The PIR sensor detects movement up to 7 metres from the front of the sensor, it is most sensitive to movement directly in front of the sensor. An adavanced filtering programme looks for patterns of movement over a short space of time in order to decrease false alarms.
When the sensor is triggered there may be a 2 second delay before it send a stream of beeps to the receiver for 3 seconds, these beeps are different to the sound transmitted from bite alarms for easy recognition, after being triggerd there is a delay of 5 seconds for the sensor to re-arm.
