I also suffer from extremely high CPU usage (> 2.0 with 2 cameras@320x240 - and it increases by more than 1 for each camera I add) This is on a fresh Ubuntu Server 10.10 install I have used motion for years, and the same setup could handle 8 cameras under Motion with no real noticable CPU load. I ...

if its an MJPEG camera, you should be able to use the stream directly

Is the location of the stream known?

Yes, you can modify that example pretty easily. There are a few ways to do this in perl, but the simplest example is system("command", "arg1", "arg 2",...,argN"); For example, if I wanted to call a shell script named "send_email.sh", with the arguments "--subject", "--body" and "--address", it may ...

Are you using MJPEG cameras by any chance?
I think I've noticed the same speedup on my MJPEG cameras, but only if I fill in a max framerate in the monitor setup

here it is:
http://svn.zoneminder.com/

Not sure how it happened, but I also noticed that my load went up from about 0.8 to over 3.0 while the framerate was all goofy. Also, recordings were very odd, with the timestamp bobbling all over the place.

Anyways, did a reboot of my server and everything went back to normal.

From what I've found, most all documentation currently available is outdated. It appears that old versions of ZM used a different control scheme (using files named zmcontrol-cameraName.pl) and worked off of a bunch of parameters passed to the script. Almost all examples I've found off of the net ...

I have 2 different cameras connected to ZM. Both of them are streaming in MJPEG. In the camera setup for each camera, I have set it to 15 FPS. In ZM, it will show anywhere from 50 to over 300 FPS. I have only been using ZM for about a week, but it always used to hang at the set 15 FPS. Somehow ...

I have a couple PTZ cameras hooked up to ZM, and have written my own control scripts. I have them both set to "Modetect".... Now the problem is, it still trips events when I use the on screen controls to pan or tilt the camera. I would expect it not to trip an event, because I told it to move. Isn't ...

ok, got some simple pan and tilt working - though I'm still trying to figure out why some of the advanced features aren't working yet (such as pan and tilt speed)

Well, I have probably over 20 hours into this now. I'm absolutely baffled that there exists no real documentation on how to do this! (I'm a very accomplished programmer, but that can't help me if there is no documentation nor anybody on the forums that can help) What I have so far: - It seems that ...

it would be nice if they used Trac or similar software so we could actually follow along with the changes that are bing made. I may pull in the source myself so that I can follow along.

just giving this a bump...

Surely someone knows how to attach a control script to a camera in ZM?

I would try a lower alarm frame count personally.. Your pre is set to 25, with an alarm frame count of to (25+10=35).
My guess is that for some reason, the alarm frame count frames aren't exported to video.

Try setting the alarm frame count to 1 or 2 and see if it improves

all I use are IP cameras, so the local/remote machine question really doesn't apply.

I'm still trying to find a way to consistently reproduce it
