Security Camera User Manual

AXIS 241QA/AXIS 241SA - 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 th

e 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 c

an be used to issue HTTP API requests, such

as PTZ commands. These links are configured in the Live View Layout settings; see page 9.

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 centers on the

absolute position that was clicked.

Joystick mode moves the camera in th

e 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 adj

usted 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 shortcu

ts 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

241QA/AXIS 241SA.
