Now there is a system available that will let you know "Friend or Foe" the instant a vehicle enters your drive. We call our system the Invisible Gate. The entire system works without wires or buried cables on drives up to 5 miles long! No connection to electrical power is required. Protech’s wireless drive alarm sensor system takes home security and the protection of your family to a level unachievable by ordinary security systems. Our motto "Protection that begins at the property line" says it all.
