Note: Pay attention to the following precautions
to prevent IR reflection:
1. 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.
2. Make sure that there is no reflective surface
too close to the camera lens. The IR light from the
camera may reflect back into the lens, causing
reflection.
