SmartVision combines several analytics layers. Motion detection is the basic level. It filters out empty scenes and triggers recording only when something changes. On top of that comes object detection, face recognition, license plate recognition, smoke and fire detection, and neural audio analysis. Together they create a system that can both see and hear what is happening.
The role of facial recognition remains one of the most visible parts of video analytics. The process starts with face detection. The system scans video frames and finds areas that look like human faces. After detection, the software extracts unique facial features and creates a digital template called a faceprint. This template is compared with a database to identify people in real time or during archive search. In practice this is used for access control, visitor tracking, attendance monitoring, and security alerts when a known or unknown person appears.
License plate recognition works in a similar way. SmartVision detects vehicles in the frame, isolates the plate, and converts it into text. This allows automatic gate control, parking monitoring, and vehicle search in the archive. Instead of manually reviewing video, users can simply search by plate number and jump directly to the moment the car appeared.
However, video analytics in SmartVision goes beyond image analysis. One of the most important recent additions is sound detection. Traditional surveillance systems are effectively silent. They react only to movement. This creates blind spots. Many critical events happen without visible motion. A baby crying, a person shouting for help, a gunshot, breaking glass, or a distress word can occur outside the camera view or in poor lighting. Without audio analysis these events remain invisible to the system.
