Personal Privacy Shutter

Hello, I am looking for a mechanical shutter to mount on the camera for privacy when the camera is not in use. Does anyone know of someone that manufactures one? It would be moved at least daily so a piece of cardboard or what ever is not a good solution.

Iā€™m not aware of any, but I use a smart plug on the cameras I only want turned on at certain times. The smart plug I use has a programmable schedule.
