Saw an article about some Police being caught on film by a home camera while "planting" a pistol during a search.
I think, all told I have got about $2600 in the system. A camera in every room and 360 around the house. Punch in 3 numbers to get it going, four numbers includes the alarms.
Imagine searching a house where you can rip the alarm system out of the wall and the damn horns will not stop.
