Wrong pair of wires
Make sure the connections are secured
properly and wires are not broken or missing.
Verify that each video signal uses conductors
from the same twisted pair.
Scrambled picture Wrong polarity Check polarity on each pair of wires.
Make sure to match the corresponding
numbers on the detachable terminal block and
BNC connectors

Long stubs The transceiver devices must be used with
point to point connection of unshielded twisted
pair wires. Remove any extra branch of twisted
pair wires. Verify that there are no star
configurations.
Noisy picture Untwisted pair of wires Use twisted pair wires to avoid interference.
Dim picture Long wires
High gauge wires.
Use less than 6 feet of coax cable between the
transceiver device and the video source. UTP

Shielded wires Use unshielded twisted pair wires Cat 2-7 to
avoid impedance mismatch.

1. Introduction
The Vigitron Vi1004 is a passive 4-port hub that transmit or receive video or
data over unshielded twisted pair (UTP) wires, point-to-point, for distances up
to 1000 feet* (330 m). It also provides support for the “up the coax” PTZ
control signals.
This hub uses Category 2-7 twisted pair wires, is easy to install, cost
effective, and does not require power. It has built-in surge suppression to
protect video equipment against damaging voltage spikes. Its cross-talk and
noise immunity ensures quality video signals. The Vigitron passive hubs offer
quality video in a highly integrated and a cost-effective package. This HUB is
ideal for a wide variety of security and surveillance applications that require
medium-density CCTV systems.

4. Installation
4.1 Preparation:
Before getting started verify that you have the following items:
•Unshielded Twisted Pair (UTP) wires (24 AWG or better). Do not use untwisted wires since
it may result in interference and noisy picture. Do not use shielded twisted pair wires since
it may cause impedance mismatch.
•Verify that each video signal uses conductors from the same twisted pair.
•The transceiver devices must be used with point-to-point connection of unshielded twisted
pair wires. Any extra branch of twisted pair will cause ghost effect and poor quality video.
•Do not use more than 6 feet of coax cable between the transceiver devices and video
sources.
4.2 Transmitter side installation:
1. Choose the right mating transceivers (See table in section 2).
2. When a single transceiver is used, connect the video source (camera, etc.) through a coax
cable (less than 6 feet) or directly to the BNC video input of each transceiver. Connect one
end of the UTP wire to the terminal block of each transceiver. Connect the green GND wire
to chassis ground.
3. When a transceiver hub (i.e, Vi1004) is used, connect the video source (camera, etc.)
through a coax cable or directly to the BNC video input of each channel. Connect one end
of the UTP wire to the terminal block of the corresponding channel.
4.3 Receiver side installation:
1. Mount the hub near the monitors or DVRs using the VI0010 rack mount panel or by itself.
2. Connect the hub to the video equipment (monitors, VCRs, etc.) using the 2 feet coax
cables provided with the kit. Make sure the connections are secured properly.
3. Connect the other end of the UTP wire, to the hub’s detachable terminal block. Make sure
to match the corresponding numbers on the detachable terminal block and BNC
connectors.
4. If the picture is scrambled change the polarity of the twisted pair wires to the corresponding
terminal block.
