Spy cameras can take many shapes and forms. One kind of camera is the Microdot Camera. It stores information on a tiny film called Microdot film. Spies hide the film in a special coin. If the coin is opened the wrong way the film will be destroyed.
The Minox camera is a very famous spy camera. It can fit in the palm of your hand but it is not hidden in objects.
One hundred miles above the earth a satellite spy camera can take pictures of objects smaller than a yardstick. It is a modern camera and is used for spying today more than the other cameras.
