Abstract
Generally discussed herein are techniques, software, apparatuses, and systems configured for detecting an anomaly in a camera. In one or more embodiments a method can include: (1) determining a first property of a reference image, (2) determining a second property of a second image captured after the first image, wherein the second property is the same property as the first property, (3) comparing the first property to the second property, (4) determining a lens condition, a protective cover condition, an image sensor condition, a focus, or a field of view of the camera has changed since the first time in response to determining the first property is substantially different from the second property, or (5) sending an alert indicating that the lens condition, the protective cover condition, the image sensor condition, the focus, or the field of view of the camera has changed.
