Digital Multi Function Detector designed for ATM application. Micro controller based. Detects intrusion attempts on ATM by vibration, cutting and drling. Operates on multiple advanced detection logic for added security. Sensor is triggered if 3 knocks are detected within 30 seconds (subject to knocks being equal to or higher than set sensitivity level). Sensor is triggered if a big knock (2X or higher than set sensitivity level) is detected Sensor is triggered if continuous vibration is detected for 5 seconds. Any one detection logic required to trigger the sensor.
