Configuring The Line Lock Setting - American Dynamics SpeedDome Ultra VII Operator's Manual

Configuring the Line Lock Setting

Use the Line Lock setting to prevent vertical rolling or adjust the appearance of overlay text
on color monitors.
If you experience problems with vertical video rolling when switching multiple cameras to a
single monitor, enabling the Line Lock setting phase locks the video with the AC power line.
All cameras connected to the same power supply will be synchronized. This synchronization
prevents the video from rolling vertically when cameras are switched.
With the Line Lock disabled, the appearance of text displayed on color monitors may be
improved. However, the video will no longer be phase locked with the AC power line. Video
may roll vertically when switching between cameras.
Changing the Line Lock Setting
1. Select Pan/Tilt/Zoom/Sync Opts from the Dome Configuration Menu.
2. Move the highlight bar to Line Lock. Change the setting.
•
Select On to enable the line lock. This phase locks the video with the AC power line
