PTZ PRESETS

A preset is a user-defined camera position that uses PTZ and focus commands. (The camera’s autofocus option must be turned off to use presets.) The unit’s preset range is 0 to 255. For information about the number of presets supported by a given camera, refer to the documentation supplied with the camera.

Programming a Preset

1.Click a camera pane, and then click PTZ .

2.Click the Move , ZOOM, and FOCUS buttons to position, zoom, and focus the camera.

3.Store the preset to a memory location.

a.Click SET. The camera is now in the programming mode.

b.Click the numbers on the keypad for the preset memory location.

c.Click PRESET. The camera’s position, zoom factor, and focus setting are stored to the memory location.

4.Repeat the previous steps (as necessary) to create additional presets for the same camera.

5.Click SET to exit the programming mode.

6.Verify that you can activate the preset.

a.Click the Move buttons .

b.If you changed the camera’s zoom or focus, verify that the settings are different than the preset settings, and then click PRESET. The camera performs the programmed preset.

Preset Tours

A preset tour allows a camera to move through a programmed sequence of PTZ presets. The DX4700/DX4800 tour advances sequentially through presets 1 to 16. There is approximately a four-second pause between the end of the current preset and the start of the next preset. If the presets are programmed sequentially (1, 2, 3, 4, and so forth), the time period between presets is brief. If any presets are not programmed sequentially, the time period between the end of the current preset and the start of the next can be longer, because the system still accounts for the four- second interval for the unprogrammed preset memory location. For example, if presets 1 and 2 are programmed and presets 3 to 16 are not programmed, the system waits approximately 56 seconds (14 unprogrammed presets at four seconds each) before starting preset 1.

A preset tour operates continuously until another PTZ control action is performed. At least one PTZ preset must be set in order to create a preset tour.

To activate a preset tour, click the PRESET button without entering a preset number. This activates a preset tour for all PTZ-enabled cameras.

Clearing a Preset
