4.4 Saving and Using Camera Presets
A camera preset refers to pre-saved camera configurations. Each camera preset saves the
zooming level and direction of the camera.
If a camera supports pan, tilt, and zoom (PTZ) functions, you can create a maximum of nine
camera presets. Each camera preset saves the camera number, zooming level, and camera
direction. A camera preset remains valid until you delete it or change it.
Table 4-9 describes the features of camera presets.
