Details please. How difficult is it to set up some kind of remote web cam. And how expensive?
I use the KISS method.
Every system I have has an inexpensive webcam attached, directed out a window, looking at critical areas. Security software watches for frame changes and records video when they do. I have the software set to beep while recording, so I know when someone pulls in the driveway or approaches a door. I have my systems networked and use Remote Desktop to view the various screens and hear the beeping.
This system combined with the motion lights covers the bases.
You can go much more expensive and elaborate. I plan to upgrade down the road with wireless IR cams and a dedicated (hidden) single system.
