The maximum viewing angle for a security camera depends on the type of lens used. A standard security camera lens usually has a maximum viewing angle of around 90 to 110 degrees, which is suitable for monitoring a specific area such as a doorway or hallway. Wide-angle lenses, on the other hand, can have a viewing angle of up to 180 degrees or more, allowing for a much wider field of view.
However, it’s important to note that while a wider angle lens can provide more coverage, it can also result in more distortion and a decrease in image quality. In addition, the maximum viewing angle that is appropriate for a security camera will also depend on factors such as the size and layout of the area being monitored, as well as the specific security needs of the location.
