You got it...5 fps at 352x288 now looks more reasonable: top - 22:10:18 up 9 days, 6:25, 12 users, load average: 0.04, 0.32, 0.58 Tasks: 107 total, 1 running, 106 sleeping, 0 stopped, 0 zombie Cpu(s): 5.7% us, 0.3% sy, 0.0% ni, 94.0% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 4066340k total, 2485444k used ...

I've done some more investigation. The Axis 2400 has two output resolutions: 352x288 and 704x576. All of the figures I gave earlier were for 352x288 - and I have just repeated the exercise again. If I set the camera to 704x576, then the framerate throttling works as expected: So: 704x576 unthrottled ...

Phil OK - so I went and got the dual Opteron, (2 x 248, 4 Gb RAM) and I have installed 1.19.5. The shared memory segment is set to 1GB, and I am currently running one Axis 2400. The behaviour noted is even more marked on this machine. With no max framerate set, zmc sits at about 20% of one CPU (16 ...

Hi there I have a set up with 3 Axis 2400 cameras, which is working pretty much fine. I have noticed some slightly odd behaviour in terms of CPU ultilisation when changing frame rates: - When I set the frame rate maximum to something reasonable (like 5 FPS), I have a single zmc process taking about ...

Phil Thanks very much for your help - your explanation got me thinking - and I had reduced the frame buffer size to 1 during some earlier shmget fun and games. Unsurprisingly it was being overwritten as soon as it arrived. Increasing this to 20 gives me motion detection, the lot - and no errors ...

OK - got some updates. 1) Restarting the machine seems to have got rid of the Corrupt JPEG data messages. The 2420 is a 24 bit camera - so it is not surprising the ZM is happier with 24 bit selected! 2) If I configure the monitor as "monitor", then I get no errors in the syslog, the stills view ...

Great - someone else with a 2420....I am having a pile of fun trying to get mine to work. I fixed all of the shmgets by: 1) Rebooting to clear everything out (clever people could probably do this without rebooting) 2) Setting my shmmax to 300 Mbytes. You could also reduce the frame buffer to 5 ...

Phil Sorry - but I'm back! It wasn't actually the timestamp alone - my camera outputs B/W - but ZM does not appear to like the images when set to 8 bit B/W. If I set to 24 bit colour, I get some action (i.e. a picture - at last) - but a truck load of errors in the syslog and zmdc.log. Here is syslog ...

Thanks Phil - got the problem. The image was the right size - but both of the cameras add timestamps to the image, which makes it bigger. Once I disabled the timestamp on the 2420....the error goes away. I now have a bunch of "shmget permission denied" - but there is enough of that on the forums ...

Hi I've got a lot further in the config, sorted out the permissions on the log files, and installed the correct perl modules. Zoneminder starts and stops gracefully from the browser - but I still have no images. I have 2 monitors defined - one Axis 2420 (Monitor 1) that is next to me...and an Axis ...

Phil

I rebuilt the whole thing from scratch - and the pcre problem is fixed. There are other problems with camera, but I will poke arond with settings before bothering you again....

Thanks for your help...

OK - I think I know what might have happened. I installed pcre-devel when I saw the first error - so it is likely that that pcre.h was not around for the original compile - so no headers, no library. I will re-compile the whole thing tonight and have another go. There weren't any obvious errors in ...

Phil Here are the relevant bits of config.h: /* Define to 1 if you have the `mysqlclient' library (-lmysqlclient). */ #define HAVE_LIBMYSQLCLIENT 1 /* Define to 1 if you have the `pcre' library (-lpcre). */ #define HAVE_LIBPCRE 1 /* Define to 1 if you have the `z' library (-lz). */ #define HAVE_LIBZ ...
