is a small lens with a diameter of 1.5mm to 9.5mm used for covert surveillance.
Lenses used primarily in covert applications where the camera/lens must remain out of sight.

Is one type of standard lens available. A pinhole lens is only 1/16th of one inch in diameter, so cameras with tiny pinhole lenses can easily be hidden for covert video surveillance applications. Cameras with this type of standard lens are typically referred to as pinhole cameras. Most of the pinhole lens cameras have a 3.7mm focal length to deliver a wide field of view.
A special lens with a very small objective lens which is able to gather light through a small opening of about º”, sometimes less. These lenses are generally physically longer than a normal lens of the same focal length and are available in manual and auto-iris configuration; some are also made in a right angle form. The “F” stop of these lenses will generally be two or more “F” stops slower than a lens of comparable focal length.
A type of lens commonly used with hidden cameras.
A lens with a very small front, easily concealed, for use in covert applications.
A fixed focal length lens, for viewing through a very small aperture, used in discrete surveillance situations. The lens normally has no focusing control but offers a choice of iris functions.
This is a type of lens with a very small aperture. Normally used for covert applications, where it can easily hide behind or within another object.
Lens used for applications where the camera/lens must be hidden. Front of lens has a small opening to allow the lens to view an entire room through a small hole in the wall.
A lens with a relatively small front opening so it can be used in covert application.
