PIR Motion Sensor
Our ceiling mounted PIR motion sensor can detect the target area in a 360° cone. To meet the needs of different users, we provide two detection principles: infrared light and microwave. The infrared motion sensor uses PIR pyroelectric elements, which are low in cost and good in stability. The microwave motion sensor uses 24GHz millimeter wave radar, which is not affected by the environment, temperature, dust, and has a low false alarm rate.

Infrared PIR motion sensors installation Instructions
1. select the appropriate position, the mounting plate is fixed with screws to the ceiling, and then put the detector
2. recommended mounting height is 2.5 ~ 6m
3. near an air conditioner installation location should be avoided, rapidly changing electric fans, refrigerators, ovens and can cause the temperature of the object, while avoiding direct 4) front of the detector lens to avoid blocking object, so as not to affect detection results
Infrared PIR motion sensors instructions
1. according to the instructions good line, and then covered with the probe cover cassette
2. power indicator is flashing, the detector self-test and after 60s light is off, the detector enters the normal state of detection, if the moment someone walking within the coverage area of the detector, LED indicator lights, while the alarm output RS485
3. LED ON LED indicator control skipping prompted, does not affect the normal operation of the detector
