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, the top edge of dome cover (the round opening where the lens is revealed) may appear as a white circle around a 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.
Tips:
•The onscreen Java control can malfunction under the following situations:
