Video analytics encompasses a range of software enhancements that law enforcement agencies use to improve public safety and aid investigations. Perimeter, crowd, and object detection, person tracking, and facial recognition are common features of video analytics in surveillance cameras. Video analytics’ algorithms detect changes in a video’s pixels, alerting law enforcement agencies that the software has recognized a designated object, person, sound, or behavior (eg, a person crossing a boundary). Video analytics can also be complemented by technologies such as GDT and ALPR.
