RIVA stands for ‘Realtime intelligent Video Analytics’, an intelligent 3D-video analytic system from the German company ViDiCore, which is already integrated in all RIVA cameras and encoders as standard.
The basic version VCA Presence continually tracks moving and stationary objects and persons in predefined detection zones and generates real-time alerts. Up to 40 zones per image can be set. Camera tampering (covering, bagging, defocusing) can be detected. A self-learning algorithm ignores repetitive movements like moving trees or rippling water. Thus, false alarms are reduced to a minimum, it is claimed. These VCA packages can be purchased additionally:
VCA Count is a counting module with a bi-directional line-crossing filter for people-counting in busy doorways and entrances. Shoulder widths can be entered to improve the counting accuracy. It is also the makers say suitable for counting vehicles. Thus, this module is used for example to count customers in retail stores or to monitor traffic flows.
The VCA Detect module was developed for perimeter protection. It includes the object classification as well as direction-, speed- and dwell filters. That means objects (persons, vehicles, animals) are differentiated and their heights as well as their speeds are detected. The analytics recognises in which direction an object moves or how long it dwells at a specific point. If a more detailed perimeter protection is needed, the VCA Surveillance package is based on VCA Detect and includes a filter for access control. VCA Advanced offers a filter for people and vehicle counting.
While the above mentioned analytic packages are suitable for all Full HD and D1 cameras, VCA Track is a package for RIVA PTZ dome cameras and one channel encoders. Besides the VCA Surveillance functions, this module includes an automatic object tracker. Visit www.rivatech.de.
