Figure 3-7 When GV-FER521 images are aligned, top and bottom edges will be
cropped slightly.
Note:
The circular source image of GV-FE2301 / 4301 should be centered and slightly cropped
on all four edges. If the image is not centered, please contact your sales representative and
send your device back to GeoVision for adjustment.
To determine whether your device needs adjustment, measure the length of a longer
cropped edge and the length of that entire edge. Divide the length of the cropped edge by
the length of the entire edge. The ratio for left and right edges should be less than or equal
to 5/9 and the ratio for the top and bottom edges should be less than or equal to 5/8.
