Tips on CCTV Security Camera Lens selection by Promax Security

How to select a proper security camera lens in 3 easy steps and save money doing it?

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 securit 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).
  • Give us a call and we can help you determine what security camera lens will best suit your location.
  • Use varifocal lenses to get flexibility for choosing best field of view.
