Notes:
For the camera supports IR, you are required to pay attention to the following
precautions to prevent IR reflection:
 Dust or grease on the dome cover will cause IR reflection. Please do not remove
the dome cover film until the installation is finished. If there is dust or grease on
the dome cover, clean the dome cover with clean soft cloth and isopropyl alcohol.
 Make certain the installation location does not have reflective surfaces of objects
too close to the camera. The IR light from the camera may reflect back into the
lens causing reflection.
 The foam ring around the lens must be seated flush against the inner surface of
the bubble to isolate the lens from the IR LEDS. Fasten the dome cover to camera
body so that the foam ring and the dome cover are attached seamlessly.
