It is a lens with an angle of view of 180° and is also called a fish eye lens because it looks like a fish eye. Since the angle of view is wider than that of the wide-angle lens and the results of distortion in a round shape are produced during photographing, it is more often used for photographing special effects than for general use.

Even if the shutter speed is somewhat slow, excellent results can be obtained, so it can be conveniently used.

DL Filter is the deep learning classification engine. It detects only what user is interested in, people or vehicles. And it filters false alarms caused by field noise such as moving light, leaves, spiders, rain, and wildlife. Users can monitor only objects and specific events they want reducing data processing and response time, and maximizing operational efficiency by saving storage space. 

Deep Learning People Tracker tracks internal people accurately with no calibration. Additional pose estimation metadata enables new algorithms (e.g. slip, trip, fall) using existing installed cameras. 

Deep Learning Object Tracker detects people, types of vehicles and selected objects (e.g. bags). Handles dense and busy scenes. No calibration using existing installed cameras
