After 9/11 law enforcers and security officers are turning to wireless surveillance cameras and communication system to secure and protect transport terminals, airports, seaports, subway trains, property, government offices, business establishments and even schools in many parts of the world in the fight against terrorism and lawlessness.
Security has become top priority in education, transportation, health care, governments, banking and finance, manufacturing/industrial and retail, forcing a reevaluation of previous assumptions about evenly and making investments in new technologies a necessity.
The increase use of surveillance cameras and videos has become the foundation and one effective way to prevent it is through the use of state of the art equipment and technology, from recording and aiding in the apprehensions of criminals and at the same time used as a deterrent.
In the aftermath of the London subway bombing in 2005 resulting in 52 deaths and dozens of others wounded, the British system of surveillance cameras has proven its capability both as an anti crime and forensic tool when it was able to record and identify the suicide bombers that led to their apprehensions by Scotland Yard within days after the commission of crime.
It is no doubt, reassured the jittery British public at that critical moment. The wireless surveillance and communication system are operated in a communication center away where the cameras have been installed. They can be made to pan, zoom and tilt.
Its sophisticated imaging technology allows cameras to alert law enforcers to unattended packages, zoom in objects hundreds of feet away and to pan audiences to enable police and security officers to see if there is imminent danger to the public or to any VIP and his entourage.They can also alert law enforcers to suspicious vehicles that repeatedly circle the same block.
In the US, the speed with which the London bombing was solved has prompted calls from the politicians and law enforcers to emulate the British system. New York is the first city to set up live networks tied to a central surveillance center. Other American cities that will follow suit are Chicago and Baltimore.
By 2010, as many 3,000 cameras shall have been installed, still a pittance compared to 200,000 cameras in London which develop the surveillance system since 1970 in response to the deadly attacks by the Irish Republican Army.
In New York, the government owned one third of the 3,000 cameras to be installed and two thirds by private security working with business establishments.
