Wire Type
The PVD system operates well with Category Unshielded Twisted-Pair
(UTP) wire, 24-22 AWG (0,5-0,6mm). NVT signals may reside near
electromagnetic fields (in accordance with National Electrical Code, and
other local safety requirements).
Low voltage camera power, video and RS-422 or RS485 may be sent
within same wire bundle as datacom signals not telecom.
Do NOT use shielded twisted-pair wire unless it is Category rated. Multi-
pair wire with an overall shield (6 or more pairs) is OK.
Do NOT use un-twisted wire.
Wire in underground conduit or wet locations must be polyethylene-
jacketed, gel-filled.
Do not run 24/28 VAC within same wire bundle with telecom or other
datacom signals.
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.
Measure Your Wire Distance
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.
Video Distance:
Recommended wire distances for best resolution is
shown in
Figure 1
. 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. See
Figure 2
.
Power-Video Fixed camera
single channel application
Power and Video at the Camera End
1. Connect the baseband Video signal output from the camera to the
male BNC on the NV-216A-PV or NV-218A-PVD.
2. Connect the camera’s Power input to the 18AWG Power wires on the
NV-216A-PV or NV-218A-PVD. Verify wire distance, camera load and
wire resistance limit for the maximum distance that Power can travel
using
Figure 3
.
3. Connect the 4-pair Cat-5 using the NV-216A-PV’s or NV-218A-PVD’s
8-pin RJ45 connector on the UTP run to the Equipment Room as
shown in
Figure 4
.
Connecting the Power-Video at the Equipment Room End
1.Connect the baseband Video input twisted pair to the screwless
terminals adjacent to the RJ45 connector of the NV-218A-PVD, or
using the 8-pin RJ45 connector on the NV-216A-PV or NV-218A-PVD
as shown in
Figure 4
.
2.Connect the baseband Video signal output from the BNC pigtail on the
NV-218A-PVD or the BNC of the NV-216A-PV directly to the Video
monitor, multiplexer, or DVR.
3. Connect Power via a Class II (SELV) low-voltage Power supply. NVT
recommends the use of 18AWG solid wire. NVT also recommends
Power supplies with individually floating outputs.
Power-Video-Data P/T/Z camera
single channel application
Connecting Power-Video-Data at the Camera End
1. Connect the baseband Video signal output from the camera to the Male
BNC pigtail connector on the NV-218A-PVD.
2. Connect the camera’s Power input to the screwless terminals marked
Power on the NV-218A-PVD. Verify wire distance, camera load and wire
resistance limit for the maximum distance that Power can travel using
Figure 3
.
3. If the camera supports P/T/Z telemetry over RS-422 or RS-485,
connect the camera’s Data terminals to the Data screwless terminals
on the NV-218A-PVD.
4. Connect the 4-pair Cat-5 using the 8-pin RJ45 connector on the UTP run
to the Control end as shown in
Figure 4
.
Connecting the Power-Video-Data at the Equipment Room
1. Connect the 4-pair Cat-5 from the camera end to the RJ45 connector
on the NV-218A-PVD.
2. Connect the baseband Video signal output from the BNC pigtail on the
NV-218A-PVD directly to the Video monitor, multiplexer or DVR.
3. Connect the control equipment data port to the screwless terminals
marked data on the NV-218A-PVD.
4. Connect the Power screwless terminals to a Class II (SELV) low-voltage
Power supply. NVT recommends the use of 18AWG solid wire. NVT also
recommends Power supplies with individually floating outputs.
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 120° 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 - 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.
TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO
NOT REMOVE COVER OR BACK. NO USER
SERVICEABLE PARTS INSIDE. REFER SERVICING

Camera Power Distance:
Different cameras draw different
amounts of current. It is important to make sure that the
voltage-drop on the wire allows sufficient voltage for the
camera to operate properly. A camera voltage of 21VAC or
greater is usually acceptable.
