To the extent supported by a given ONVIF camera model, Nx Witness provides convenient PTZ controls when a camera is in Live mode and also on fish-eye cameras and screenshots.

For the most commonly-used camera models that support ONVIF Absolute Move, the following features are also available:

•Saving and Restoring PTZ Positions

•Setting Up PTZ Tours

When PTZ requirements are met and enabled, the PTZ icon will display on the corresponding camera item.

Note: N ative PTZ camera presets (those that are configured on the camera web page) can be ignored in favor of Nx Witness settings by checking the Disable native presets, use system presets instead box in the Camera Settings -> Expert tab.

Depending on the camera model, one of the following modes is available when you click on the PTZ icon .

Simple (Zoom only) – As shown in the image below, only the + and - buttons are available to zoom in and out.

Regular (Zoom and Point) – U se the + and - buttons to zoom in and out. When there is a center circle as shown below, you can use it to click-and-drag the center of the image to the desired position.

Extended (Zoom, Point and additional features) – Requires ONVIF Absolute Move support by the camera and custom product integration. Allows zooming, repositioning, and the following additional controls:

•Click anywhere in the field of view to re-center at that position.
