System Q BAL316 Manual

BAL316 - 16ch Rack-mount Passive Video Balun
Transmit Video Down CAT5 Up To 200M!
The BAL316 sixteen-way passive video balun allows transmission of real-time monochrome
or colour video over Unshielded Twisted Pair (UTP) CAT5. All types of composite signal are
supported. A balun is required at both ends of the cable run and the CAT5 can be connected
via an RJ45 connector or via the appropriate connection on the terminal block. On the unit
used as the receiver the output is via the BNC connector. Full motion CCTV video will work on
these units up to 200mtrs. These units employ exceptional interference rejection with built-in
transient protection avoiding damaging voltage spike problems. These units do not require
any external power.
Co-axial cables are classed as an "unbalanced" mode of transmission and CAT5 twisted pair is
known as a balanced mode. In this balanced mode, the two cores carrying the video signal
are balanced to a particular reference point and the cable twists enable a uniform rejection of
interference, e ectively cancelling it out. To produce an unbalanced signal
standing for BALanced to UNbalanced.
Baluns come in two distinct groups.
up to distances of about 500mtrs although if you are using baluns to send video signals back
to multiplexers, quads and DVRs it is recommended not to use passive baluns over 200mtrs.
Active baluns require power for their "active" circuitry and can send video signals up to 2km
down low-cost CAT5 cable. Most baluns do not allow you to send power down the CAT5 cable
you will still need to power the camera
so
What's In A Balun?
Baluns contain small signal transformers that are specially tuned to match the cables
impedance and convert the unbalanced signal to a balanced one and vice versa. Passive
baluns just have the transformers and very little else in them. Active baluns have extra
electronic circuits used to amplify the signals helping prevent losses and also ltering out
unwanted noise.
The Advantage Of Using CAT5 Cable
CAT5 cable allows a tremendously exible way to install and distribute CCTV signals around
buildings and between locations. If for example you have two buildings 200mtrs apart you
could use one CAT5 cable to run 4 CCTV images from one building to another by using two
Passive baluns require no power to operate and work
locally or run another separate cable for power.
