The challenge is to provide an extremely high level of protection, while retaining the support of the travelling public and allowing airlines to keep to their schedules. Biometrics has recently become the hot topic with airport security. Complex systems check fingerprints, retinal scans, and facial patterns to determine if a traveller is who they say they are - or if they match a list of people the government has determined might be potential terrorists. Aviation laws have tightened in requiring scrupulous access control over secure areas. Certain areas must be locked down, monitored and status reported to the system. Ability to search digital video data associated with events is crucial. Response times to priorities must be immediate, with decisions affecting passenger and cargo safety, thus the requirement for detailed, real time visual and factual information is evident. Access systems that are duly applied to this dynamic industry have the ability to integrate with flight display systems. In flight, CCTV systems monitor activity in the cockpit and passenger cabin, and provide cargo hold surveillance. |
