CCTV video analytics is a branch of Al that specializes in using computer vision techniques to analyze video footage and identify objects and events that have occurred. This technology is often used by law enforcement agencies to detect and track criminals who operate in crowded or dangerous areas. It can also be used to identify suspicious behavior in large crowds of people. For example, CCTV cameras can be used to identify people in a crowd who have run into a burning building. They can also be used to monitor the movements of vehicles that enter a restricted area.
Video analytics is a technology that uses a unique algorithm to process a digital video signal in order to carry out a security-related task.
