Set the field of view on site

A varifocal lens lets the installer set the focal length within its range, which removes the need to know the exact field of view before the camera is mounted. Unlike a parfocal zoom, it has to be refocused after the focal length is changed, so it is adjusted once and then locked.

  • Check the mount: C-mount and CS-mount share a thread but not a flange distance, and a CS-mount lens does not focus on a C-mount camera.
  • Compare the format and megapixel rating with the sensor, and the focal length range with the widest and narrowest field you need.
  • Choose the iris for the lighting: manual for constant light, DC auto-iris where the scene brightness changes and the camera can drive it.
