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 | |
