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. [. . . ] Preset positions can be selected in Live View, from events and in Sequence mode. One position can be set as the Home position, which is readily accessible by clicking in the box beside Use current position as Home. The position's name will then have (H) added, e. g. Office Entrance (H). 30 AXIS 240Q - Pan Tilt Zoom PTZ Controls If the AXIS 240Q has been appropriately configured, the Live View page will display the controls available for the installed Pan Tilt Zoom (PTZ) device. The administrator can enable/disable the controls for specified users. Preset positions Video sources Tilt bar (relative) The exact controls shown depends on the make and model of PTZ device. Focus and Iris bars available as well, but the most common controls are; · the Pan bar - moves the camera to the right and left · the Tilt bar - tips the camera up and down · the Zoom bar - zooms the view in and out. 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. Joystick mode moves the camera in the direction of the mouse pointer. 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. The camera stops moving when the button is released. 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. [. . . ] The PEM-format is often used for representing an HTTPS certificate or certificate request. Ping - A small utility used for sending data packets to network resources to check that they are working and that the network is intact. Pre/post alarm image - The images from immediately before and after an alarm. Protocol - A special set of rules governing how two entities will communicate. [. . . ]
