Use the arrow keys to pan/tilt the enlarged picture to allow closer inspection of any part of the selected image. Freeze : Holds the selected camera picture on either full screen or cameo. The currently selected camera image will be frozen, and "FREEZE" will be displayed on the screen. This feature allows closer inspection of any part of the selected image.

Changing the display screen mode releases the freeze mode from all cameos.

The designated camera video inputs from the record list will be recorded onto the VCR and will be available for playback.
