The LTC 8500 Series Allegiant Video Switcher/Control
Systems combine both switching and computer
technology to provide powerful performance and unique
system features for the security user. Offering full matrix
switching capability, these systems can be programmed to
display the video from any camera on any monitor, either
manually or via independent automatic switching
sequences.
The LTC 8500 Series provide versatile modular
construction accommodating up to 64 camera inputs, 8
monitor outputs, 8 keyboards, 128 alarm points, a
computer interface port, and a logging printer port.

Functions
Sequencing Capabilities
These systems can be programmed with up to 60
sequences which can be run independently of each other
in either a forward or reverse direction. Any of the
sequences can utilize the Salvo Switching capability
where any number of system monitors may be selected to
switch as a group. Using the optional LTC 8559/00 Master

Control Software package or LTC 8850/00 GUI Allegiant
Server, sequences can be made to activate and deactivate
automatically based upon the time of day and the day of
week.
Camera Control
On-site receiver/drivers permit operator control of pan,
tilt, zoom, multiple pre-positions, four auxiliaries, auto-
pan, and random scan. An integral local test function is
also a standard feature. The LTC 8500 Series also
supports variable speed operation and full programming
functions of AutoDome series dome cameras.

When combined with an LTC 8016 Allegiant Bilinx Data
Interface unit, these switchers/controllers support
operations using Bilinx communication. With Bilinx, PTZ
control is accomplished using a bi-directional
communication protocol embedded in the video signal of
Bosch Dinion and AutoDome

®

 CCTV cameras. In addition,

Bilinx uses the standard video cable to transmit alarm and
status messages from the cameras, providing superior
performance without the need for separate data
transmission cables.
Macro Capabilities
The LTC 8500 system provides powerful macro
capabilities. The macros can be activated using Allegiant
system keyboards, system time event functions, alarm
activations, and via special function icons in the
LTC 8850/00 GUI software.
Alarm Capabilities
With the addition of the LTC 8540/00 Series alarm
interface accessory unit, an external contact closure or
logic level can be used to automatically activate any
camera to be displayed. Any monitor or group of monitors
can be set to display cameras under alarm conditions. The
base system contains three built-in alarm response
modes: basic, auto-build, and sequence and display. In
addition to these three modes, the PC based software
packages now includes the ability to combine any or all
three standard modes within the same system. Alarm
video may be selected to reset either manually or
automatically. In addition, a 16-character alarm title can
be selected to appear instead of the camera title during
alarm conditions.
System Operation
System operation and programming is accomplished using
a full-function, ergonomically designed keyboard. Up to 8
keyboards may be used in the system. Built-in operator
priority levels and the ability to restrict certain operators
from controlling designated functions provide maximum
flexibility.
