To start the playback of the main server archive, click the icon in the bottom right corner of the surveillance window.

Where the surveillance window isn't big enough, the icon can be hidden. In this case, enlarge the surveillance window. 

The playback control panel is displayed. It contains recordings of the main server archive.

If you selected videogate when adding cameras to the monitor (see Selecting and configuring video cameras), then after you complete the steps described above, the videogate archive opens (see Playback of videogate archive).
