Varifocal vs. Fixed Lens Integrator Preference

Author: Ethan Ace, Published on Dec 26, 2011

When selecting lenses for surveillance cameras, there are two fundamental options: varifocal and fixed focal length. Varifocal lenses allow the field of view to be adjusted within a range (e.g. 3-8mm, 9-20mm, etc.) after the camera is installed, without changing lenses. Fixed focal length lenses are just that, offering only one focal length. As part of our Fall 2011 integrator survey, we aimed to find out which of these two options integrators were most often installing.

We asked the following question of 84 integrators:
