S14 Camera Manual: Innovative Hemispheric Technology
INNOVATIVE HEMISPHERIC TECHNOLOGY
The Hemispheric Camera
The primary components of a hemispheric camera include a fisheye lens, a high-resolu-
tion image sensor, and image correction software that is integrated into the camera. Using
an ultra-wide angle fisheye lens, the hemispheric camera captures a 180°-hemispheric
image of the room and projects it onto a high-resolution image sensor.
When ceiling mounted, the image area of the hemispheric camera covers the entire room.
The image in the hemisphere is convex, particularly near the image borders. These image
sections are corrected for the viewer by the integrated distortion correction software,
allowing a view of the scene from the usual perspective. The virtual PTZ feature allows
you to enlarge or move image sections within the hemisphere just like PTZ camera, yet
without the need for moving parts.
Handle Several Image Sections at Once
One or more image sections can be corrected for perspective in the hemispheric view,
allowing you to monitor and record several dierent areas of a room at the same
time, something that a mechanical PTZ camera is not capable of doing.
Discreet and Low Maintenance
Hemispheric cameras are extremely discreet because they manage their
task with only one lens, which is generally focused on an entire room and
not a specific object. Hemispheric cameras are without mechanical moving
parts and require low maintenance. In addition, they are silent when panning
and focusing on a specific image area.
