A-4 Profile Video File Server Installation
Note: Analog Composite I/O specifications are applicable when TBC is not enabled. The image quality of
any channel with TBC enabled is comparable to professional Super VHS recorder/playback quality. For
optimal image quality, and if not required, TBC should be disabled.
