As primary commerce hubs, ports are obvious targets for crime and terrorism. One of the primary tools that port security directors have relied on for security is video surveillance. The approach of recording video, reviewing the tape for improprieties apprehending the offender has worked somewhat for run-of-the-mill criminal activity. With today's threat from terrorism, however, this approach is no longer acceptable. The latest trend in port security focuses on implementing an enterprise approach in which all of port's sensor technologies including video, chemical, fire and others are linked together through information technology into a single, smart command center.
