What Is A Pir Motion Sensor; What Is New In Version 3 - Camtraptions PIR V3 Manual

What is a PIR Motion Sensor?
All objects emit energy in the form of invisible infrared radiation. A passive
infrared (PIR) sensor detects movement of infrared-emitting sources within its
field of view. This allows it to sense when an animal passes in front. The term
"passive" refers to the fact that the sensor does not emit radiation but instead
monitors the levels if infrared radiation falling on it. As a result, PIR sensors
are very energy-efficient.
What is new in Version 3?
The following new features have been add to this PIR:
1) Added an integrated wireless transmitter, compatible with Camtraptions
Wireless Receivers.
2) Redesigned sensitivity algorithm delivers faster response time with
more reliable false trigger filtering.
3) Now supporting three distinct operating modes: Still mode, Video mode
and Legacy mode
4) Support added for a wider range of cameras and flashes
