When installing the camera, please install the camera
angularly (the angle between the sensor and the detect-
ed object is larger than 10°) for effective motion detec-
tion. If the moving object approaches the PIR sensor
vertically, the sensor may not detect the motion events.
For reference:
• The PIR sensor’s detecting distance: 6m (by default)
• The PIR sensor’s detecting angle: 120° (H)
• The Ideal Viewing Distance
The ideal viewing distance is 2-10 meters,
which enables you to recognise a human.
