sensitivity values.
Highlighting the box under the Activation Time heading allows you to set the duration before the DVR will report a

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