Mini board camera lenses are either of a "full opened" type or "pinhole" in which the opening of the lens is very small.  Pinhole cameras are what people refer to as "spy" cameras and are primarily used in the manufacture of hidden cameras. All of our hidden cameras for example utilize mini board cameras.

Focal Length

Lenses in mini board cameras have a fixed iris and in most cases they have a short focal length (the distance between the surface of the lens and it's focal point) which results in a wide angle of view. Our board cameras have a lens between 3.6 and 6mm.  What this means in practical terms, is that the area that can be surveyed is somewhat limited because they can't be zoomed in and out for close-ups or long shots.  This fixed focal length is a limitation but mini board cameras do offer a low cost solution to security needs especially in hidden camera situations.
