Highlighting the box under the Video Loss Interval heading allows you to set the duration of a signal loss before the

internal buzzer, notify a number of different devices, and/or move PTZ cameras to preset positions.
Highlight Use Ignoring Time and press the button to toggle between On and Off. When set to On, the DVR will
