AXIS Q1755/-E - PTZ (Pan Tilt Zoom)
PTZ Controls
If the network camera has been appropriately configured, the Live View page displays the controls available for the installed
Pan Tilt Zoom (PTZ) device. The administrator can enable/disable the controls for specified users under System Options >
Security > Users > User List.
The controls shown depends on the PTZ device. 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 moves 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 is relative to
the previous position, for example, left of, below, or above. Clicking the bar further from the center results in a larger
movement.
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 an incremental change.
