Siqura enlarged the view of the PTZ dome cameras. When tilting to horizontal position or even higher, the camera no longer sees the inner wall of it's own housing. The upper part of the image is no longer black.
Not only the sphere is transparent, also the cilinder part (before white) is transparent now.
Remark: Use fixed or manual focus when viewing through the cilinder part of the transparent dome.
