118 Vision VR48 Series 4 Router User Manual
Below are 4 images depicting under-exposed, over-exposed and properly exposed/focused images.
Adjust the aperture to provide enough contrast to view all image details, then adjust the camera focus to
show the image as clearly as possible. To adjust focus, first make sure the thumbscrew for the aperture
adjustment has been tightened (this may adjust exposure slightly), then loosen the top thumbscrew on
the camera and turn the focus adjustment until the image shown on screen is crisp. Tighten the top
thumbscrew once the focus has been adjusted.
