NV-214-A-M Product Installation Manual
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with a dry cloth.
7) Install in accordance with the manufacturer’s
instructions.
8) Only use attachments/accessories specified by the
manufacturer.
9) Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has
been damaged in any way, such as a power
supply cord or plug is damaged, liquid has been
spilled, or objects have fallen into the apparatus,
the apparatus has been exposed to rain or
moisture, does not operate normally, or has been
dropped.
This installation should be made by a qualified
service person and should conform to all local
codes.
WARNING  Do not install the unit in an environ
ment where the operating ambient temperature ex
ceeds 122°F (50° C). No naked flame sources, such
as lighted candles should be placed on the
apparatus.
WARNING  Do not interconnect multiple
outputs.
WARNING  The apparatus shall not be exposed
to dripping or splashing and no objects filled with
liquids, such as vases, shall be placed on the
apparatus.
WARNING  For safety, never put NVT signals
in the same conduit as highvoltage wiring.
WARNING  Do not restrict airflow around any
active powered NVT products.
TO REDUCE THE RISK OF ELECTRICAL SHOCK,
DO NOT REMOVE COVER OR BACK. NO USER
SERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
WARNING: TO REDUCE THE RISK OF ELECTRI
CAL SHOCK, DO NOT EXPOSE THIS APPARATUS
TO RAIN OR MOISTURE.
IMPORTANT SAFETY INSTRUCTIONS
Wiring Tech Notes
1. Use point-to-point Unshielded Twisted Pair wire, 24-16 AWG
(0,5-1,5mm), stranded or solid, Category rated wire.
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 elec-
tromagnetic fields (in accordance with National Electrical
Code, local, or other local safety requirements).
3. Measure the wire distance.
4. DO NOT USE individually shielded twisted pair. Overall
shielded, multi-pair (6pr +) or foiled Cat5 is OK.
5. DO NOT USE UN-TWISTED WIRE.
6. Due to near-end crosstalk, don’t send a transmit and a receive
signal in the same wire bundle over 1000ft (300m). Exceptions:
Category 5 or better cable, up to 2,000 ft (600m) are OK.
7. Passive NVT NV-214A-M will transmit receive “up the coax”
P/T/Z control signals up to 750ft (225m)
8. Unless prohibited by Electrical Code, the camera and NVT
should float, relative to earth ground. This will reduce sensi-
tivity to lightning strikes.
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 meas-
uring the loop-resistance out and back.
Wire Resistance per 1,000ft (300m)
24 AWG (0,53 mm) = 52 ohms
23 AWG (0,57 mm) = 42 ohms
22 AWG (0,64 mm) = 33 ohms
20 AWG (0,81 mm) = 21 ohms
19 AWG (0,91 mm) = 16 ohms
18 AWG (1,02 mm) = 13 ohms
Use the correct receiver for your wire distance. If your distance
does not exceed the maximum passive distance, use a second
NV-214A-M at the monitor end. Otherwise, visit nvt.com to
select the appropriate active receiver.
Connecting the Camera End
1. Connect the baseband video signal from the camera to
the NV-214A-M.
2. Connect the UTP output of the NV-214A-M to existing or new
unshielded twisted pair wiring by attaching each conductor of
a twisted pair of wires to each screwless terminal. Note wire
colors so that polarity may be observed at the receiving end.
Connecting the Monitor End
1. Connect the UTP conductors to the screwless terminals of the
NV-214A-M. Observe polarity.
2. Connect the NV-214A-M to the DVR, video monitor, or other
video equipment.
3. Confirm that your monitor or other receiving equipment is
correctly terminated with a single 75W terminator.
Troubleshooting
If you are experiencing problems, attempt to simplify your setup.
Test each cable segment separately. For example, test the cam-
era and monitor together without the other equipment. Then add
in the NVT transceivers, back-to-back. Test each segment of a
long cable-run independently. Attempt to isolate the problem.
Customer Support
NVT customer support is available for consultation from 8:00 AM
to 5:30 PM PST Monday through Friday. In addition, emergency
after-hours callback support is available.
