Intelligent Video System (IVS):

Intelligent Video Surveillance involves the processing of recorded video. IVS is designed to detect events with predefined criteria. Appropriate configuration of the function on the DVR level allows continuous analysis of the recorded image and enables very quick detection of unwanted events. The functions include: virtual line crossing detection, zone intrusion detection, object disappearance/appearance detection, face detection, camera alignment change and lens painting detection, and sound detection.

Perimeter protection:

Using a deep learning algorithm, Dahua Perimeter Protection technology can accurately recognize humans and vehicles. In restricted areas (such as pedestrian and vehicle zone), the number of false alarms of intelligent detection depending on the type of target (e.g. triage detection, intrusion detection, fast moving detection, parking detection, location detection and collection detection) is greatly reduced.

SMD Plus:

SMD Plus, referred to as Smart Motion Detection Plus is an upgraded version of SMD that significantly improves alarm accuracy by using a deep learning algorithm. It analyses person silhouettes and vehicle shapes based on motion detection and only sends alarms when a person and vehicle enter the detection zone. The function is activated by selecting SMD or IVS&SMD in AI mode.
