Introduction

What is UTP?

UTP (Unbalanced Twisted Pair) is a new way of transmitting CCTC signal on ordinarylow-cost CAT 5 type data cables using low-cost Baluns (Balance Unbalance)

Why UTP?

Most new commercial (and even residential) building developments are installing CAT 5data ‘’backbones’’ as standard for building management systems. These can be integrated TCP/IP or standard protocols (Eg: LonWorks). If there is spare unused cabling UTP CCTV can use existing installations.Cat 5 cable is significantly cheaper than traditional RG59 and can fit far moreconductors into a smaller space.This can be an advantage when duct/riser space is limited, particularly in older buildings.

UTP Limitations

Base-band only (not for CATV)Active units do not support“ up-the-coax” P/T/Z controlsNot “broadcast” quality (>800 lines)Distance limited to 1200 meters, point-to-point

GE Security

Basic product type:

There are two basic types of UTP transceivers :-

Passive and Active

These can be used in one of the following three ways

depending on distance and type of cable used

Passive Active


GE Security

Passive to Passive (400M Cat5)

Passive is the simplest type of UTP Balun

It does not need an external power source, but does have distance limitations

Passive Tx/Rx are always transceivers, so unitscan be used at either end of the system


GE Security

Passive to Active (800M Cat5)

Passive to Active has the advantage of extended range (800M), plus it does not need external power down at the camera end

The Active receivers can be individually specified and powered or utilise rack mount hubs for easy installation


GE Security

Active to Active (1.2km Cat5)

Active to Active has the advantage of of super extended range (1200M), Active receivers offer extra noise immunity and surge protection

Active transmitters and receivers need 12Vdc at camera and receiver ends to operate

Active transmitters have 3 position gain switch (L,M,H) and active receivers have a 5 position gain switch depending on cable length used.

First set the 5 position DIP switch on the receiver depending on cable length deployed

Meters (Cat 5)Position 1 = 0-200Position 2 = 200-500Position 3 = 500-800 Position 4 = 800-1100Position 5 = 1100-1500

Then, if necessary set the Transmitter gain to Low, Medium or High to achieve a 1 volt Pk to Pk video signal
