Surveillance camera forums?

[tools]

Hi, can anyone direct me to technical video camera surveillance forums where I can learn about setting up a DVR-based home security system? I've been googling with less than steller results.

Are you wanting to set up your own system or just want to be a member of a forum? A setup isn't that hard.

I want to set up my own system, but would like to see camera and other equipment reviews, find out if I need a central power supply for all cameras, see if 12V or 24V cameras are better, figure out how to access the system over the internet, etc. etc.
