Case study of a perimeter security deployment with multiple camera tracking video analytics
The article describes a case study of a perimeter security deployment with multiply camera tracking video analytics. We have applied (1) the methodology for an automated designing and evaluation of the effectiveness of security systems, developed by the company “Amulet”, weaherproof cameras family "MBK" of "ByteErg”, video analytical device «MagicBox» and video server “VideoServer iX” of the company “Aggregator”; outdoor video analytics company Synesis; a video management platform "Intellect" of the company «iTV». A quantity evaluation of the accuracy performance of the surveillance system has been done, as well as an estimation of the image quality and frames from the video archive have been shown. The parameters of the video analytics settings (calibration) have been described. A multiple camera tracking system has been implemented.
