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.

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

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
20 GE SecurityPresenter NameDate
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
21 GE SecurityPresenter NameDate
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
