Used primarily in the beginning as a traffic-monitoring device nike air max 90 růžové , remote security cameras are becoming the weapon of choice in the war against terrorism and crime around the world. A trained technician can sit in a control booth and monitor cameras placed in many locations around the city and using his remote equipment, he can pan and tilt, turning the cameras at will to view an even larger area than would be possible with stationary security cameras.
The latest spy programs on TV use these cameras to monitor good guys and bad guys having clandestine meetings in downtown areas. They can pan and follow two people who are walking and talking and when they've reached the outermost edges of the camera's field of vision, they merely switch to the next camera and pan and tilt all over again.

In the aftermath of a terrorist attack, like the recent events in the London subway system, those cameras could have noticed the packages containing the bombs used to blow up those trains.

Furthermore nike air max 90 cierne , these remote security cameras are being used more and more to watch the habits of people in crowded areas, subway stations, airports and others to try to stop a terrorist attack before it happens. If someone enters an airport with a backpack, a trained technician sitting in a control booth far from the actual place he's watching could track this person's movements throughout the entire airport; so if he leaves his bag or does something else suspicious nike air max 90 sk , it would be noticed immediately and dealt with quickly. All without the person being watched ever knowing he's being watched.
