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.
