The LTC 8800 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.

Functions
General Construction
The LTC 8800 Series provide versatile modular
construction, accommodating up to 256 camera inputs, 64
monitor outputs, 32 keyboards, 1024 alarm points, a
computer interface port, and a logging printer port.

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 SalvoSwitching capability,
where any number of system monitors may be selected to
switch as a group. Using the optional LTC 8059/00 master
control software package, sequences can be made to
activate and deactivate automatically based upon the time
of day and the day of the week.
Camera Control
The LTC 8800 Series support variable speed operation
and full programming access for AutoDome and
AutoDome Easy II Series cameras. In addition, on-site
receiver/drivers are available to provide operator control
of pan, tilt, zoom, pre-positions, auxiliaries, auto-pan, and
random scan functions when used with conventional pan/
tilt devices. An integral local test function is also a
standard feature.
The LTC 8800 Series include an impressive user-based
priority system and a series of programmable lockout
tables to limit operator access of remotely controlled
devices. Operators can restrict control from lower priority
operators either manually or automatically. When enabled
to operate automatically, a built-in time-out period is user
programmable.

When combined with an LTC 8016 Allegiant Bilinx Data
Interface unit, these switcher/controllers support
operations using Bilinx communication. With Bilinx, PTZ
control is accomplished using a bidirectional
communication protocol embedded in the video signal of
Bosch Dinion, AutoDome, and AutoDome Easy II 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.
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 include the ability to combine any or all the
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.
