On busy systems, ZoneMinder performs better if the frame rate is limited at the camera instead of the ZM source like this:
On busy systems, ZoneMinder performs better if the frame rate is externally limited at the camera.  For example, to limit capture to 10 fps, set:


   Remote Host Path: nphMotionJpeg?Resolution=640x480&Quality=Standard&Framerate=10
   Remote Host Path: nphMotionJpeg?Resolution=640x480&Quality=Standard&Framerate=10


On the ''Source -> General'' configuration page in ZoneMinder, leave the '''Maximum FPS''' field empty.

The "Panasonic IP" monitor preset in ZoneMinder is compatible with these Panasonic netcam models:

  • BL-C1
  • BL-C20
  • BL-C30
  • BL-C101
  • BL-C111
  • BL-C121
  • BL-C131
  • BL-C140
  • BL-C160
  • BB-HCM381
  • BB-HCM511
  • BB-HCM527
  • BB-HCM531
  • BB-HCM547
  • BB-HCM580
  • BB-HCM581
  • KX-HCM10

All members of the BL and BB model families are likely to be compatible, including PTZ support. The model name suffix indicates the market. For example, the BL-C140A is for North America, the BL-C140E is for Europe, and the BL-C140CN is for China.


MJPEG Configuration

Example

 Monitor Page -> Source Tab ->
 Remote Protocol: HTTP
 Remote Method: Simple
 Remote Host Name: 192.168.1.254
 Remote Host Port: 80
 Remote Host Path: nphMotionJpeg?Resolution=640x480&Quality=Standard
 Remote Image Colors: 24 bit color
 Capture Width (pixels): 640
 Capture Height (pixels): 480
 Preserve Aspect Ratio: Off
 Orientation: Normal

Example for Old Firmware

Change nphMotionJpeg to nphContinuousServerPush or cgi-bin/nphContinuousServerPush if the camera has old firmware like this:

 Remote Host Path: cgi-bin/nphContinuousServerPush?Resolution=640x480&Quality=Standard


Parameters

In MJPEG mode, ZoneMinder can sustain approximately 5 fps from a Panasonic netcam. In ideal conditions the maximum is 30 fps.

The Resolution parameter can be one of 640x480, 320x240, or 160x120. The Quality parameter sets JPEG quality and can be one of Clarity, Standard, or Motion.

MJPEG Frame Size Quality=Clarity Quality=Standard Quality=Motion
Resolution=1280x1024 ? ? ?
Resolution=640x480 50kB 30kB 20kb
Resolution=320x240 25kB 15kB 8kB
Resolution=160x120 8kB 5kB 3kB

The optional Framerate parameter can be 0.1 through 30.00 frames per second in one-tenth increments. For example, to take an image every other second:

 Remote Host Path: nphMotionJpeg?Resolution=640x480&Quality=Standard&Framerate=0.5

Performance

On busy systems, ZoneMinder performs better if the frame rate is externally limited at the camera. For example, to limit capture to 10 fps, set:

 Remote Host Path: nphMotionJpeg?Resolution=640x480&Quality=Standard&Framerate=10

On the Source -> General configuration page in ZoneMinder, leave the Maximum FPS field empty.

RTSP/MPEG4 Configuration

Note: Low end models like the Petcam only support MJPEG because they do not have an MPEG4 encoder.

Example

 Monitor Page -> Source Tab ->
 Remote Protocol: RTSP
 Remote Method: RTP/Unicast
 Remote Host Name: 192.168.1.254
 Remote Host Port: 554
 Remote Host Path: nphMpeg4/g726-640x480
 Remote Image Colors: 24 bitcolor
 Capture Width (pixels): 640
 Capture Height (pixels): 480
 Preserve Aspect Ratio: Off
 Orientation: Normal

Parameters

Audio can be disabled on models that have it by changing g726 to nil like this:

 Remote Host Path: nphMpeg4/nil-640x480

Available resolutions are:

 Remote Host Path: nphMpeg4/g726-160x120
 Remote Host Path: nphMpeg4/g726-320x240
 Remote Host Path: nphMpeg4/g726-640x480
 Remote Host Path: nphMpeg4/g726-1280x1024

Note: Only high definition models support the 1280x1024 resolution.

Performance

In RTSP mode, ZoneMinder can get 30 fps from a Panasonic netcam that has an MPEG4 encoder. The raw idle RTP output of a quiet scene for these cameras is approximately 400 kbps, or 5GB per day.

To force a particular MPEG4 quality, set the minimum and maximum bitrates to the same value on the "Setup -> Video Streaming" tab of the web interface built-into the camera.

ZoneMinder transcodes the MPEG4 stream to add a banner or stream through the web interface. Doing this on one 640x480@30fps stream can consume an entire core on a modern CPU. If the CPU becomes overloaded, then the zmc process will crash and the Feed Watch page will be blank or show the broken image icon. An easy way to reduce CPU load is to set the "Maximum FPS" field on the monitor General tab to 15 or less.

Model Notes

BL-C140A

ZoneMinder must authenticate with a username and password to use the BL-C140A. Using the anonymous guest account will result in a black box or this error in the zmdc.log file:

 zmdc.ERR ['zmc -m 1' exited abnormally, exit status 255]

Put the credentials under the Source tab in the Remote Host Name field like this:

 Remote Protocol: HTTP
 Remote Method: Simple
 Remote Host Name: MyUser:MyPass@192.168.1.254
 Remote Host Port: 80
 Remote Host Path: /nphMotionJpeg?Resolution=640x480&Quality=Standard
 Remote Image Colors: 24 bit color
 Capture Width (pixels): 640
 Capture Height (pixels): 480
 Preserve Aspect Ratio: Off
 Orientation: Normal
