PTZ Configuration and AutoTracking
79
Maximum Tracking Time
Defines the maximum time that a subject is tracked for by the PTZ camera. Even if a subject
is being tracked by the PTZ camera, the PTZ camera will stop auto tracking (and return to
the VCA home preset position if configured) if this time elapses.
Maximum Hold-on Time
If a subject is lost by the autotracking algorithm, or comes to rest (becomes stationary), this
defines the amount of time the PTZ camera will stay in that position trying to re-acquire the
subject before returning to the VCA home preset position. If the subject starts moving again,
or is reacquired, autotracking continues until the maximum tracking time (above) elapses.
Allow Manual Override (User Control)
When manual override is enabled, the auto-tracking algorithm will release control of the PTZ
and stop controlling the PTZ camera if a user sends a manual PTZ command. The auto-
tracking algorithm will reset when no user PTZ commands have been sent for the specified
period.
When manual override is disabled, all user PTZ commands will be ignored if auto-tracking is
in progress.
Note: In the case of autotracking, user PTZ commands refer to the PTZ commands sent
through the camera or encoder HTTP or web interface. Currently it's not possible to detect
commands sent directly on the RS-485/422/232 bus and user commands sent in this way
may cause undefined or erratic PTZ behavior if autotracking is also enabled.
Auto-tracking Initiation
PTZ autotracking can be initiated in three different ways:

Start tracking when any object is detected:
The auto-tracking will start automatically and track the first object detected by the
VCAsys tracking engine (normally from the VCA home preset position). The "Start
auto tracking when any selected rule triggered" checkbox should be
unchecked to
enable this mode.

Start tracking when an existing VCA rule is triggered:
The auto-tracking will start automatically when any one of the VCA rules in the
"selected rules" list is triggered. This provides a powerful way to filter out the objects
of interest that are selected for autotracking and exclude any other objects. The
"Start auto tracking when any selected rule triggered" checkbox should be
checked to
enable this mode and the rules that should initiate autotracking should be present in
the "selected rules" list on the right hand side.

Start tracking when initiated manually by the user (Manual Lay-on):
It is also possible for the user to manually initiate PTZ autotracking. This feature is
useful if the operator spots something of interest and would like the PTZ autotracking
to take over the job of tracking the subject automatically.
Manual lay-on can be achieved in two ways:

By selecting a target that is already being tracked by the VCA engine. In
this case the target will be highlighted with a bounding box on the user
display. Simply
double click the target while holding the shift key and
PTZ autotracking will be initiated on the selected target.
