When multiple cameras are connected to the same switching device, vertical roll can occur on the monitor. AC line lock eliminates vertical roll by
locking the frame rate to the power supply frequency. Each camera output is synchronized to the power supply frequency.
Internal line sync disables line lock and synchronizes cameras internally.
Set SW1-2 to OFF to use the AC line lock. Set it to ON to use the internal line sync. The default setting is OFF.

SW1-3 is controlled through the on-screen menu. Refer to Scan Menu in Figure 8 on page 13, and SCAN under the heading CAMERA on page 15
for more information.
