Security Camera Lens

Security camera lens are a necessity in order for the camera to work properly. It's the security camera lens' responsibility to gather the light reflected by the objects in the field of view and focus it unto a very small sensor chip (1/4 or 1/3 square inches, usually). Working with such small surface areas to focus and entire field of view on, it's easy to see why the lenses must be high quality glass or other material.
