CCTV and imaging technology
Video based detection systems
Video based detection systems (VBDS), sometimes known as Video analytics (VA) systems use video feeds, typically from CCTV systems to provide automated surveillance through real-time video analysis and event detection.
VBDS can be configured to detect defined alarm events such as the presence of a parked vehicle in a defined zone, to track a target within a scenr, detect suspicious behaviour or categorise objects within a scene to enhance metadate searches.
The government is commited to promoting the development of VBDS to help in policing and counter-terrorist operations.
The performance of VBDS can vary with the changing environmental conditions, particularly when used for outdoor applications. These variations often cause systems to generate a hight number of false alarms, reducing their effectiveness.
Image library for intelligent detection systems (i-LIDS)
HOSDB in partnership with Centre for the Protection of National Infrastructure have developed an imagery library to help develop and evaluate the performance of VA systems - i-LIDS is the governments benchmark for VA systems. There are currently five scenarios within i-LIDS.
Video Analytics
HOSDB monitors new developments in video analytics (VA) to ensure that they are assessed by government and used where they may be beneficial.
HOSDB is also involved in the EU supported automatic detection of abnormal behaviour and threats in crowded spaces (ADABTS) project. It aims to help protect people, property and infrastructure against threats of terrorism, crime and riots, by the automatic detection of abnormal, potentially threatening, human behaviour of crowds or individuals in crowds - while respecting privacy and civil liberties.
