and the order for the pattern.

PTZ Keyboard or DVR with RS-485 controls. This speed dome supports optical and
digital zoom capabilities.
•Focus Control
The PTZ-2201 system defaults to Auto-Focus. When the lens changes to zoom in or
out, the lens will automatically adjust the focus according to the objects in the center
of the camera’s view. The user can manually adjust the focus of the camera by using a
PTZ Keyboard with “Far/Near” buttons or with DVR using the Far/Near commands
through RS-485 control. Once the joystick is manipulated to move the camera, the
Auto-Focus will be re-enabled again.

time

amount of light that is allowed into the image sensor of the camera. User may adjust
the Iris by a PTZ Controller keyboard using the “Open/Close” key or through a DVR
with RS-485 PTZ Controls. User can reassume Auto-Iris control by simply moving
the camera again using the joystick.
