6 The Sony Guide to CCTV . Issue 3 What is Closed Circuit Television? Closed Circuit Television (CCTV) is a television system which operates on a ‘closed loop’ basis. Unlike broadcast television, which is available to anyone with a suitable receiver, CCTV pictures are only available to those directl...

When and where should it be used? Security and surveillance are the most accepted applications for CCTV systems. With the use of CCTV, managers and supervisors can control risks and minimise costs efficiently and with the minimum of disruption. Security applications As well as acting as an effective...

Light The human eye and the camera lens operate on completely different lines. Although the human eye adjusts automatically to various light conditions, the camera is inherently less flexible. In a CCTV system, lighting has to be ‘designed in’ from the beginning if the best results are to be obtaine...

Backlight Compensation It is also important to consider whether there are bright spots in the picture such as car headlights which can make identification of the vehicle registration or model impossible. This can also be a major problem where it is necessary to identify persons who are moving from b...

Choosing a Camera The camera is the ‘eye’ of a CCTV system and at its core lies CCD (charge coupled device) technology. The CCD is comprised of about 500,000 light sensitive cells called picture elements (pixels) which convert the light falling onto its surface into an electrical signal. The perform...

Sensitivity Colour cameras generally perform less well in low light than monochrome cameras, all other things being equal. Sensitivity is usually measured by reference to the lux level at which a camera can produce an image (see page 9). The lux valuation, although usually referred to as a metric un...

Camera Resolution The higher the resolution the sharper the picture. The best resolution available at present for CCD cameras is approaching 750 horizontal lines (TV lines) (3-CCD, DXC-950P) and 500 vertical lines. Resolution is not necessarily the key decision point. Low resolution CCTV, which is u...

Selecting the Correct Lens The quality of the lens is vital in determining the quality of the final image. The basic optical characteristics of a lens are the focal length (in zoom lenses the focal length range) or angle of coverage, and the aperture range. We’ll look at these two characteristics to...

Aperture range The aperture is the clear opening in the centre of the lens that allows light to pass to the pick-up device. The aperture size is described in relation to the focal length (F). Thus the aperture is specified by an F number. If the lens has a focal length of 50mm and if the diameter of...

Which Monitor? A control room operator may be required to view images on a bank of monitors for prolonged periods. As the effectiveness of the surveillance system is crucially dependent upon the degree to which the operator can remain alert and avoid fatigue, correct monitor selection is vital. The ...

Transmission of Video Signals A CCTV signal contains a wide range of frequencies from around 30 hertz to around 10 Megahertz. As a result special circuits are required to cope with the wide band-width if signal quality is to be maintained during transmission. Because signals from CCTV cameras often ...

Twisted Pair An alternative to the use of coaxial cable is the ‘twisted pair cable’. A twisted pair cable is known as a ‘balanced’ cable and can be similar to telephone wires. Most of the same considerations apply to twisted pair as apply to the coaxial but there are some expectations. The twisted p...

Video Switching and Multiplexing If a system consists of a single camera and monitor, then a switching device will not be required. It would not, of course, be practical or desirable in a multi-camera system to have a monitor for every camera. In these cases, a switcher will enable the video signal ...

Multiplexers Multiplexers are a more functionally useful way of handling a multi-camera system. Like a switcher, several cameras (usually up to 16) can be connected to the multiplexer. A single field or frame from each camera is successively output via the multiplexer onto a video recording. Playbac...

CCTV Systems Control While the majority of cameras are installed in a fixed position, in order for the operator to be able to follow an incident it can be very useful to have the facility to pan, tilt and zoom the camera. This is achieved by the use of a mechanical pan and tilt head on which the cam...

Recording While a proportion of surveillance systems are continuously monitored, these are in the minority. The majority of systems are not actively monitored and, even when they are, in most cases, the images are still recorded. The underlying principle to be considered in relation to the recording...
