Term Definition
AUXILIARY An auxiliary is an additional function of the remote receiver/driver, which permits on/off control of outputs
available to the user. In the Allegiant system, four relay outputs are available, which can be configured for
contact closures, 24VAC output, or LINE voltage output. Additionally, they can be set to activate either
momentarily, or in a latching mode.
COMMAND SCRIPT A unique feature of the Allegiant system wherein a section of nonvolatile memory can be used to store
specialized factory programming. This program then provides custom features, not ordinarily obtainable.
DITHER A receiver/driver feature providing added protection to very low light level cameras, by periodically panning
a few degrees to the left and right automatically.
LOCKOUTS Switcher/controller system ability to restrict access to certain system functions/features. The Allegiant
system modes of lockout are:
By operator level, allowing a higher priority level operator to lock out lower level operators from
viewing or controlling specific cameras.
By MCS setups to:
1. Restrict operators/keyboards from viewing/accessing any camera.
2. Restrict operators/keyboards from controlling/accessing any pan/tilt.
3. Restrict operators from using certain keyboards.
4. Restrict operators/keyboards from accessing certain monitors.
LOGON, LOGOFF A selectable Allegiant feature requiring operators to enter a User number and optional password into the
keyboard prior to access.
MATRIX SWITCHING The ability of a switching system to display any camera on any monitor, or the same camera on all monitors.
PHASED CAMERAS These are properly integrated cameras, giving a roll-free video display when switching from one camera to
the next in a sequential switcher system. Phased cameras are the result of line-locked cameras powered
from the same AC power, externally synchronized, or vertically phase adjusted on cameras equipped with
this option.
PRE-POSITION The ability to store the position of a pan/tilt/zoom lens, so that the desired scene can later be automatically
recalled. With the Allegiant system, multiple preset scenes can be stored for each pan/tilt camera. For each
scene, the pan, tilt, zoom, and focus settings are stored.
SalvoSwitching The ability of the Allegiant system to switch multiple video monitors as a synchronized group. Since multiple
monitors switch together, multiple scenes of an area or zone are viewable before switching to the next area.
SEQUENCE A series of camera scenes that can be preprogrammed to switch automatically. The Allegiant system can
store up to 60 sequences, each one capable of having random camera order, individual camera dwell
times, and SalvoSwitching steps.
TIME EVENT An Allegiant system feature (available with the LTC 8059/00 MCS for Windows or the LTC 8850/00 GUI
software) enabling various system functions to periodically be activated automatically. Event functions
(monitor message broadcasts, sequence and switching operations, receiver/driver actions, message
printing, alarm settings, and execution of custom factory programming) can be stored in the system memory
for execution at a predetermined time. The task can be specified to begin on a specific year, month, day,
and time, and can repeat at intervals from every five minutes to yearly.
VERTICAL INTERVAL
SWITCHING
Camera to camera video switching during the vertical blanking interval of the video signal. This minimizes
visual switching disturbances such as rolling, jitter, video flashes, etc., and eliminates frame information loss
when used with video tape machines.
