Traditional security systems don't work here but that doesn't mean they should be left unprotected.
Thieves break into substations to steal wire and in the process put themselves and the continued operation of the site at significant risk. If they get to the point of stripping ground wires then a small theft becomes an expensive and time consuming repair. Bait the copper spools with MOBILELOCK and put Bluetooth wireless motion sensors (DS610) inside the closed areas and Bluetooth wireless door sensors (DS620) on the insides of the access doors. Even connect a Bluetooth wireless cable lock or two (DS630) around the gate entrance which will alert if it is opened or cut. MOBILELOCK provides round-the-clock portable security.
