The increasing use of CCTV has resulted in a rapid expansion in the types of cameras available for specific purposes; at WLS, we offer a comprehensive range.

Today, most cameras use a computer chip called a Charged Couple Device (CCD), which has largely replaced the tube. CCDs convert light into an electrical signal, which is then processed by the camera’s electronics and converted into a video signal that can either be recorded or displayed on a monitor.

Many cameras now feature Digital Signal Processors (DSPs) to increase their flexibility and enhance image quality. A DSP is essentially a computer microchip or chipset, which allows the camera to process and manipulate video images.

Premium DSPs provide backlight compensation, video motion detection, remote set-up, built-in character generator, on screen menu displays and many other functions aimed at improving surveillance efficiency. It is the combination of DSP and CCD technology which has caused the marked improvements in CCTV image quality.
