Idea of Device Manager Icon
It's an icon of a Device Manager. There is a smartphone with the camera facing forwards. In front of the camera is one of those metal toolboxes with the metal latches on the side.
This Device Manager icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,200 icons, all in the same style and quality.
