The blue area indicates coverage provided by just one multidirectional camera in one of many usage scenarios.
For up to 360° overviews or great detail
Multidirectional cameras can monitor multiple directions simultaneously because the camera heads can be positioned independently. They provide up to 360° coverage in four separate streams, and you can set up the viewing angle and level of zoom for each camera head individually. So multidirectional cameras give you the flexibility to choose between overviews and images with great detail.
Multidirectional cameras are well suited for wide areas, both indoors and outdoors. They are particularly ideal for mounting on the outer corners of buildings, and at the intersections of hallways and roads.
