If cameras are out of phase with each other, they may produce what appears to be vertical roll
when switching between cameras.
There are two settings for line synchronization:
On - Adjust the synchronization of the power line voltage so that it is in phase with other
cameras.
Off - The dome synchronizes to an internal clock.
To change the line synchronization settings:
1. Program preset 95 (28). The main menu appears.
2. Position the cursor (>) beside Line Sync.
3. Press the Iris Open button. The Line Sync menu appears.
4. Position the cursor (>) beside one of the choices. Press the Iris Open button.
LINE SYNC - The cursor moves to one of two choices: ON or OFF. Move the joystick up or
down to toggle between them. Press the Iris Open button to select the choice. If you changed to
OFF, the camera may reset itself as it adjusts to the new synchronization. If the camera resets,
it will only affect the line synchronization. It will not change any other camera parameters, such
as auto focus or auto iris. Press the Iris Close button if you do not want to change the setting.
NOTE:
On power-up, the
auto scan tilt angle will be
whatever angle the camera
was at when the right scan
limit was set.
