Wiring Notes

Wire — What to DO

1. DO use point-to-point Unshielded Twisted Pair wire, gauge 24 or

thicker, stranded or solid, Category 2, 3, 4, or 5.

2. The video signal may co-exist in the same wire bundle as other

video, telephone, data, control signals, or low-voltage power. It

is also OK to run NVT video signals in or near electromagnetic

fields (in accordance with National Electrical Code, local, or other

local safety requirements).

3. DO measure the wire distance. Use only transceivers that are

designed for that distance.

4. DO make sure the pair of wires carrying the video signal is sent

as a twisted pair (e.g. the blue-white/white-blue wires twisted

together as a pair), not a “split-pair” (e.g. blue-white conductor,

part of one pair/orange-white conductor, part of another pair).

Wire — What NOT to DO

1. DO NOT USE SHIELDED TWISTED PAIR WIRE. It will

severely degrade the distance performance. Short runs may be

used with some signal degradation (for example elevator traveler

cables). Multi-pair wire with an overall shield is OK.

2. DO NOT USE UN-TWISTED WIRE. It will reduce the NVT

product’s inherent interference immunity.

3. DO NOT allow your installation to have “bridge-taps”, loading

coils, talk-battery, or MOV type protectors. Bridge-taps are where

a twisted pair is connected to two twisted pairs (such as an

extension phone at home). Bridge-taps cause reflections as the

signal propagates, resulting in “ghosts” in the video image, and

are to be avoided.

4. If the phone company is providing the cable runs between

buildings, make sure it’s “dry copper” i.e. it should have none

of the following: dial-tone, 48 volts, loading coils, bridge-taps,

switching, or long paths to the phone company’s central office

and back.

5. Due to near-end crosstalk, DO NOT send a transmit and a

receive signal in the same wire bundle. Exceptions: Less than

1,000 ft (300m), or Category 5 cable, up to 2,000 ft (600m) are

OK.

6. DO NOT send “Up-the-Coax” Pan/Tilt/Zoom signals through

active (amplified) NVT transceivers.

Measure your wire distance

Note: All NVT quoted distance specifications include any coax in the

run. It is recommended that the wire distance be measured to ensure

that the capability of the NVT product is correct.

Wire resistance may be measured with an ohm-meter by shorting

the two conductors together at the far end, and measuring the loop-

resistance out and back. Compare your readings with the charts on

the next page.

7. For safety, never put NVT signals in the same conduit as

high-voltage wiring.

8. WARNING — to reduce a risk of fire or electrical shock, do

not expose this product to rain or moisture.
