PIR

The PIR is a compact, rapidly deployable passive infrared sensor for fast and reliable detection of moving targets and their direction of travel.

Thermal Sensing

The PIR acts as a thermal barrier, detecting infrared radiation emitted by an object moving across the sensor’s field of view. The PIR uses advanced algorithms to filter false alarms, and to determine the direction of travel of a moving target. Encrypted communication (AES-256) ensures alarm data is securely transmitted to the base station by the built-in radio. If “radio silence” mode is activated or the communication is interrupted alarm data is stored within the device until requested by the operator or the communications link is restored.

Passive Infrared Sensor

The PIR consists of a Module Core unit with integrated radio, GPS receiver, battery, and an interchangeable PIR Module. There are three PIR Module variants: short, medium and long range, with different detection ranges and fields of view. The PIR module can be connected as an external component to any type of other Flexnet sensor.

Whether deployed as a standalone device or as a part of a more sophisticated multi-sensor system, the PIR provides powerful detection capabilities ideally suited for the surveillance and protection of troops and critical assets. Each sensor operates as an individual node in the Mesh network, relaying data from the other sensors to the base station.
