2. Optional Features available in VisoGuard Core/ Basic/ Extended/ Enterprise Edition


  • Mobile Client Viewing
    -iPhone Client: supports MJPEG live monitoring
    -Android Client
  • ABS

  • Smart Tripwire©
    The unique Smart Tripwire© technology prevents the duplicate and incorrect counting of objects. A Smart Tripwire© is directional and only counts objects that have been detected in the source area first and then moves across. The benefit is reducing error ratio of complex customer frequency monitoring from 20% to 5% compared to former systems despite complex shop architecture. It can be used as a Perimeter Protection in the meantime.
  • Visual Statistics©
    iCAT has the ability to collect statistics for object counts, speeds and sizes, stopped objects and objects’ stopping time. The following statistics can be visualized by intricate color overlays or normal video stream, via online monitor system and users can replay captured data.
  • Object Detection and Tracking
    For each camera, a tracking region that is either in full camera view or part view - form of a polygon or rectangle can be defined. Object detection and tracking can also be restricted by object size, speed, and X/Y size ratio.
  • Removed and Abandoned Object Counting
    iCAT could be programmed to detect removed and abandoned objects with possible constraints for stay duration and object sizes.
  • LNT
    Layout Navigation Tool (LNT) offers sophisticated navigation features for large systems. It is easy to set up hierarchical layouts as well as close integration with Thecus surveillance, therefore making it an ideal solution for larger installations.
