The NVT Power Supply Cable Integrator Hub combines
a 1 Amp /channel
†
power supply with pass through
video and telemetry data, for 4 to 16 cameras, all over
UTP wire. Designed for installation in the wiring/IDF
telecom closet, or at the Control/MDF room, the Hub
consolidates connectivity via standard 4-pair RJ45
EIA/TIA 568B compliant premises wiring and pinouts.
At the camera, Power, Video and Data connections are
made using the NV-216A-PV (power-video only) or the
NV-218A-PVD transceiver via an RJ45 connector and a
single 4-pair cable. Control/MDF room connections are
achieved with a single 4-pair RJ45 cable for each
group of four cameras. Consolidated telemetry data, if
required, passes through the Hub’s Data path, and is
connected to the controller via another 4-pair RJ45 cable.
The NV-4PS10-PVD supports up to four cameras in a
compact wall- or desk-mount chassis. The NV-16PS10-
PVD supports up to 16 cameras in a 1U wall- desk- or
rack-mount chassis.
Wire Type
The Power Supply Cable Integrator Hub operates well
with Category 2 or better Unshielded Twisted-Pair
(UTP) wire, 24 AWG (0,5mm) or thicker.
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 signals near
electromagnetic fields (in accordance with National
Electrical Code, and other local safety requirements).
Do NOT use shielded twisted-pair wire unless it is
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) Do not block any ventilation openings.
8) Install in accordance with the manufacturer’s instructions.
9) Do not install near any heat sources such as radiators,
heat registers, stoves or other apparatus (including DVRs)
that produce heat.
10) Do not defeat the safety purpose of the polarised or
grounding-type plug. A polarised plug has two blades with
one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wider blade or the
third prong are provided for your safety. If the provided plug
does not fit into your outlet, consult an electrician for replace-
ment of the obsolete outlet.
11) Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
12) Only use attachments/accessories specified by the
manufacturer.
13) Use only with cart, stand, tripod, bracket, or table speci-
fied by the manufacturer, or sold with the apparatus. When a
cart is used, use caution when moving the cart/apparatus
combination to avoid injury from tipover.
14) Unplug this apparatus during lightning storms or when
unused for long periods of time.
15) Refer all servicing to qualified service personnel. Servic-
ing 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 appa-
ratus, 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 serv-
ice person and should conform to all local codes.
WARNING - Do not install the unit in an environment
where the operating ambient temperature exceeds 50° C
(20° F). The ventilation should not be impeded by covering
the ventilation openings with items, such as newspapers,
table-cloths, curtains, etc. No naked flame sources, such
as lighted candles should be placed on the apparatus.
WARNING - Do not interconnect multiple outputs.
WARNING - The aparatus shall not be exposed to
dripping or splashing and no objects filled with liquids,
such as vases, shall be placed on the apparatus.
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 ELECTRICAL
SHOCK, DO NOT EXPOSE THIS APPARATUS TO
RAIN OR MOISTURE.
IMPORTANT SAFETY INSTRUCTIONS
Power Supply Cable Integrator Hub Installation Manual
Models NV-4PS10-PVD and NV-16PS10-PVD
WARNING - Use only a Certified power cord and plug
(coupler / mains) assemblies for location installed.
WARNING - Power cord is regarded as main disconnect.
WARNING - The appliance coupler (power
cord/mains) shall remain readily operable.
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
.
Category rated. Multi-pair wire with an overall shield
(6 or more pairs) is OK.
Do NOT use un-twisted wire.
Due to near-end crosstalk, do not send a transmit and a
receive signal in the same wire bundle. Exception: Up to
1,000ft (300m); or 2,000ft (600m) Category 5 or better.
Wire in underground conduit or wet locations must be
polyethelyne-jacketed, gel-filled.Wire in plenum environ-
ments must be plenum-rated, per local codes.
RS-422, RS-485, and Up-the-Coax Pan/Tilt/Zoom
telemetry signals are supported.
Wire Distance
Passive devices require no external power (e.g NV-
218A-PVD) whereas active devices do require external
power (e.g. NV-1672).
All measured distances include any coax in the path.
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.
Loop Resistance per 300m (1000ft)
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
Wire distances are limited to the minimum of
:
POWER DISTANCE - the power loss along the wire
from the Power Supply Cable Integrator Hub out to the
camera,
- and -
VIDEO DISTANCE - the video signal distance limit from
camera to the video receiver, and is dependent on the
type of receiver used.

Power Distance
Wire distance between the Power Supply Cable Inte-
grator and the camera is dependent on the camera’s
current draw. Please refer to the Power Distance Guide
below.
