How does a wireless camera work?

Ok so I am not talking about the camera with a screen, I am talking about a camera attached to a battery which isn't connected to anything else. Also it projects the image to a screen... So how does it work?

  • These are sometimes used in radio control planes to get aerial photos. They are also used as spy cams like nanny cams. Theyre tiny and can be easily hidden.

    Actually the camera is attached to a battery and a transmitter. The images are sent through radio frequencies to a receiver which can be connected to a computer to view and capture the images.

  • Link us to such a camera and perhaps we can figure it out for you.

    The only camera that is also a projector is this one.
