I build CCTV security sytems in my spare time. I take used PCs usually donated, to the cause, for low cost surveillance for friends and family and word of mouth only installations.
One family friend by marriage, then divorced, caught his exwife ( On my wife's side) sneaking into his yard at 3a.m. to steal anything she could. He was missing several things over time and was thinking it was one of his neighbors stealing stuff.
Everyone that has one of my systems have caught someone sneaking, looking, watching, driving by too often, and they all love the system, and I only charge for parts I have to buy, but usually around $20.
Anyway, I look at every system as a freebee for someone esle, and he wants free internet service from his friend and neighbor.
I guess I'll have to just use this server for CCTV instead of Internet.
