CCTV Surveillance Camera Lenses

 

NOTE: You can not use a C-mount camera with a CS-mount lens - the lens won't fit.

    CCTV Lens Definitions


  • Vari-Focal Lenses: Manually adjust focal length. Allows wide or narrow view

  • Manual Iris Lenses: Use where the light conditions remain constant

  • Auto Iris Lenses: Use where light conditions vary

  • CS-Mount Lens: Will only fit CS-mount cameras

  • Board Lens: This lens is designed for board cameras only

 

Refer to the following chart for determining field of view when considering any C-mount or CS-mount lens. The 3.6mm lens is highlighted for comparison since that is the most common fixed focus lens.
