ZoneMinder Forums

Hello.

I have just installed Zoneminder 1.24.1 from Ubuntu 9.10 repository.

I have two cams to configure.

USB Philips web cam
Axis 207w IP web cam.

I have been able to configure (set up) both cams, but anyone works properly.

USB Cam
I see a static black scream nothing more happens

IP (remote) Cam
I can’t see anything, only a static white scream.

I have just read zm.conf and apache2.conf configurations files.

Both files are correct (normal).
Also I have been searching for a solution in the forum and wiki, and I haven’t found anything useful.

USB cams configuration:

Name: Philips
Source Type: Local
Function: Monitor
Maximum FPS: none
Alarm Maximum FPS: none
Device Path: /dev/video
Capture Method for linux version 2
Device Channel: 0
Device Format: PAL B
Capture Palette: RGB 24
With: 320
Height: 240


IP cams Configuration

I have done part of the configuration using preset options.
Preset option: Axis IP, 640x480, jpeg
Function: Monitor
Remote Host name: xxx.yyy.zzz.sss (Web cans IP address)

With each cam and configuration in the main scream (ZM – Console) the source column is in red.

I have copied the last few records of the zmwatch.log.

Always the same message appears:

I have tried these solutions without success:

I have tried to compile the source code with –enable-nmap=yes option but when I execute “make installâ€

I have the same problem.

I have a uvc usb webcam with an Alcor chipset.

zmu detects the camera, but the ZoneMinder web interface shows the camera in red. I am attempting to setup my camera with the v4l2 support in ZoneMinder.

I posted the output of my zmdc.log to http://pastebin.com/m3377460e

i've set the SHM_KEY in options/system settings to what the errormessage says ... and the error went away ... and the whole system seemed to work (better) ... strange but hey it worked!

in your case put the "7a6d0002" in SHM_KEY

of course the shmall and shmmax settings have to be just right, some linux OS's apparently multiply shmall by 4096 (check your ipcs -l output for changes)
