Video analytics is a technology that processes a digital video signal using a special algorithm to perform a security-related function. There are three common types of video analytics:
Fixed algorithm analytics
Artificial intelligence learning algorithms
Facial recognition systems
How Video Analytics Work
For the majority of video analytic systems, they work in a series of processing steps. As a fundamental first step, the content needs to dissect what is happening in the video, frame by frame. Video analytic systems work on these two key concepts:
Motion Detection: By examining each pixel in the frame, the video analytics software is able to pick up even the slightest movement.
Pattern Recognition: Objects are distinguished within a frame. Specific objects/patterns can be programmed for recognition and will be recognised within the frame.
