As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

Omnivision claims the first mono/IR image sensor that fits into a 3-mm module Y dimension for smaller devices.

(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 ...

Motion detectors are devices that contain either a physical mechanism or an electronic sensor that detects motion within a specific field of view. Common motion detectors include passive infrared (PIR ...

The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) provides increased capability by incorporating image intensification and long-wave infrared sensors into a single, helmet-mounted passive device.
