Adjust the Dip Switches according to the installation location of the PIR Camera for ideal performance. If Dip
Switch settings does not match with installation environment, the PIR Camera
’s performance will be hindered and
may cause either false alarm or inability to detect movement.
The PIR Camera detects differences between the moving object and the background. If the object is idle (i.e. not
moving), the PIR Camera is unable to detect it.
The PIR Camera has a directional characteristic and is most effective at detecting intruder moving across field of
detection. It is less sensitive for detecting motion directly towards the PIR Camera.
The PIR Camera has about 1M of blind spot under the camera when mounted at 2M high. The blind spot area will
enlarge if you mount the PIR Camera higher than 2M, and reduce if lower than 2M.
Unless required, we suggest keeping the PIR Camera mounting location at 2M for optimum performance. If you
change the mounting height, please conduct detection test to make sure the PIR Camera can detect intruder
normally at the chosen height.
