setting the 15fps on the camera? You should set the frame rate on the camera and let ZM go as fast as it wants, ie set its frame rate to a nominal zero.

Have you tried?

chown -R apache:apache /srv/www/htdocs/zm/events

It should work apparently: http://www.zoneminder.com/forums/viewtopic.php?t=12126&highlight= Maybe set it to record and see whether the "Source" column turns green and you start seeing jpgs appearing in the events folder. You should be testing it on a client PC not the server, and usin...

shmall should be the total ram available to linux divided by 4096. E.G. if you want to allow it 3GB then shmall = 732422
shmmax = 180000000 works for me using an image buffer size of 80.
