Introduction

GE Security Single-Channel Video-Power-Data Combiner-Transceivers combine video, camera power

and PTZ data over a single 4-pair UTP cable to simplify CCTV installations in structured wiring

environments. These units feature a passive transceiver that may be paired with other GE Security

single and multi-channel combiner-transceivers for distances up to 750 ft. (228 m), or with GE Security

multi-channel combiners and active UTP receivers to extend the video range up to 3,500 ft. (1,067 m).

They feature excellent crosstalk and noise immunity, which provides quality video up to the maximum

distance. They are compact in size, easy to install. The

GEC-VCR12V

includes a built-in 24 VAC to 12

VDC converter to power cameras.

These combiner-transceivers have an RJ-45 connector to connect to a standard Category 5 cable

along with set of break-out cables: one pair for power, one pair for PTZ data and an attached BNC

connector or a coax cable with BNC connector for video input.

The following model numbers are covered in this document:

• GEC-VCR

•

GEC-VPDBC

• GEC-VCR12V

Wiring Technical Notes

These technical notes should all be considered prior to installing these devices.

• Use point to point unshielded twisted pair wire 24-16 AWG (0, 5-1, 3 mm) stranded or solid,

Category 2 or better.

• The video signal may coexist in the same wire bundle as other video, telephone, data, control

signals, or low-voltage power. You can run GE Security video signals in or near electromagnetic

fields (in accordance with National Electrical Code, local or other local safety requirements).

• DO NOT USE SHIELDED TWISTED PAIR WIRE. Multi-pair (8 pair or more) wires with an overall shield

are fine.

• DO NOT USE UN-TWISTED WIRE.

• DO NOT place a transmit and a receive signal in the same wire bundle. It may cause interference.

• DO NOT send

Up-the-Coax

Pan/Tilt/Zoom signals through active (amplified) GE Security

transmitters or receivers. Passive GE Security transceivers can transmit video and

Up-the-Coax

P/T/Z control signals up to 750 ft. (228 m).

• We recommend using short 18 AWG solid wires for ground connections.

• GE Security VPD products follow the EIA/TIA 568 standard. There are two wire color-code

standards: EIA/TIA 568A and EIA/TIA 568B. Either standard can be used for making connections as

long as the RJ-45 jacks at both ends of each cable follow the same standard.

• Measure wire distance by:

1. Shorting the two conductors together at the far end, and measuring the loop-resistance

by an Ohmmeter.

2. Use the

Loop Resistance

table to calculate the distance.

• DO NOT connect coax cables longer than 100 ft. (30 M) to the BNC connectors of any GE Security

UTP equipment.

• All measured distances should include any coax cables in the path.

• Verify camera current requirement and wire resistance limits for the maximum distance that

power can travel. Use the

Power Distance Chart

to verify the wire distance.

• GE Security VPD products require Unshielded Twisted-Pair (UTP) wires Category 2 or better, 24

AWG (0,5 mm) or thicker.

Data

Video:

Connect the baseband Video signal output of the camera to the BNC connector of the GEC-VCR.

Data:

There is no data connection on the GEC-VCR.

Power:

Connect the power UTP pigtail (Black/Red) wires of the GEC-VCR to the power connector of the

camera.

Cat-5 Cable:

Connect the RJ-45 connector of the Cat-5 cable coming from the camera to the RJ-45

jack of the GEC-VCR. Make sure that the pin-outs of the RJ-45 connector match the pin-outs of the

GEC-VCR.
