What Is Video Analytics?

Video analytics is software that analyses video automatically to detect, classify and track people, vehicles and events, so operators do not have to watch every screen. Modern systems use AI models and often run at the edge, on a computer beside the cameras, to react in real time and avoid sending every stream to the cloud.

The Short Answer

Older video analytics relied on simple rules such as motion in a zone, which raised false alarms from shadows and weather. AI-based analytics recognize what is actually in the frame, so alerts are more reliable and the system can follow a specific target, count objects or read number plates.

  • //
    Intrusion detection Alerts when a person or vehicle enters a restricted area.
  • //
    Object tracking Follows a target across frames and cameras.
  • //
    ALPR Reads number plates for access control and enforcement.
  • //
    Counting and flow Measures footfall, traffic and queues.

Why It Matters

Running analytics at the edge cuts latency and bandwidth. Our object tracking case study tracks targets on a rugged Jetson computer, and our object tracking FAQ explains the technique. See our work in surveillance.
