Phase lock enabled

Phase lock enabled is a camera feature that allows synchronization of the
video signal to reduce the effect of picture roll on analog video switchers.

By default, the phase lock is off. As such, each camera is synchronizing its
video signal to its own internal clock crystal. This is called internal
synchronization. If you enable phase lock (select On), you are selecting what
is called line lock synchronization and the camera will synchronize its video
signal to the AC input voltage. With line lock synchronization, you also adjust
the vertical phase shift of a camera’s video signal to coordinate with other
cameras. Due to differences in cameras, environments, and cable lengths, the
phase shift will not be the same for all cameras being synchronized. Use an
oscilloscope or a GE Security vertical phase adjustment tool (KTS-56).
Contact your GE Security sales representative.

Phase adjustment

This option is available only if On is selected for Phase lock enabled.

Choices range from 0 to 127°. Default is 50°. These settings map to the 0 to
360° angle adjustment range. Use your oscilloscope or vertical phase
adjustment tool to verify settings.

Stabilization

Stabilization is a camera feature that reduces video shaking for cameras that
are located in areas prone to vibration. It works best for low frequency
vibration (3 to 10 Hz). If it is available for your camera, it creates a slight lag
and movement backward when a pan/tilt movement stops

Choices are Off and On.
