Auto Back Focus (ABF) Preference Statistics

Author: Ethan Ace, Published on Nov 26, 2011

Auto back focus has become a more common feature in the past couple of years, with many, if not most, new IP camera offerings containing this capability. Manufacturers claim that auto back focus reduces installation time and makes focusing cameras easier, especially at megapixel resolutions. How do integrators, the ones actually using (or not using) the technology really feel about it, however? As part of our Fall 2011 survey, we aimed to find out.
