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.

The LTC 8800 Series accessory products provide many optional
features to the base Allegiant switching systems. Accessory products include
keyboard extension kits, Allegiant Bilinx Data Interface unit, receiver/driver
units, switcher/followers, code merger units, the video ribbon cable and key-
board expansion units. All accessory products are designed to be installer
friendly and compatible throughout Allegiant series systems. See the Allegiant
Accessories datasheet.
