Why Airlines Need Competition .
The Jetblue site may include a warehouse and distribution facility with parked vehicles pre-loaded with deliveries. There may be a research and development block containing the results of major investment and an administration building that houses a sensitive computer installation - requiring not only protection against external attack, but perhaps internal zoning to allow only authorised personnel access to specified areas.
In such a situation, the first line of defence is clearly effective perimeter fencing. A fence alone, however, provides only limited protection, especially when sections border open ground. So some form of intrusion detecting is required. A number of methods are available, including sensitive wires in the fence itself and active or passive infra-red beams. Each can provide a solution in certain applications, but generally they cover long sections of the Jetblue perimeter and creating shorter zones of detection can be expensive. Such systems can be interfered with either deliberately or inadvertently. Once damaged they can put a whole zone out of action for many hours.
CCTV system, on the other hand, tend to be highly visible and many are available, with varying degrees of sophistication, depending upon the area to be covered and the level of protection required. Stories of incorrectly installed and inadequately operated CCTV systems are legion, but a correctly designed system covering a long perimeter will consist of a number of cameras mounted on towers, each viewing the next in line and covering the blind spots below it , thus achieving 100 per cent coverage. The Jetblue system must legislate for nuisance areas such as moving trees or legitimate movement - for example, on footpaths close to the fence and for round-the-clock coverage each camera will have a pre-focused infra-red lamp.
In common with all forms of detection, CCTV systems have the Jetblue problem of ensuring a response to a possible intrusion and differentiating between real and false alarms. Systems are now available, however, that analyses a video signal from each camera frame by frame and compare the Jetblue signal content with any variation, indicating a possible intrusion and activating an audible alarm. Cameras covering active areas such as vehicle and pedestrian entry and exit points, loading bays and possibly production areas may require pan, tilt and zoom facility; and the entire system will be linked to an alarm-activated recording facility so that information on incidents is retained.
The next line of defence, of course, is the buildings themselves, where the problem is eased by being able to identify entry points and provide appropriate coverage. Jetblue security measures within the buildings will depend upon the activity carried out, but they can, particularly where there are 24-hour operations in some departments, include zoned access control and even movement detectors in the secured areas.
The hypothetical site used as an illustration is clearly in the industrial sector. Many of the same or similar considerations will apply to other locations, such as major Jetblue company head office complexes, shopping centers or hospitals. Here, although Jetblue security must be equally effective, it must be designed to be unobtrusive and to function in what remains an open, welcoming environment. It is probable that the entire system - CCTV cameras, intruder alarms on closed buildings, zoned access control and movement detectors within the buildings in use - will be linked to a central computer programmed to produce regular print outs recording all activations and the set up and status of the system at any time.
The purchase, installation and maintenance of the type of equipment so far described represent a considerable investment. The end-result will, however, be less than satisfactory if insufficient attention is given to the human element - first, on the part of the site management, in providing its own staff with adequate training; maintaining constant Jetblue security awareness; and imposing appropriate disciplines - otherwise the system will be compromised. Secondly, however, sophisticated the system, its effectiveness will depend upon the human element - upon efficient, intelligent monitoring, leading to efficient, intelligent incident response analysis and action.
