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.Â
- 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.
