Macro Capabilities
The LTC 8900 system provides powerful macro
capabilities. Macros can be activated using Allegiant
Series system keyboards, timed event functions, and
alarm activations.
Alarm Capabilities
The LTC 8540/00 alarm interface unit allows external
contact closure or logic level input to automatically
display cameras on a monitor or group of monitors. The
supplied PC software includes the ability to combine
multiple alarm operating modes within the same system.
Alarm video may be selected to reset either manually or
automatically. In addition, one can customize a 16-
character alarm titles to designate the specific alarm
condition.
System Operation
System operation and programming is accomplished using
a full-function, ergonomically designed keyboard. Up to
120 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.
Programming/Software Capabilities
The LTC 8900 Series includes a black outlined 48-
character on-screen display for time/date, camera
number, camera ID (16 or 40 characters), and monitor (12
characters) or status information. A user selectable option
provides the ability to display a third line of on-screen
text. This third line can be configured to display up to 24
additional camera title characters (40 characters total) or
a 12-character monitor title.
The on-screen display is also user selectable to operate in
"6-digit Camera ID" mode. When enabled, 2-digit "site
numbers" are displayed in addition to the 4-digit camera
number. The 2-digit site number feature is especially
useful when groups of cameras are located in separate
buildings, floors, or other common areas.
Over 1,000 characters covering a multitude of languages,
(including several hundred Chinese symbols) are available
to help program camera ID and monitor titles. Using the
supplied PC software, enhanced programming and
switching features can be obtained. A user friendly
spreadsheet format allows one to easily enter/change
camera titles, operator names, timed events (128), system
parameters, camera sequences, lockouts, and advanced
alarm response programming. The software also provides
the ability to enable an on-screen indicator for easy
identification of controllable cameras. Another useful
feature of the software is its ability to store or print (in
real-time) programming information, system events,
alarms, switching functions, sequence events, keyboard
actions, and video loss information.
Expansion Capabilities
The LTC 8900 Series can serve as the Master or Slave
Switcher in a SatelliteSwitch
®
configuration. This
innovative SatelliteSwitch feature enables a single
LTC 8900 system to communicate with remotely located
Satellite systems. Any Allegiant system can serve as a
remote Satellite Switcher. This powerful feature permits
the design of large distributed type systems. The main
control site can view and control local cameras as well as
cameras located at any of the remotely distributed
Satellite sites. The Satellite sites can view and control
only cameras associated with their local site. When used
in this type of configuration, the main LTC 8900 system
can access up to 256 Satellite sites.
