At least one aspect of present disclosure is directed towards a camera that includes a magnetic base and a removable main camera unit. The removable main camera unit may include an outer casing, a processor, a lens housing, a wireless communications interface, and an inner casing. The inner casing may reside within the outer casing and includes at least a metallic portion and a non-metallic portion. The non-metallic portion may form a non-metallic region that may extend from at least a first boundary of the metallic portion to a second boundary of the metallic portion through a central axis of the inner casing. The removable main camera unit may be configured to be removably coupled to the magnetic base based on a magnetic force between the magnetic base and the metallic portion of the inner casing.
