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 to
prevent video rolling.
• Select Off to disable the line lock. This stops the phase lock, but may improve the
appearance of text displayed on color monitors.
The default setting is Off.
3. Select Exit. The Dome Configuration Menu appears.
Configuring the Freeze Frame Setting
If you need to maintain a static image when calling automatic functions, such as presets or
patterns, use the Freeze Frame setting. This prevents the display of the dome movement and
lens adjustments from being displayed on-screen while the preset or pattern is being sought.
When the Freeze Frame setting is enabled, the scene currently displayed on the monitor will be
preserved (frozen) on-screen until the pattern or preset is ready for display. The image then
switches smoothly to the new scene. You may want to use this setting if using a digital video
recorder.
For example, if the dome is installed in a lobby of a busy building, you may want to program
presets that show different areas in the lobby.
Figure 12 shows a sample floor plan for the
lobby.
