2. Introduction What is UTP?
UTP (Unbalanced Twisted Pair) is a new way of transmitting CCTC signal on ordinary
low-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 5
data ‘’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 more
conductors into a smaller space.
This can be an advantage when duct/riser space is limited, particularly in older buildings.

3. Benefits of UTP Immunity to noise Long distances (Over 1km)
Easy wire installation
Multiple video signals in the same bundle
RS-422/RS-485 in the same bundle
12VDC/24VAC in the same bundle
Lower cabling costs
Space saving

4. Noise Immunity Benefits
Better interference immunity from:
Neighboring cables/pairs
Fluorescent lights
Industrial Transformers and Motors
Radio Transmitters

5. Noise Immunity
Better interference immunity because
of the ‘’twist’’ in a twisted pair cable:

6. Why UTP?
Take advantage of:
Structured Building Wiring
The telecom industry has developed a
GREAT system employing:
High density cables
Colour coded
Mass termination
Super low cost

7. Where to use UTP? Locations where overall cost is less:
Within or Between Bldgs
Old/Listed buildings
Elevators
Hospitals
Prisons
Casinos
Schools
Office Developments
Shopping Malls
Hotels/Resorts
Warehouses
Amusement Parks
Apartment Complexes
Parking Garages
Mass Transit Systems
Entry Gates
Traffic Control

Ethernet / IP Based Transmission

9. Comparisons: vs Coax UTP vs. Coax 100 cables RG-59 Coax 1,100 pairs
Category 3 UTP
100 pairs
Category 3 UTP

10. Comparisons: vs coax
Smaller conductors
More dense
More flexible
Colour coded
Superior interference immunity

11. Comparisons: vs coax
Surge suppression (built-in)
Active units w/built-in ground lifting
Active units w/built-in gain control
Long distances (up to 1.2 Km)
Low wire costs (sometimes it’s free!)
Use coax for short runs, under 100 meters

12. Comparisons: vs Fiber
Less complexity and special skills
needed for installation
Lower cable cost
Similar features with lower Tx/Rx cost
No power required (many cases)
No minimum bend radius issues
Lower cost termination tools &
test equipment
No dB loss calculations

13. Comparisons: Ethernet
Much longer distance (100 meter TCP/IP limit between camera and hub)
No limited bandwidth issues specified by IT managers
No “frame rate” comparison (all images are Real Time)
Analogue vs Digital
No picture degradation due to compression artifacts
Put the IP requirement at the head-end, not at the cameras

14. UTP Limitations
Base-band only (not for CATV)
Active units do not support“ up-the-coax” P/T/Z controls
Not “broadcast” quality (>800 lines)
Distance limited to 1200 meters, point-to-point
Remember!
Do NOT use SHIELDED wire
Do NOT use UN-TWISTED wire

15. Wire Types Bad Bad OK (300M max) OK (300M max) Excellent

18. There are two basic types of UTP transceivers :- Passive and Active
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

19. 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 units
can be used at either end of the system

20. 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. 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 = 0-200
Position 2 =
Position 3 =
Position 4 =
Position 5 =
Then, if necessary set the Transmitter gain to Low, Medium or High to achieve a 1 volt Pk to Pk video signal
