Hydra Asset Protection System
The wireless Hydra Asset Protection System eliminates almost all nuisance alarms and greatly reduces installation cost. Combining the dual sensing technologies of an accelerometer to detect activity on the fence (or asset) and a PIR to detect human presence, Hydra requires both to activate before triggering an alarm. Hydra’s battery powered sensors communicate over a self-healing mesh network and require no infrastructure, making installation inexpensive.
