Notes
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.
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.
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.
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.
