Why Use Preset Positions?
Defined preset positions can be used for making the PTZ camera automatically go to particular preset
positions when particular events occur, and for specifying PTZ patrolling schemes.
Defined preset positions will also become selectable in NetGuard/NetGuard-EVS, allowing users of these
applications to move the PTZ camera to the preset positions.

Absolute and Relative Positioning PTZ Cameras
Your configuration options depend on whether the PTZ camera in question is of the absolute positioning or
relative positioning kind:
•
Absolute:
For an absolute positioning PTZ camera, you are able to define up to 50 preset
positions.
You define a preset position by moving the PTZ camera to the required position with the controls in
the
PTZ View
section, then naming the position in the window's
Preset Positions
section.
•
Relative:
For a relative positioning PTZ camera, the number of preset positions will depend on the
camera/video encoder and PTZ driver used.
For some relative positioning PTZ cameras you will only be able to use preset positions defined on
the camera/video encoder itself (when this is the case, the preset positions are typically defined
through the camera/video server's “built-in” web page).
For relative positioning PTZ cameras allowing definition of preset positions through the NetDVR
system, you define a preset position by moving the PTZ camera to the required position with the
controls in the
PTZ View
section, then naming the position in the window's
Preset Positions
section.

How to Define a Preset Position
To define a preset position, do the following:
Note:
Some PTZ cameras of the relative positioning kind do not allow you to define preset positions as
described in the following; for such cameras, you should define preset positions on the camera/video
encoder itself.
1. First use the controls in the
PTZ Preset Positions for [Device Name] [Camera Name]
window's
PTZ
View
section to move the PTZ camera to the required position.
2. Having moved the PTZ camera to the required position, select an undefined item (may be labeled
Undefined
or with a position number) in the
Preset Positions
section's list of preset position names,
and click the
Set Position
button to define a name for the preset position.
For detailed information about the functionality of
PTZ Preset Positions for [Device Name] [Camera
Name]
window—such as the ability to test your preset positions, the ability to combine preset
positions with events, or the ability to use preset positions in PTZ patrolling schemes—see
Preset
Positions for [Device Name] [Camera Name]
window's sections in the following.
You are able to define up to 50 preset positions.
