NOTE:
1. Edges of a fisheye circular view will be slightly cropped because the fisheye lens FOV is
actually 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:
1. The onscreen Java control can malfunction under the following situations: A PC connects to
different cameras that are using the same IP address (or the same camera running different
firmware versions). Removing your browser cookies will solve this problem.
2. If you encounter problems with displaying the configuration menus or UI items, try disable
the Compatibility View on IE8 or IE9.
You may also press the F12 key to open the developer tools utility, and then change the
Browser Mode to the genuine IE8 or IE9 mode.
