How Dual Technology Motion Sensors Work
Detection Process
Dual technology motion sensors combine the capabilities of both passive infrared (PIR) and microwave technologies to enhance the accuracy and reliability of motion detection. This sophisticated system works by utilizing the strengths of each technology in a complementary manner, resulting in a more robust and efficient detection process.
-
PIR detecting heat signatures: The PIR component of the dual technology sensor is responsible for detecting heat signatures emitted by moving objects within its field of view. When an object enters the sensor’s range, the PIR sensor registers the changes in infrared radiation levels, triggering the detection of motion. This heat-based detection method is particularly effective in capturing human or animal movements, as they emit heat signatures that can be easily identified by the sensor.
