I've just moved house and am having a bash at my second ZoneMinder (v1.28.0) install. So I'm still learning a lot, and am very open to criticism / suggestions.
The Zoneminder part of it is great, Ubuntu Server, running on a super duper ex corporate Dell 1U server computer with dual quad core processors (x8), 6GB ram, SSD, etc...
But I am having an issue with a camera I've just installed... As the title would suggest it's a 3 Mega Pixel Hikvision DS-2CD2032-I.
Every so often, I get 4 seconds of images with glitches, this triggers Zoneminder off to record, so each day I'm amassing hundreds of garbage recordings.
It may be that the camera settings could be improved on.. I'll publish these further down. The camera is connected to the server via a Netgear 10/100Mb/s hub. It's powered by passive PoE (Injector / Extractor) and the Ethernet cable is only about 5m long.
However, I have a long Cat6e cable from this hub to my wireless router, so I can also view the camera feed directly from any computer, and yes, it happens on all viewers: with VLC player using rtsp link; XBMC / Openelec (raspberry pi reading a .strm file containing the rtsp link); VLC on my android phone etc.. So I think the issue is more the camera or network.
A good image from Zoneminder:
Here are some of the glitches recorded by Zoneminder:

Code: Select all
Can / should I lower the FPS from 25? Does it need to be that high for CCTV? Can / should I lower the resolution?
Is it too much data for my 100MB/s network?
Or have I got a camera issue? is it in need of a firmware update?
Any hints would be welcomed.
Thank you, Scott.
