Black Box IC454A, IC454AE, IC455A, IC455AE, IC453A Specifications
1
Balun transmits video
signals up to 5000 feet
(1524 m).
Balun also acts as a
surge suppressor.
Hubs support
distances up to
4500 feet (1371.6 m).
Select from two
UTP/UTP or UTP/Coax
hubs.
Works with our
passive baluns.
Automatically adjusts
the video signal based
on actual cable
conditions.
U
se unshielded twisted-pair
(UTP) cable instead of the more
expensive coaxial cable to
connect CCTV cameras, monitors,
DVR, switches, multiplexors, and
other CCTV equipment together.
You’ll need an Active CCTV
Receiver Balun (IC453A) or
16-Port Hub (IC454A, IC454AE,
IC455A, or IC455AE) at one end
of the connection and a passive
CCTV balun (IC440A , IC444A,
IC451A, or IC452A) at the camera
end.
Using the balun, CCTV video
signals can be transmitted up to
5000 feet (1524 m) over Category 5
UTP cable. With the hub, video
signals can travel up to 4500 feet
(1371.6 m) via CAT5 cable.
Picture brightness, sharpness,
and contrast are all supported
thanks to the balun or hub’s
Automatic Gain Control (AGC)
feature. The balun or hub
automatically adjusts these video
signal characteristics based on
Connect CCTV security and
surveillance equipment
together with Category 5
unshielded twisted-pair cable.

actual cable conditions (cable
grade, distance, and environmental effects on the cable).
This reduces on-site service calls,
since you can adjust the picture
at the camera, monitor, multiplexor, or DVR end.
For the balun, you’ll need a
24-volt, 2-watt AC or DC power
supply (not included). The hub
includes a 24-VAC, 40-VA power
supply.
The balun and hub also
provide Ground Loop Blocking
(GLB) to give you secure, reliable,
and stable data transmission and
images. The balun attaches
directly to the CCTV receiver
equipment. And a VELCRO
®
pad
is included for optional surface
mounting. After it’s installed, the
balun or hub operates
unattended. The balun also
provides screw terminals with
built-in strain relief, surge
protection, an automatically resetting fuse, and diagnostic LEDs.
For larger installations, chose
the 16-Port Active CCTV Receiver
Hub (IC454A, IC454AE, IC455A,
IC455AE). It lets you cable your
system with Category 5 UTP from
a central location. Installations
include CCTV cameras, DVRs,
monitors, switches, multiplexors,
and other CCTV equipment.
The IC454A has UTP screw
terminals on both input and output
ports, and it uses a 110-VAC
power supply. The IC454AE is the
same as the IC454A, except that it
uses a 240-VAC power supply.
The IC455A and IC455AE have
UTP screw terminals on the input
port and coax cable on the output
port. One model (IC455A) uses a
110-VAC power supply and the
other (IC455AE) uses a 240-VAC
power supply
The hub mounts in a rack or
on a wall (using the attached
mounting brackets), or on the
desktop (via the included rubber
feet).
