559 CCTV can cover most blind spots. The cost of fitting CCTV systems has
fallen since the technology was first developed, and the systems are also more
reliable. The cost of fitting a system to a vehicle varies with the type of camera,
link and monitor. Companies who have fitted CCTV have found that it can reduce
the number of reversing accidents, and in this way the systems usually pay for
themselves in a few years.
560 Both black-and-white and colour systems are available. Colour systems can
provide a clearer image where there is little contrast (for example, outside on an
overcast day). However, black-and-white systems normally provide a better image
in lower light or darkness, and usually come with infrared systems, which can be
more effective than standard cameras where work happens outside during the
hours of darkness.
561 Monitors should have adjustable contrast, brightness and resolution controls to
make them useful in the different light conditions in which they are likely to be used.
It may be necessary to shield any monitor from glare by using a hood.
562 If possible, the camera for a CCTV system should be fitted in a high position
in the middle of the vehicle’s rear where one camera is being used, or in the upper
corners where two cameras are used. This will provide a better angle for the driver
to judge distance and provide a greater field of vision. It also keeps the camera
clear of a lot of the dust and spray that can make cameras less effective, as well as
usually being out of the reach of thieves or vandals.
563 However, CCTV systems do have the following limitations:
n if vehicles are leaving a darker area to a more strongly lit area (for example,
driving out of a building), the change in the level of brightness can mean that
CCTV systems do not work for a moment as they adjust;
n a dirty lens will make a camera much less effective;
n it can be difficult for drivers to judge heights and distances on CCTV monitors.
564 It is important that using CCTV systems does not lead to drivers being
complacent about safety. Operators need to know how to use the equipment
properly, and should be trained in using CCTV systems.

565 Other types of system to improve awareness for both pedestrians and drivers
are available.
566 Alarms such as radar and other devices that sense nearby obstructions are
increasingly being fitted to road-going vehicles as parking aids.
