Image resolution is the number of rows and columns in pixels.
The 3284 x 1840 is optimal resolution setting for the cameras, however, the
resolution can be changed to decrease file size for photos of less importance
i.e., the photo of the top, or lid, of the box does not need to be as high a
resolution of a photo of a file. However, changing the resolution of a single camera
from one resolution for a particular image type to another resolution for a
different photo type is not suggested as it is not efficient. Choose a
resolution for a camera based on the photo types the camera is assigned to take
and choose the setting that is best suited for the most complex data that may
be taken with the camera. The resolution options are 3264x2448, 3264x1840
(optimal), 2592x1952, 2048x1536, 1920x1080, 1600x1200, 1280x720, 1024x768,
800x609, and 640x480.
