Hi,
My first post.
I am an IT person and we have here a geovision capture card and Windows machine. I set it up with only 2 cameras several years ago and we need to upgrade. My knowledge od CCTV is somewhat limited.
My linux knowledge is moderate to advanced.
It seems as if i need to add some form of Network camera(s) as i've been reading.
(PS : I know the geovision card is unlikely to work and I will probably have to replace it.)
so my questions..
1. Forgetting capture cards for the moment, It seems as if Network cameras produce an mjpeg stream and this software can capture this and store it. Where is motion detection done to decide if to store it or not? Camera of PC?
2. It seems as if Network cameras are generally configured with a web browser, some requiring Active X controls. Can I use these type of cameras by configuring with a Windows PC and then capturing the stream with this linux software ?
3. Camera Lux settings. All our current cameras are infra red with what seems like infra red LED's round the side. Are these classed as zero lux cameras ? I've seems 0.5 lux camera, are these considered night vision camera? I'm a bit lost here. Are there good enough night vision Network cameras?
4. What can a Windows PC do with this software as a 'viewer' only. It seems you can point a web browser to this PC ? can you view / review etc.
5. Can you reduce the FPS you capture off Network cameras, the more you add, to keep server performance up ?
6. I hope thats it for now
Thanks in anticipation of any help
Jeff
