7.2.2 Recording
Recording can be performed in different modes such as continuous, on schedule or on event trigger according to
their needs. On-schedule or event-triggered recording is highly needed because the storage requirements will be
reduced; so is the bandwidth.
In an IP surveillance system, the frame rate is changeable. Therefore, users can set the system to use a lower
frame rate during live monitoring for low bandwidth usage while shifting to a full frame rate during event-triggered
recording to ensure good image quality (Figure 7.7).

7.2.3 Playback
Recorded video images can be viewed in multiple split windows and by several users at the same time. The
recorded database can also be searched in a more efficient way such as by date, time, region or event.
