WebThe PIR sensors do not emit radiation but simply receive the one that the objects nearby are naturally emitting. The basic functioning is that the passive infrared sensors trigger the alarm when there is an anomaly in the infrared waves measured in the room. WebPIR Delay is an abbreviation for “Passive Infrared Response Delay”. It is the amount of time between the motion sensor on a trail camera being triggered and the camera taking a picture. This delay can vary from one camera model to another and can range from 0.1 to 0.5 seconds. The PIR Delay is an important factor to consider when choosing ...
