If you have a larger regional map that covers a geographical area, say, a street block, you can
drag one or many E-Maps into it. For example, you can place another E-Map that is used to
indicate the camera deployment inside a building that is located on the street.
To see live streams from cameras, click on the camera icons in the E-Map.
When configuring an E-Map, you can use the tilt bar on the right to tilt the E-Map image. Doing
so creates a sense of distance and depth of view.
