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, 24 VAC output, or LINE voltage output. Additionally they can also 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 left and right automatically.

LOCKOUTS

Switcher/controller system ability to restrict access to certain system functions/features. The Allegiant

system modes of lockouts are:

•By operator level, allowing a higher priority level operator to lockout 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 phased 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, there can be multiple preset scenes 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 a year.

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.

VersAlarm

A flexible system of configuring alarms via the optional LTC 8059/00 MCS for Windows or the

LTC 8850/00 GUI software. Multiple groups of monitors can be programmed to respond to alarm

conditions in various ways. Additionally, each alarm may call up 1 to 4 cameras with user-selectable remote

operations. Alarm video may also be programmed to display user-defined alarm titles on the monitor overlay

display rather than the usual camera titles.
