A hermetically sealed digital electronic camera that is designed to operate both on land and underwater to great depths, and method of making same. The present invention is a camera which is hermetically sealed by being totally encapsulated, preferably by being cast in plastic, with no seals, holes, joints, penetrating pins, wires or other objects. Wireless means are used for communicating information, electrical power and control signals. The invention is impervious to atmospheric contamination and absolutely incapable of leaking under water to great depths and pressures. In an alternate embodiment camera optics are not encapsulated but are immersed in water when the encapsulated digital camera is placed in water.
