4-5-8-1 Basic Operation – Pan, Tilt, & Zoom
The user can control all connecting PTZ cameras directly from the vi ewer and run all
functions of the PTZ camera.
Pan and Tilt
The panning function of the PTZ camera enables the lens of the PTZ camera to move
in the horizontal direction, and the maximum movement range can up to 360 degree.
The tilting function of the PTZ camera enables the lens of the PTZ camera to move in
the vertical direction, and the maximum movement range can up to 180 degree. The
combination of the panning and tilting functions allows the user to monitor almost the
entire 3-dimension horizon. To control the PTZ camera from the viewer, see the
following steps:
Figure 4-27 The Panning and tilting function of the PTZ camera
1. Refer to section 4-6 ‘ Time Slider ’ to show the Time Slider and click the PTZ
mode.
TIP: Press the hot key ‘ O ’ to toggle the PTZ mode
and the normal mode.
2.
Move the mouse to the center of the viewer. Hold the left key of the mouse and
move the mouse to the preferred direction. As the mouse moves, a red arrow line
appears, and the image in the viewer moves synchronically. The length of the
arrow line is the moving distance of the mouse. When the mouse moves farther,
the line becomes longer, and the lens of the PTZ camera moves faster. On the
contrary, the lens of the PTZ camera moves slower. When the line lies in the
horizon, the PTZ camera is panning; when the line stretches vertically, the PTZ
camera is tilting. When the line is leaning, the PTZ camera runs the panning and
tilting functions simultaneously.
