PIR Sensitivity Settings Explained
PIR Sensitivity Settings Explained
Settings Overview
PIR sensors allow for the detection of movement, through an infrared sensor in combination where present with a microwave detector. The configuration parameters, such as the sensitivity and the intervention times are adjustable according to needs and remotely.
The choice of the motion detector configuration parameters is made according to the detection needs. We recommend carrying out a series of tests to evaluate the right compromise between sensitivity and trip times, considering that greater sensitivity affects battery consumption.
Settings Breakdown
Pyro Sensitivity
Represents the sensitivity of the sensor for infrared movement detection, with values ranging from the least sensitive to the most sensitive.
Pulse Counter
Sets the number of pulses that the infrared motion detector must consider to generate an alarm condition, considering the blind time and the window time.
Blind Time
Blind time is the pause time that passes between one detection and another of the infrared motion sensor. This time allows to make the survey very strong avoiding false alarms.
Window Time
It is the overall evaluation time starting from the first detection of the infrared motion sensor, within which the subsequent pulses must be detected.

The sum of the blind time for the number of pulses must not exceed the window time otherwise the detection is not performed.
Enable Microwave
With the setting turned on, the detector will require a confirmation from the Microwave sensor after the PIR has detected movement before an intrusion. With the setting turned off, the detector will utilise only the PIR sensor and will trigger an intrusion soley from this.
