About Me
When shopping for surveillance cameras you will notice that there are different camera lens types available. Each type of lens will provide a different field of view and some adjust to varying light conditions better than others. The main specifications you need to consider when choosing a lens type are focal length and iris.
The focal length of a lens is the distance between the lenses to the point at which the image is focused. This is typically measured in millimeters (mm).
There are many different focal lengths available and most security cameras will come in either varifocal or fixed lens options. Cameras with a fixed lens have a set aperture that can’t be changed.
