Password-protection ensures that settings cannot be tampered by unauthorized persons. Zone Blanking will blank out an entire area or zone (which is set by a system operator) to eliminate any unnecessary video information from being processed, thus decreasing video traffic over a network. Up to 8 zones can be programmed to output blank video for areas not requiring video surveillance. The blank video output can be with or without labels; each label has a maximum limit of 20 characters. A Window Blanking function blocks up to 8 user-defined, 4-sided shapes from being viewed by the operator.
