All system elements of each type are on the same layer. For example, all cameras are on the same layer. If you hide the camera layer, all cameras are hidden. From top to bottom, layers for system elements are arranged in the following order: locations, cameras, links, and geographic background. You cannot change this order.

The geographic background is always the lowest layer on a smart map. You can switch between geographic backgrounds, but you can select only one geographic background at a time.

Custom overlays are added as separate layers and are stacked in the order in which they were added to the smart map. You rearrange the order by configuring default settings for the map.
