DOCUMENT INFO
Description: Hemispheric camera technology is not to be confused with the generic panoramic (wide- angle) video technology offered by some IP camera manufacturers, which often deliver disappointing image quality and are costly to support at the back end. Based on the centralized system topology, these IP cameras are server-centric, meaning the entire camera system relies on a central DVR/NVR to handle the image analysis, video processing and storage management.
