GXV-3672-FHD IP Camera
GXV-3272-FHD Full HD camera, nighttime capability, supports a power over ethernet connection.
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 three GXV-3672-FHD cameras on home built Core i7-3770 CPU @ 3.40GHz, 16GB, Asus P8Z77-V motherboard, at idle (monitoring the three low def feeds, no alerts) I see a load average about 0.6.
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.
