How to select a proper security camera lens in 3 easy steps. Tips on CCTV Security Camera lens selection by Video-Surveillance.us
1. Should I use Manual Iris, Auto Iris or DC lens?
You can save money and use manual iris lens only when scene illumination never changes. Example: illuminated store or office.
If the light changes a lot it is recommended using auto-iris.
2. What focal length lens do I need?
Guide: smaller the focal length number => wider is field of view.
If you have security camera in the office or warehouse and you want to see as much as you can, you should go for 2.8 or 4 mm lens (makes wide, somewhat distant view)
If you want to observe limited area, like entrance you should go for 8mm or (makes narrow view and objects are closer).
