D-Fence’s perimeter intrusion detection systems (PIDS) are based on the latest generation of Strain Gauge Sensors made from Stainless Steel, and an electronic processing unit that converts the analog signals that come from the sensors into digital signals. The processing unit analyzes these signals and acts as a local analysis and processing system on the field, communicates with the central computer at the control center and manages the multi-purpose dry contacts. Any intrusion attempt that generates a higher weight than the pre-established one on the sensors (usually 20 Kgs.), or any attempt to dismantle or neutralize any of the system components, will immediately generate an alarm in the control center and will activate all the external systems connected like CCTV cameras, VMD, lights, sirens, GSM mobile systems. etc.
D-Fence’s PIDS operate equally good in all weather conditions, from desert temperatures of +72°C down to -25°C. The system processing unit has an auto-adjusting capability that constantly calculates the tension in the sensors and because of this, D-Fence’s systems have a False Alarm Rate of ZERO. The wide dynamic range of the sensors allows for longer intervals between maintenance operations and the robust sensors have no electric contacts, rubber parts or parts that move inside, making their maintenance very rare.
