Vivotek FE8172 User Manual page 33

NOTE:
1. Edges of a fisheye oval view will be slightly cropped because the fisheye lens FOV is larger
than the sensor can take.
2. The camera lens' angle of view is larger than 180°. Therefore, the camera's oval view is
actually larger than a 180° hemisphere.
3. Since the field of view is larger than a hemisphere, for the FE8172V, the top edge of dome
cover (the round opening where the lens is installed) will appear as a white circle around an
oval view.
4. When using the dewarped modes, e.g., the Regional and Panoramic views, the firmware will
not capture the far edges of the FOV which extends beyond the 180° hemisphere.
