All of this is moot if the guy is just walking in the gate behind a car or has painted over one of the IR beams at the gate. CCTV is retroactive unless you have a 24hr monitoring service on site. 100 strand elec fence is only as good as the maintainance of the energiser, the bobbins and the foilage growth along the fenceline. If your fence clicks all night because of a short the b@stards will know that your fence is not being maintained. You have to create an awareness amongst residents. They must wait for the gate to close behind them before they drive off. They must question unknown people in the complex.
