An Explanation Of CCTV
By Brad | April 11, 2007
The letters CCTV stand for Close Circuit Television. CCTV security is used for surveillance purposes and involves the use of one or more cameras.
All kinds of businesses, schools and organizations use CCTV for security reasons. These cameras were first designed to increase bank security. The first CCTV security systems had low-definition cameras and they were crude. They only recorded in black and white and they were not even able to zoom or pan.
The CCTV security cameras that are being made and developed now are quite sophisticated and technologically advanced. Another new feature of these cameras is the size. The new CCTV security cameras are sleek and much smaller than the older models.
You will find that the newer CCTV security cameras produce really sharp color images that are of high quality. They also have motion sensors that can track movement. These CCTV security cameras have the ability to pick out a person in a crowd and lock on them. This enables the person to be tracked.
CCTV security cameras are used to discourage and deter crime. Suspects and events can be identified and monitored which makes it easier to detect and prosecute those who commit crimes.
Traffic is now being monitored with the use of CCTV security cameras. The cameras are installed and set to take pictures of license plates. This technology is combined with radar and speeds are recorded and pictures are taken. Traffic violators are then sent tickets.
CCTV security cameras come in many sizes and shapes and can be installed almost anywhere. At some point the CCTV security system will be an entirely computerized monitoring system. At that time a CCTV operator will not be needed.
CCTV security cameras are becoming more advanced all the time.
