Driver Specific settings

Identity: This parameter selects the ID of the camera that is connected to the video input.
Note! A separate program must be used to assign the ID to each individual unit.
Movement Limits These limits indicate the end positions in all directions; i.e. left, right, up and down. The limits will assure that the dome is kept within certain bounds.
Focus, Time: The maximum time for a focus move, used when you click the ends of the relative focus bar. If you click closer to the center the time will be scaled to reflect this i.e. the further from the center you click the longer the time used, also affects the "rfocus" cgi-command.
Iris, Time: The maximum time for a iris move, used when you click the ends of the relative iris bar. If you click closer to the center the time will be scaled to reflect this i.e. the further from the center you click the longer the time used, also affects the "riris" cgi-command.
