User manual AXIS 240Q

[. . . ] AXIS 240Q Video Server User's Manual About This Document This manual is intended for administrators and users of the AXIS 240Q Video Server, and is applicable for firmware release 4. 30. It includes instructions for using and managing the AXIS 240Q on your network. Previous experience of networking will be of use when installing and using this product. Some knowledge of UNIX or Linux-based systems would also be beneficial, for developing shell scripts and applications. [. . . ] Note that this is only available if the camera is fitted with a zoom lens. · the Iris bar - adjusts the brightness of the image Clicking on the bars themselves or on the arrows at the end of the bars will move the camera to a new position. The type of movement and the location of this new position depends on the type of PTZ driver. When controlling the camera using a relative PTZ driver (see the bars in the illustration above) the new position will be relative to the previous position, e. g. Clicking the bar further from the center results in a larger movement. AXIS 240Q - Pan Tilt Zoom In contrast, when using an absolute driver, each position on the bar (see right) represents a defined position in the device's range of movement, with the center of the bar representing the point midway between the two extremes of movement. Clicking a position directly on the bar moves the camera directly to the new position in one smooth movement. Clicking on the arrows at the ends of a bar causes a stepped, incremental change. Using CGI links to control PTZ devices User-defined CGI links on the Live View page can be used to issue HTTP API requests, e. g. These links are configured in the Live View Layout settings, see page 8. PTZ Control Modes The PTZ device can also be controlled using click-in-image movement, which has two different types of navigation; Center and Joystick. Center mode means that when clicking in the image, the camera view will center on the absolute position that was clicked. By clicking and holding the mouse button down in the image, the PTZ device moves the camera in that direction, relative to the center of the image. The further from the center the image is clicked, the greater the movement. Control Panel The focus and iris (image brightness) can be adjusted manually by using the control bars, or they can be set for automatic adjustment, by clicking the Auto iris and Auto focus buttons. To access the Auto iris and Auto focus buttons, click on the Control panel button. The menu to the right will then appear in the upper left hand corner of the screen. There are also driver specific shortcuts that can appear in the Control Panel. In the screen to the right, a driver has been installed that brings up the Wiper shortcut button, which allows the user to configure and use a windshield wiping action with the AXIS 240Q. 31 32 AXIS 240Q - Pan Tilt Zoom Preset Positions Also available with many PTZ devices are Preset positions. These presets are selected from the drop-down Source list on the Live View page and will move and/or zoom the camera to a pre-defined position, i. e. Events can also be configured to go to preset positions when triggered. For information on setting up preset positions, please see Preset Positions, on page 29 and the online help. Guard Tour A guard tour moves between chosen Preset Positions, one-by-one, in a pre-determined order or randomly, and for configurable time periods. Unlike the Sequence Mode, which is a viewing application under Live View Config (see Live View Config, on page 19), the guard tour sequence will keep running after the user has logged off or closed the Web browser. Advanced Device Settings - The device settings window is for driver specific settings, so the appearance of this window can vary depending on the driver installed.
