The presets are designed to move the head of pan-tilt cameras to a fixed position. In order to use this functionality, you must first define the positions. You can make presets in the PTZ-menu in the Foscam App:
1. Turn the camera in the position of which you want to make a preset. Click the star icon and save the location as a preset.
2. In the preset-menu you will find screenshots of the saved preset locations. Click on a screenshot to let the camera turn to the preset location.
