2.16 VIDEO SCAN SEQUENCES
A Scan Sequence is a list of camera selections. This camera list, or scan sequence, is
used to automatically display every camera in the sequence on a specific monitor. Each
camera selection will remain displayed for a duration defined by the 'Dwell Time' setting
of each scan sequence.
When the scan sequence reaches its end, it wraps back around and starts again,
creating an endless sequence of pre-defined camera selections.
A scan sequence can have up to 99 separate camera selections (called Entries). A total
of 999 separate scan sequences can be created for use within the video system.
When required, one of the several scan sequences can be used on a monitor. When the
one scan sequence is run, on two or more monitors (at the same time), the same
camera selections are displayed, at the same time, on the monitors (synchronized).
Note:
Camera selections or entries in scan sequences
can (within the limitations of source grouping for that
monitor) be displayed in any order as desired.
2.16.1 Guard
tours
Scan sequences that do not wrap back around are called guard tours. When a guard
tour is executed, every camera entry in the sequence gets selected once only. When the
end of the sequence is reached, the last camera selection will remain displayed on the
monitor.
2.17 MACRO SEQUENCES
A macro sequence is a stored sequence of keyboard key presses. When required,
these macros can be PLAYED BACK to automatically control the video system.
Any action or series of actions can be stored as a macro sequence. Macros are usually
directly assigned to external alarm inputs or other system alarm conditions, and
executed whenever that alarm condition occurs.
