SentiVeillance Server

Face identification and movement tracking for video management systems (VMS)

SentiVeillance Server is a ready-to-use biometric face identification and movement tracking software designed for easy integration into operating video management systems (VMS). The software analyzes live video streams, which are served by a VMS from surveillance cameras.

The list of possible uses includes law enforcement, security, attendance control, visitor counting and other commercial applications.

Designed for installation on server hardware which is running under Linux.

Technical details

SentiVeillance Server software is based on SentiVeillance 6.0 SDK technology which provides real-time facial recognition and movement tracking for video surveillance systems. SentiVeillance Server has certain specifications and requirements for achieving best performance:

  • Face size in a frame is important for reliable face tracking and biometric identification. 4 % of the frame's larger side (at least 32 pixels) is the minimal recommended distance between eyes for a face on video stream. The performance depend on actual size of a face in a video stream, not on the size of the whole frame.
  • Face posture can have certain difference from frontal position. SentiVeillance Server assures accurate face detection and tracking when the face posture meets these constraints:
    • head roll (tilt) – ±15 degrees from frontal position;
    • head pitch (nod) – ±25 degrees from frontal position (several face views should be enrolled);
    • head yaw (bobble) – ±45 degrees from frontal position (several face views should be enrolled).
  • Face enrollment can be done either from live video or still image.
    • Image quality during enrollment is important, as it influences the quality of the face template.
    • Several images during enrollment are recommended for better facial template quality which results in improvement of recognition accuracy and reliability.
    • Additional enrollments may be needed when facial hair style changes, especially when beard or mustache is grown or shaved off.
  • Face record size in the watch list is 7 kilobytes. A person can have multiple face records stored.
  • The matching against a watch list is done in less than 0.5 seconds when the watch list has 20,000 face records.

The browser-based administration interface for SentiVeillance Server software allows to manage the system via remote connection. Administrators can overview the connected video management systems status, as well as perform these tasks:

  • VMS connection management.
  • Watch list management, including new persons enrollment.
  • Biometric engine configuration.
