Specifying Timing Settings for a PTZ Patrol Scheme
Having selected a patrolling scheme in the Patrol scheme list, you are able to specify timing
settings for the patrol scheme:
1.
In the Stay at each position in the patrol schedule field, specify the number of seconds for
which the PTZ camera should stay at each preset position.
2.
In the Time for each PTZ camera movement to complete field, specify the number of
seconds required for the PTZ camera to move between preset positions.
In order not to generate false motion alarms, motion detection for the PTZ camera is
automatically disabled while the camera moves between two preset positions. After the
specified number of seconds, motion detection is automatically enabled again.
It is thus important that the camera is able to reach all of the patrolling scheme's preset
positions within the number of seconds you specify. If not, false motion is likely to be
detected.
Bear in mind that it takes longer for the PTZ camera to move between positions that are
located physically far apart (e.g. from an extreme left position to an extreme right
position) than between positions that are located physically close together.
3.
The total number of seconds between each preset position will be listed below the two
fields.

PTZ Patrolling Actions on Detected Motion
You are able to combine a PTZ patrol scheme with motion detection, so that when motion is
detected, the PTZ camera will pause its patrolling and remain at the position where motion was
detected for a specified period of time.
To use this feature, do the following:
1.
Select the Disable patrolling schedule if motion is detected check box.
2.
Select whether the PTZ camera should resume patrolling:
•
When a certain number of seconds has passed since first detection of motion,
regardless whether further motion is detected, or,
•
When a certain number of seconds has passed without further detection of motion
3.
Specify the required number of seconds for selected option.
Example: You may specify that the PTZ camera should go to the next preset position and
resume patrolling when 10 seconds has passed without detection of motion.
•
PTZ Scanning
PTZ scanning is supported on a few devices only. If your device supports PTZ scanning, the Setup
of PTZ Scanning section lets you enable PTZ scanning and select a PTZ scanning speed.
