FWIW.....I've tried a lot of different cameras and in my opinion you just can't beat "biting the bullet" and wiring up your system. Granted, I'm lucky to have a crawl space and roomy attic, but one weekend had 6 different video feeds going very neatly to my office desk and a processor and video switch. I ended up using a Costco system that includes 4 color cameras, cables and a 4 channel processor with a removable 250GB harddrive. $299.00. I can view the cameras remotely with myhouse and at night I use AHP to switch on floods for the camera points. The floods are also triggered by motion sensors which also trigger the motion detection in the processor. Doing a lot of fine tuning right now, but its lots of fun! I play with the wireless cameras (put one on the bottom of one of them battery powered RC helicopters) but for hardcore surveillance, I'll stick to wires.
