Receiver Hub Installation Guide
Models NV-8PS42-PVD, NV-16PS42-PVD and NV-32PS42-PVD
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 polarized or
grounding-type plug. A polarized 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
replacement 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
specified 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.
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 environment
where the operating ambient temperature exceeds 122° F
(50° C). 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 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 - Use only a Certified power cord and plug
(coupler / mains) assemblies for location installed.
WARNING - Power cord is regarded as main
disconnect.
WARNING - Class 1 apparatus shall be connected to
a mains socket outlet with a protective earthing
connection.
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. Model NV-32PS42-PVD requires a
minimum of 2.5 in. (63.5mm) unrestricted open air space
on each side of the unit.
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.

Camera
The NVT Power Supply StubEQ™ Receiver Hub is an active
(amplified) hub that allows the transmission of real-time
monochrome or color video for distances up to 1,500ft (460m)
using Cat5 or better unshielded twisted-pair (UTP) wire. Its
2-band equalizer continuously and automatically compensates
for cable attenuation and ground loops, independent of the video
content. The 1U hub is equipped with multi-stage transient
protection.
The hub combines a 28VAC power supply with video and
telemetry data, for 8 to 32 cameras, all over UTP wire. Designed
for installation in 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 or NV-226J-PV (power & video only) or
the NV-218A-PVD (power, video, and telemetry data) transceiver
via an RJ45 connector and a single 4-pair cable. Control/MDF
connections are also RJ45, with BNC video outputs for the DVR,
matrix switcher, etc. Telemetry connections, if required, are
supported via an RJ45 connector for each group of four camera
channels.
The NV-8PS42 supports up to 8 cameras at up to 1 amp per
camera, and delivers two BNC outputs per channel. The
NV-16PS42 supports up to 16 cameras at up to 1 amp per
camera, and delivers two BNC outputs per channel. The NV-
32PS42 supports up to 32 cameras at up to 500mA per camera,
and delivers one BNC output per channel.
Wire Type
The Power Supply StubEQ
TM
Receiver operates well with Category 5 or
better Unshielded Twisted-Pair (UTP) wire, 24-22 AWG (0,5-0,64mm).
The video signal may co-exist in the same cable tray 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 individually shielded twisted pair. Overall shielded,
multi-pair (6pr +) Cat5 is OK.
Do NOT use un-twisted wire.
Wire in underground conduit or wet locations must be
polyethelyne-jacketed, gel-filled.
Wire in plenum environments must be plenum-rated, per local
codes.
RS-422 and RS-485 Pan/Tilt/Zoom telemetry signals are
supported.
Wire Distance
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. 1000 feet (300m) of 24 AWG
(0.53mm) wire is 52 ohms; 23 AWG (0.57mm) is 42 ohms.
Wire distances are limited to the minimum of:
POWER DISTANCE - the power loss along the wire from the
Power Supply Passive Receiver Hub out to the camera,
- or the -
VIDEO DISTANCE - the video signal distance limit from camera to
the Power Supply StubEQ
TM
Receiver, not to exceed 1500ft (460m).
Connecting PVD at the Camera End
Use the NV-216A-PV for fixed cameras, or the NV-218A-PVD for
fixed or P/T/Z cameras. Install per the instructions that come with
the transmitting device using 4-pair wire and RJ45 connectors.
NVT recommends the use of factory-crimped RJ45 patch cables
rather than unreliable field-crimped RJ45s to connect between the
NVT device and an adjacent female RJ45 jack. Wiring pinouts are:
Connecting PVD at the Power Supply
StubEQ
TM
Receiver Hub
CAUTION: Before applying power set voltage selection
switch to proper input line voltage.
Bring the 4-pair PVD cable from each camera back to the location
of the Power Supply StubEQ
TM
Receiver. NVT recommends that an
RJ45 Patch Panel be used here in conjunction with RJ45 patch-
cords. Use of these EIA/TIA 568B compliant practices allows for
easy testing with an RJ45 (LAN) tester, as well as moves and
changes.
Connect the PVD signals into ports on the front of the Power Supply
StubEQ
TM
Receiver Hub.
Connect the IEC cable between the power inlet and a grounded
electrical outlet. Switch on the power switch and observe the blue
power LED.
Video Distance
Recommended wire distances for best resolution is shown in
chart below. Wire distance between the camera and the Power
Supply StubEQ
TM
Receiver Hub should not exceed these
recommendations:
Power Distance
Wire distance between the Power Supply StubEQ
