ACTIVE CCTV RECEIVER HUB, 16-PORT
2. Introduction
2.1 Overview
The Active CCTV Receiver Hub provides centralized cabling for medium and large
CCTV installations via copper twisted pair. Typical installations include CCTV
cameras, DVRs, monitors, switches, multiplexors, and other CCTV equipment.
The hub features automatic gain control for picture brightness, sharpness, and
contrast, reducing on-site service calls. It supports distances up to 4500 ft.
(1371.6 m) via Category 5 twisted-pair cable when used with a passive CCTV balun
(part number IC440A, IC444A, IC451A, or IC452A) at the camera end.
The hub automatically adjusts the brightness, sharpness, and color intensity of the
video signal based on the actual cable conditions such as cable grade, distance, and
environmental effects on the cable. Once installed, you don’t have to go on-site to
check the video signal. Any further enhancements to the image may be made at
the camera, monitor, multiplexor, or DVR. The hub requires a floating 24-VAC,
40-VA power transformer (included) and connects directly to the DVR or CCTV
multiplexor.
Mount the hub in a rack, on a wall, or on the desktop. It features ground-loop
blocking for secure data transmissions. Diagnostic LEDs provide instant status
information.
Two models (IC454A and IC455A) are shown in Figures 2-1 through 2-3. The
IC454A features UTP on both input and output for installation in remote telecom
or wiring rooms. The IC454AE is the same as the IC454A, except that it has a
240-VAC power supply. The IC455A features UTP on the input and coax on the
output for installation next to the central monitoring (DVR or multiplexor)
equipment. The IC455AE is the same as the IC455A, except that it has a 240-VAC
power supply.
