The built-in record period calculator can give a rough estimation of the total recording time for the DVR with the current settings. In order to compute as accurate an estimate as possible, please enter your expectations for the hours per day you expect recording to take place due to motion events and due to other alarm conditions.

Figure 4-8 Record & Play Menu-Built-in Cal.

Motion: Enter the expected number of hours per day due to motion recording.
