AXIS 243Q Blade - 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 help issue HTTP API requests, for example,

PTZ commands. These links are configured in the Live View Layout settings, see The Live

View page,

on page 10.

PTZ control modes
The PTZ device can also be controlled using click-in-image movement, which has two

types of navigation - Center and Joystick.

The Center mode means that when clicking in the image, the camera view will center on

the absolute position that was clicked.

The Joy

stick 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.

Note:

There is also joystick support in AXIS Media Control (AMC).

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.

Note:

These buttons appear only if the PTZ driver installed supports them.

To access the Auto iris and Auto focus buttons, click 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 243Q

Blade.
