What does the term "field of view" refer to in CCTV surveillance?

The term "field of view" in CCTV surveillance specifically refers to the area that a camera can capture visually. This encompasses the extent of the observable scene that a camera can record at any given moment, which is crucial for the effective monitoring of an environment. A larger field of view allows a camera to cover more area, which can enhance surveillance efficiency by reducing the number of cameras needed to oversee a particular location.

Understanding the field of view helps in strategically positioning cameras to maximize coverage and minimize blind spots. It is determined by factors such as the lens type and focal length used in the camera setup. By knowing the field of view, security professionals can make informed decisions about camera placement and selection based on the surveillance needs of a specific environment.
