Wiring Don’ts
1. DO NOT USE SHIELDED TWISTED PAIR WIRE, as this will
severely degrade the distance performance. Short runs
may be used with some signal degradation. Multi-pair wire
with an overall shield is OK.
2. DO NOT USE UNTWISTED WIRE, as this will reduce the
inherent immunity to interference.
3. DO NOT allow your installation to have bridge / taps,
loading coils, talk-battery, or MOV type protectors. Bridge
taps refer to a twisted pair connected to two twisted pairs
(such as an extension phone). Bridge taps cause
reflections as the signal propagates, resulting in ghosts in
the image.
4. If the phone company is providing the cable runs between
buildings, make sure it is dry copper (i.e. it should have
none of the following: dial tone, 48 V, loading coils, bridge
taps, switching, or long paths to the phone company's
central office and back).
5. Due to near-end cross talk, DO NOT send a transmit and
receive signal in the same wire bundle. Exceptions: Less
than 1000 ft. (304.8 m), or Category 5 cable up to 609.6 m
(2000 ft).
6. For safety, never put signals in the same conduit as high
voltage wiring.
6.2 Making Connections for Fiber Optic
Cameras
Follow the steps below to make connections for cameras with a
fiber optic transmitter added to the standard construction ("F"
suffix cameras).
1. Make all appropriate power connections.
2. Pass the supplied orange string through the mounting foot
of the camera housing and the furnished mount. Note that
a fitting is not used in the mounting foot when a
terminated fiber optic cable is used.
