IQeye Camera Forensic Field of View Calculator

Determine the approximate field-of-view (degrees) needed to achieve desired detail,
depending on where the camera is mounted.

If you know where the camera will be mounted, this design tool will help you determine the approximate field of view (degrees) you need in order to achieve the desired detail with a specific resolution IQeye camera. This can be very useful for selecting the right lens for your application.
