CCTV systems; adding value with new technology

The author examines the impact which new technologies and techniques will have upon both existing and future closed-circuit television (CCTV) systems. He considers devices ranging from video entry phones to advanced surveillance cameras and proposes ways in which value can be added by extending the range of functions which the devices can perform. Examples are presented which show how the value of CCTV systems will increase through the expansion of the basic imaging capability or through the use of CCTV within new, complex devices. Particular attention is given to the video entry phone and similar devices, where end users should expect to see products with much more flexibility and more functions. It is further noted that advances in computer technology will continue to impact upon the facilities and functions which operators have at their disposal, making through increased operator efficiency. Advanced surveillance camera systems are also considered
