From passive to active video surveillance : Video Analytics Packages
RIVA stands for “Realtime Intelligent Video Analytics” an intelligent 3D-video analytic system which is already integrated in all RIVA cameras and encoders as a standard feature at no extra costs. 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 different zones per image can be set. Furthermore, camera tampering (covering, bagging, defocusing) is detected. A self-learning algorithm ignores repetitive movements like moving trees or rippling water. Thus, false alarms are reduced to an absolute minimum. The following VCA packages can be purchased additionally.
VCA Count is a special counting module with a bi-directional line-crossing filter suitable for people counting in busy doorways and entrances. As a special feature shoulder widths can be entered to improve the counting accuracy. Furthermore it is also ideally 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 specially 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 recognizes 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 the perfect solution. It is based on VCA Detect and includes additionally a filter for access control. Moreover it is optimized for outdoor use. VCA Advanced offers additionally the 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 special package for all RIVA PTZ dome cameras and one channel encoders. Additional to the VCA Surveillance functions, this module includes an automatic object tracker.
