An IR sensor is located near the TV and wired to the receiver, which can be many feet away in the equipment rack. The receiver has an amplifier and an "IR blaster" that showers IR signals to all ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal.

The video demonstrates how to wire up a Passive Infrared Sensor (PIR) using 4-core security cables. All Gallagher inputs are balanced 4-state inputs and must have two 4k7 resistors wired at the device ...
