Preset is a user-defined position of the camera‘s pan tilt and zoom settings. Creating camera presets in advance can allow it to go to the wanted monitoring positions easily.
Patrol means that you can specify the scanning route of the camera through a set of presets. The camera will scan according to the preset patrol speed and staying time.
