Installation Procedures:
1. Set the channel with the switches as shown in Figure 1. Choose an unused channel that matches the tuning mode of the
televisions. With antenna tuning, choose a UHF channel from 14-69. With cable tuning, choose a CABLE channel from 70-94
or 100-125. There must be at least one blank channel on either side of the modulated channel to separate it from any other
broadcast, cable, or modulated source. When combining with cable service, be aware that digital data typically interferes
with channels 80-117, even when not subscribed to digital services. Channels 120-125 often work without any filtering.
2. Ensure that the camera is grounded with the ground strap as shown in the FCC Information. Connect a coax cable from
the camera’s F connector to the “MOD” side of the Power Injector. Connect the “TV” side of the Power Injector to the
grounded coax from a television or distribution system. Connect the 12V DC 300mA power supply to an AC outlet and
the Power Injector. The camera picture is now available on the programmed TV channel.
3. Install Camera Assembly into junction box (not included) and adjust for proper viewing.
4. Snap the dark or clear Lens Cover into the Cover Plate (not included) by pressing all four corners in simultaneously.
5. Attach the Cover Plate to the Junction Box. Silicon or similar sealant may be used as needed.
