2.2 Mounting the camera
The camera can be mounted on any surface with sucient strength to support it. The video/power drop cable from the camera can
be routed either through the cable hole in the center of the base plate, or through a cable guide in the mounting bracket.
1. Using the camera base plate as a guide, mark the location of the screws that anchor the base plate to the mounting surface. If
you are routing the drop cable through the mounting plate, also mark the position of the hole for the drop cable.
NOTE Position the base plate so that the cable guide in the mounting bracket is pointing away from any source of water,
dust, and other contaminates.
2. Drill holes for the screws that anchor the base plate to the mounting surface. Four (4) course-threaded screws are provided.
However, depending on the surface materials, more appropriate fasteners may be required.
3. Drill a 3/4” hole form the drop cable, if necessary.
4. Anchor the base plate to the mounting surface using the screws provided, or screws better suited for the surface structure.
