I would like to share with you a news which I read it recently about the "Smart cameras" to tackle abandoned luggage alarms.
Mainly funded by the European Union, the two-year, 2.3 million euro ($3.11 million) project involved 10 European companies and research institutes and is known as ISCAPS (Integrated Surveillance of Crowded Areas for Public Security).
