Why the French spot terrorists better than Americans

     Since 9/11, there have been many civil rights-related questions raised about video surveillance. What has been discussed less frequently is the actual quality of the video displayed and recorded; a simple question might be posed: "Why do even...


Overall intelligence

     Another key advantage of digital surveillance cameras is overall intelligence. Because of extensive computing power and the ability to program cameras to do a number of tasks, these cameras are really systems, as opposed to analog devices, which merely record images. Intelligent digital surveillance cameras can be programmed to recognize event triggers and generate alerts, which can then be sent over the Internet to a phone, PDA or computer. In addition, because of the Internet factor, one can remotely monitor a local or global area from a central control or alarm monitoring facility, as well as from a mobile phone or other handheld device.

     Beyond being able to see more clearly, digital cameras see and record more overall. One high-resolution digital camera can easily produce detailed images of an entire room, compared to the two or three analog cameras necessary to do the same job. One camera versus two or three for the same room is definitely more cost effective.

     Event-controlled image rate also saves money by minimizing storage costs. Instead of running a camera 24/7 and viewing hours of film to locate the necessary sequence, some newer camera systems use event-driven, automatically adjusted, digital recording frame rate based on event or sensor action. These systems only capture data when action occurs, thereby reducing the amount of captured footage and simplifying the time it takes to locate video data related to a specific incident.

     Some intelligent digital cameras are also optimized to work in worst-case scenarios. If the network breaks down and there's no connection or power, these cameras can be configured to switch to a wireless mode and UPS (power backup) to send images to another emergency processing center. When one considers that the alleged New Jersey terrorists wanted to cut power to Fort Dix so that soldiers would come out into the open as targets, the importance of a good backup system cannot be overestimated.

Looking ahead

     U.S. officials can learn from the French. It is better to be prepared before an incident occurs than react to it after the fact. More than six years after 9/11, America remains vulnerable to terrorists on many fronts — ports, nuclear facilities, public transportation and more. Yet the country has not sufficiently modernized its video surveillance systems to meet current security needs.

     The CCTV industry is part of the roadblock in this case. Its influence is being felt far and wide as companies attempt to forestall the inevitable: adoption of digital video surveillance as the industry standard. However, such efforts likely will not be successful. There is simply too little to gain and too much to lose to continue to uphold technology from another era that doesn't provide adequate security, and in the final analysis is actually more costly than digital cameras in terms of maintenance and limited functionality. The ability to do much more with less is one of the hallmarks of the Digital Age, and this is certainly true when it comes to surveillance cameras. It just doesn't make sense to simply increase the number of surveillance cameras if, at the same time, the quality of the systems is not improved to produce useful images.

     The El Segundo, California-based market research firm, iSuppli Corporation, projects that it is not a question of if, but when, IP cameras will displace CCTV. The firm estimates U.S. revenue for IP cameras will be close to $6 billion by 2011, with CCTV revenues dropping steeply downward toward obsolescence.

     In the meantime, law enforcement officials and U.S. civilians can begin to encourage legislators to enact a law similar to the new law in France: one that holds video surveillance in public places to a higher technological standard. As we near the seven-year anniversary of 9/11, it's the least we deserve.
