Abstract

Recent years have seen significant investment and increasingly effective use of Video Analytics (VA) systems to detect intrusion or attacks in sterile areas. Currently there are a number of manufacturers who have achieved the Imagery Library for Intelligent Detection System (i-LIDS) primary detection classification performance standard for the sterile zone detection scenario. These manufacturers have demonstrated the performance of their systems under evaluation conditions using an uncompressed evaluation video. In this paper we consider the effect on the detection rate of an i-LIDS primary approved sterile zone system using compressed sterile zone scenario video clips as the input. The preliminary test results demonstrate a change time of detection rate with compression as the time to alarm increased with greater compression. Initial experiments suggest that the detection performance does not linearly degrade as a function of compression ratio. These experiments form a starting point for a wider set of planned trials that the Home Office will carry out over the next 12 months.
