360º Panoramic (Fisheye) – get eyes in your neck with this camera from Elotec.
This type of camera is primarily intended for indoor use in large open spaces where there is good overview. With one fisheye camera, you can cover areas that would normally need 4-6 cameras to achieve the same coverage.
From the NVR, the camera can be set up to display the original 360 image, two different panorama layouts or steerable view. This allows you to easily switch between overview images and detail views. The entire image is always saved, so you can later go back and zoom in on other sections if needed. Bundled PC software may provide other options for viewing.
