NOTE:
180° Hemisphere
Field of View
1.Edges of a fisheye circular 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 circular view is actually larger than a 180° hemisphere.
3.Since the field of view is larger than a hemisphere, for the SF8172V, the top edge of dome cover (the round opening where the lens is installed) will appear as a white circle around an circular 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.
