1, Infrared induction
PIR sensor will not emit any light or radio when it is ready to detect. It will not be detected in advance. People or animals passing by have body temperature. PIR detector can detect the infrared radiation from their body temperature, and then push the alarm information to App.
2, Wide Angle
The PIR sensor provides 128° side wire, 128° down view, and provides an effective detection distance of 10 meters. The mounting bracket can adjust the detection angle of the sensor, and can adapt to more use scenarios.
