When setting up surveillance cameras, the installed lens may not necessarily be the best one for the job. The focal length of the lens helps to determine how far from and how wide of a viewing target you can have. If you know the CCD Image Sensor Size, the Distance to the Target, and the Width of the Target, you can calculate the Lens Focal Length and the Horizontal Viewing Angle. Visit our CCTV Lens Calculator page, enter your values, and press the “Calculate” button.
