ps i turned on debuging, nothing apears to be wrong... except :
this is when i run it in 640x480:
[Unable to extract subheader from stream, retrying]
but as i read on forums this is kinda normal...

if i run it in 320x240 i get something like this :

10/24/09 18:40:54.276036 zmc_m4[8723].DB3-zm_remote_camera_http.cpp/868 [Got boundary '--myboundary

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.

ok, i'l give it a try, one more thing where can i get list with crash signals :

eg : crashed, signal 6
or : crashed, signal 10
or : crashed, signal 255 ?

thanks

well i did what u said, but still same problem... i'm geting lots of events like this. please advise. thanks

I've seen something similar on cheap cameras. I've no experience of the ic-1500 but it looks like it's failing to send a complete image. Could be some unusual timing issue where 15fps hits a frequency that occasionally coincides with a broken image being served. It does seem to be camera at fault though, and you may be able to verify that by watching the stream direct for long enough - if the viewer is settable to 15fps.

Workarounds - well, you know already changing fps will work.

Alternatively, amend your modect zone information to require more than one or two frames difference before it acts. That way these blips shouldn't trigger an event without affecting too many genuine events like those gates being opened.

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:
Remote Host Name = localhost
Remote Host Path = /cgi-bin/zm/nph-zms?mode=jpeg&monitor=5&scale=100&maxfps=15

obviously changing the monitor=5 to whatever is the 1st monitors number.

ok, so i'm back, i still have same problem with this camera, but if i watch the stream i can see those weired events also (camera problem), so i have set up a script to delete fake events, if alarm frames is lower than 4, delete the event, but every day at the first event zm gets alarm than gets stuck...and will record all day as an event ? how can i solve this, someone said that i should set it up so it wont record only if there are 2-3 alarm frames, but i have no idea how to do that... thx
