Comelit SPTZ10IR Mode D'emploi page 11

BLC (Back Light Compensation)
If a bright backlight is present, the target in the picture may appear dark or as a silhouette. The
BLC function can enhance the target in the center of the picture; the dome uses the center of
the picture to adjust the iris. If there is a bright light source outside this area which tends to wash
out to white, the camera will adjust the iris so that the target in the sensitive area will be properly
exposed.
Ratio Speed
Intelligent pan and tilt speed is variable dependent on the zoom factor. When zooming in, the
speed will become slower and when zooming out, the speed will become faster.
Preset
Once the camera has been programmed with specific location presets, it can automatically move
to the predefined positions when presets are called from a PTZ controller or DVR.
Tour
The dome runs a Tour according to the specific presets which the user has programmed, in the
order they are set to run.
Power Off Memory
This feature allows the dome to resume its previous preset or status after power is restored. By
the default setting, the dome supports power up memory, which improves reliability and avoids
repeated settings of the previous parameters.
Park Action
If the dome is not operated within the user-set time, it will automatically run a specific mode
(Preset, Tour, etc.).
Multilanguage OSD Menu
The language used for the on screen menu can be set to one of several available languages -
English, Spanish etc.
