LTC 8600 Series
The LTC 8600 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 8600 Series provide versatile modular construction
accommodating up to 128-camera inputs, 16-monitor outputs,
16-keyboards, 512-alarm points, a computer interface port,
and a logging printer port.
Features
• 128 Camera by 16 Monitor Switching
• Modular Construction
• Powerful Alarm Handling Capabilities
• SalvoSwitching and SatelliteSwitch Capability
• PC Based Software Package Available
• Economical Single-Bay Design
Functions
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 8659/00 master control software package, or the
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.
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 8600 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 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 and AutoDome CCTV cameras. In
addition, Bilinx uses the standard video cable to trans mit alarm
and staus messages from the cameras, providing superior
performance without the need for separate data transmission
cables.
With the addition of the LTC 8540/00 Series alarm interface
accessory units, 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 &
display. In addition to these three modes, the PC based software
packages now includes VersAlarm - a new dimension in alarm
handling. VersAlarm has the ability to combine any or all of 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.
The LTC 8600 Series includes a black outlined 48-character on-
screen display for time-date, camera number, camera ID
(16-characters), an icon to identify controllable cameras, and
monitor (12-characters) or status information. Over 1000
characters are available when programming camera ID and
monitor titles. Utilizing a standard IBM1 compatible PC and the
optional LTC 8659/00 Master Control Software package or
LTC 8850/00 Graphical User Interface (GUI) software,
enhanced programming and switching features can be obtained.
A user-friendly spreadsheet format provides the ability to enter
camera titles, operator names, 64 timed events, change system
parameters, program camera sequences, install lockouts, and
access the advanced VersAlarm alarm handling screens with
speed and efficiency. The programmed information may then be
transferred into the Allegiant system, stored on disk, or printed
out directly from a printer connected to the PC.
The LTC 8850/00 Bosch GUI software is designed around an
intuitive graphic-based interface, the GUI provides high
performance programming, control and monitoring of all system
functions by using on-screen icons to reflect real time status of
the devices controlled by the system.
The LTC 8850/00 GUI software also provides the ability to
monitor system status events. System alarms, switching
functions, sequence events, keyboard actions, and video loss
information can be viewed in real time on the PC screen and,
if desired, logged to the PC hard drive.
The LTC 8600 Series contain a logging printer output port which
accepts a standard RS-232 serial printer. This provides a
permanent record of system status showing time and date of
changes such as: incoming alarms, acknowledgment of alarms,
loading of sequences, user log-on to keyboard, transfer of
system tables and sequences, video loss messages, and a
power up reset message. In addition, the printer can be used to
obtain a hard copy of the system's configuration tables and
sequences.
