SURFACE INSTALLATION
1. Prepare the mounting surface:
a. Using the surface mount ring as a template, drill holes for the mounting hardware. Prepare the ceiling as follows:
• Standard ceiling: When mounting the dome camera to a standard ceiling, use either 6-32 toggle bolts (not supplied) or
#8 x 3.50-inch self-tapping screws (not supplied).
• Concrete ceiling: When mounting the dome camera to a concrete system, use 8-32 studs and nuts (not supplied).
b. Drill a hole in the ceiling for wiring.
c. Pull all wiring through the hole and terminate all wires (if not already terminated).
d. Attach the surface mount ring to the mounting surface.
2. Install the lens on the back box:
NOTE: Megapixel lenses are designed and tested to deliver optimal image quality to megapixel cameras. A standard definition lens
installed on a megapixel camera will limit the resolution of the camera and create poor image quality.
a. Remove the cover from the lens mount.
b. Screw the lens onto the lens mount. Be careful to prevent dust from entering the space between the lens and the imager. If necessary,
use clean, compressed air to remove any foreign matter (refer to the instructions shipped with the lens). Make sure the lens does not
touch the camera imager when installed.
c. Connect the auto iris lens to the 4-pin connector located on the side of the camera. Pin connections for the iris drive connector are as
follows:

3. Connect the wiring to the side of the back box:
a. Connect the network cable to the RJ-45 connector on the side of the camera. If the network has no PoE, connect a 24 VAC Class 2
power supply to the 24 VAC power connector. Refer to Wiring on page 19 for wiring connections.
b. Connect the necessary wiring for alarms and relays (refer to Wiring on page 19 for more information).
4. Install the back box in the surface mount ring by compressing the spring clips and pushing the back box through the hole. Tighten the
machine screws completely to secure the back box to the ceiling.

WARNING: Remove the foam insert from the back box before installing the system. The foam is inserted to secure the tilt ring; preventing
damage to the optical chassis during shipment.
