Computerized monitoring of security camera images is under development, so that a human security camera operator does not have to endlessly look at all the screens, allowing an operator to observe many more security camera security cameras. These systems do not observe people directly. Instead they track their behaviour by looking for particular types of body movement behavior, or particular types of clothing or baggage. security cameras
The theory behind this is that in public spaces people behave in predictable ways. People who are not part of the ‘crowd’, for example car thieves, do not behave in the same way. The computer can identify their movements, and alert the operator that they are acting out of the ordinary. Recently in the latter part of 2006, news reports on UK television brought to light newly developed technology that uses microphones[clarification needed] in conjunction with security camera.If a person is observed to be shouting in an aggressive manner (e.g., provoking a fight), the security camera can automatically zoom in and pinpoint the individual and alert a security camera operator. Of course this then lead to the discussion that the technology can also be used to eavesdrop and record private conversations from a reasonable distance (e.g., 100 metres or about 330 feet). Home Security Cameras
The first closed-circuit television security cameras used in public spaces were crude, conspicuous, low definition black and white systems without the ability to zoom or pan. Modern security camera security cameras use small high definition color security cameras that can not only focus to resolve minute detail, but by linking the control of the security cameras to a computer, objects can be tracked semi-automatically. The technology that enable this is often referred to as Video Content Analysis (VCA), and is currently being developed by a large number of technological companies around the world. The current technology enable the systems to recognize if a moving object is a walking person, a crawling person or a vehicle. It can also determine the color of the object. NEC claim to have a system that can identify a person’s age by evaluating a picture of him/her. Other technologies claim to be able to identify people by their biometrics.
