Disconnected Video Source
Any problem with the camera or video source is indicated by a blank display. This may
indicate a break in the signal transmission or the cable, and any such incident should be
immediately referred to your system administrator.
Positional Control of the Video Source
Video cameras supporting Pan Tilt and Zoom (PTZ) are connected and controlled directly
from the server’s ports.
A PTZ-configured video source is automatically displayed with Pan, Tilt and Zoom bars, as
shown in the illustration below:
Notes: •The AXIS 250S can control a range of relative and absolute PTZ devices via the Web interface, or
via a third-party application. The positioning tools provided depend on the selected PTZ device.
Other functions, not shown in the illustration, may also be available.
•PTZ controls can be disabled in the Live View layout settings and may be unavailable in the user
interface.
•Clicking anywhere on a toolbar’s gradient allows for a “smooth” PTZ adjustment; whereas click-
ing on the left or right arrows causes a stepped incremental change.
