At a time when there is high pressure and scrutiny around security, innovative new technologies are helping to track and predict crime. Artificial intelligence (AI) is key in this new way of fighting crime, providing analysis that can give real support to law enforcement services as they make difficult decisions about how best to use their resources. CCTV cameras have been in use in Europe since the Second World War. However, they have sometimes come under scrutiny about their effectiveness when it comes to tackling crime, as they tend to only provide retrospective support for law enforcement (such as placing a suspect at the scene of the crime in their trial). With new cameras able to send and receive data via a computer network and the Internet (IPTV), as well as the huge amount of data collected every second using traditional CCTV, AI can collate this data extremely quickly ready for analysis.
