Seismic and Acoustic Sensing
Designed to reduce operator burden the Mini Mk3 is ideally suited for operations where weight and size are critical factors. Using data fusion and sophisticated algorithms, this Unattended Ground Sensor (UGS) can detect and classify movements of humans and vehicles whilst filtering out unwanted alarms. Using encrypted communication (AES-256), alarm data is transmitted to the base station by the built-in radio.
Mini Mk3
If “radio silence” mode is activated or the communication is interrupted, alarm data is stored within the device until requested by an operator or the communications link is re-established. Each Mini Mk3 sensor operates as an individual node in the Mesh network, and can relay data from other Unattended Ground Sensors (Mini/Scout/PIR) back to the base station if required.
