How it works:
The PIR sensor is a
passive
infrared motion sensor, meaning it detects
infrared radiation rather than projecting it (unlike a security camera with
infrared night vision, which is
active
infrared). All objects emit this infrared
radiation (we commonly call it “heat”) and the infrared sensor looks for
any of this radiation which moves.
The passive sensor is not infallible – in particular, it cannot detect objects/
people which are the same temperature as their background. So a human
being moving about on an extremely hot day might go unnoticed. Also,
a security camera with active infrared night vision in the same vicinity as
the infrared sensor may give false alarms (particularly if it is a moving PTZ
system).
