NM-MODEYE
DO NOT CUT OR SPLICE THE CAMERA'S CABLE. MODIFYING THE UNIT IN ANY WAY WILL VOID THE WARRANTY.
Installation Procedures:
1. Unscrew the Exterior Ring and remove the Camera Eyeball from the camera assembly. Locate the Modulator switch
bank and set the channel 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. Connect a coax from the camera's Video/Power 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. Insert the Interior Base through the 2.65" hole of the mounting surface and fasten with the Mounting Ring. Adjust
the Camera Eyeball for proper viewing and tighten the Exterior Ring.
