Real-time biometric face recognition in live video streams. Available as SDK (software developing kit) for technology integration into small and large surveillance systems. The proprietary technology provides automatic operation with multiple face detection, tracking, persons' gender determination, enrollment and identification. Can be used in security, law enforcement, visitors counting, attendance control solutions. Some applications may require to enroll the users in advance (such as list of employees or watch-list of unwanted persons or suspect criminals), whereas other just work on the general public passing by (i.e. detect if passers-by draw attention to certain ads or billboards). The SDK allows to create networked applications and systems with multiple cameras and data processing nodes on Windows and Linux platforms. Includes programming samples in Java, .NET, C, as well as all necessary components (the biometric technology, camera support, network synchronization). The trial requires constant Internet connection. See also demo video at http://youtu.be/mdhvRNYX0PI
