Notes

Testing camera functionality

From Fedora 20, CentOS 6.5 or Scientific Linux 6.5 using vlc:

  • vlc rtsp://<ip addres>/0 - The HiDef stream
  • vlc rtsp://<ip addres>/4 - The LowDef stream

That showed me the camera was working well, had a stable stream with good resolution on both streams.

ZM Version

I started out using zm 1.26 and had a few minor issues that I was working through. Then I got ahold of the 1.27beta and pretty much all my minor issues were fixed. Now running under 1.27 things are working smooth.

Hardware

Using two GXV-3672-FHD cameras and two GXV-3672-FHD36 cameras on a home built Core i7-3770 CPU @ 3.40GHz, 8 core, 16GB, Asus P8Z77-V motherboard, at idle (monitoring the four low def feeds, no alerts) I see a load average right around 1.5.

Camera Settings

Camera settings that appear to work well:

Primary Stream
Codec H264
Resolution 1920x1080
Bit Rate 4096
Max Frame Rate 10
Secondary Stream
Codec H264
Resolution 352x288
Bit Rate 384
Max Frame Rate 10

One oddity: the HiDef stream is detected by vlc as 1920x1088, that is what needs to be set for the monitor.

ZM Monitors

Create two monitors, one for each of the streams.

HiDef
Name Cam1
Source Type Ffmpeg
Function Nodect
Source Path rtsp://<ip address>/0?tcp
Width & Height Match the camera's Primary stream settings
LowDef
Name Cam1-low
Source Type Ffmpeg
Function Modect
Source Path rtsp://<ip address>/4?tcp
Width & Height Match the camera's Secondary stream settings

Link from Cam1 to Cam1-low. Cam1-low is where the motion detection happens. When it alarms and starts recording the HiDef feed also starts recording.

Leave "Maximum FPS" and "Alarm Maximum FPS" fields empty!. If you match the frame rate as set in the camera you'll likely get false events due to image smearing. I made that mistake and it took me a week to realize that I had inadvertently entered 10 for fps to match the camera.

Notes

Testing camera functionality

From Slackware 13.37 using vlc:

  • firefox http://<ip addres>/snapshot/view0.jpg - The HiDef stream
  • firefox http://<ip addres>/snapshot/view4.jpg - The LowDef stream

There you can see the sent frame.

ZM Version

I started out using zm 1.27.0 after some configuration issues things are working smooth now.

Hardware

Using two GXV-3611_HD cameras for now and two GXVxxxx cameras on a home built AMD Phenom 9400 CPU @ x.xxGHz, 4 core, 2GB, Asus P8Z77-V motherboard, at idle (monitoring the four low def feeds, no alerts) I see a load average right around x.x.

Camera Settings

Camera settings that appear to work well:

Primary Stream
Codec H264
Resolution 1920x1080
Bit Rate 4096
Max Frame Rate 10
Secondary Stream
Codec H264
Resolution 352x288
Bit Rate 384
Max Frame Rate 10

To enter into the camera and set the setting open a browser and go to the http://<CAM IP ADDRESS>, click on Configurations and enter the user and password, the default is: User: admin Pass: admin

After that click on the Video&Audio link in the left side menu, and click on Primary Stream, adjust the resolution and save.

    • Please note, that the selected resolution of the stream should be set exactly the same in the Monitor set up, otherwise you will not get a picture. **


ZM Monitors

Create two monitors, one for each of the streams.

HiDef
Name Monitor-1
Source Type Remote
Function Monitor
Source Path <cam ip address>
Remote Method Simple
Remote Host port 80
Remote Host path /snapshot/view0.jpg
Width & Height Match the camera's Primary stream settings
