Surveillance adds a user interface within the 3D viewport that displays live preview thumbnails for all cameras present in a scene. Users can switch the active camera directly by clicking these thumbnails rather than selecting them from the Outliner. The interface offers two display layouts: a filmstrip mode and a tiled mode, both accessed through the Viewport View menu.

In addition to camera selection, the tool provides operators to quickly add, delete, and rename cameras directly from the thumbnail interface.
