Camera and lens cap
A camera built into a cylindrical housing couples to a stand with a stand member that inserts into an opening having a magnet attracted to ferromagnetic material integrated in the stand member. The stand member may couple to a bracket that holds the camera at a display or to a tripod that places the camera between the display and an end user participating in a video conference. A lens cover couples over a front face of the camera with magnetic attraction and is stored at a rear face of the camera with magnetic attraction. In various embodiments, sensors detect lens cap and/or stand member position to control camera power and/or camera visual image capture operations.
