input to the digital video recorder’s alarm input terminals while the digital video recorder is online.
Motion sensor detection: This is when the motion sensor settings cause movement to be detected on the monitor screen.
Click [SAVE] to complete the settings (or changes) for the sub-menu that is displayed on the screen. The
number of alarm recordings available under the conditions that have been set will be displayed in parentheses
for reference.

displayed and pre-alarm setting cannot be carried
out.
A 60 FPS can only be selected when the NORMAL
REC AREA capacity setting is 0%.
