Closed circuit fence detection systems, such as Medusa manage to deter and detect intruders efficiently. In a closed-circuit monitoring, currents of a circuit are measured constantly. The corresponding system is located within a fence structure. Unauthorised opening leads to a disconnection of the conductive sensor wires and triggers an alarm.
Detection with Medusa is nearly invisible due to its hidden and therefore tamper proof sensor wire. It can for example be installed directly in the tubes of welded mesh mats. Thus, the system is virtually free of unrequested/spurious alarms. Medusa can be integrated or mounted in almost all fence types and additionally secures gates and wall copings as well.
