Numerous studies have tried to determine if the presence of cameras in public places reduces fear of crime in people who use the area. These studies, many of which interviewed people in the CCTV area, have examined whether consumer buying has increased in areas with new CCTV systems. The general argument is that the area will benefit from a positive economic impact when people feel safer. The findings are mixed but generally show there is some reduced level of fear of crime among people in CCTV areas, but only among people who were aware they were in an area under surveillance. Most studies exploring the perception of surveillance areas found that less than half the interviewees were aware they were in a CCTV area. Reduced fear of crime in an area may increase the number of people using the area, hence increasing natural surveillance. It may also encourage people to be more security conscious.
A third, more general mechanism by which CCTV may reduce crime is through an increase in collective efficacy. Welsh and Farrington argue that if residents see CCTV cameras being installed in their neighborhood, this will signal to them a degree of investment in and efforts to improve their local area. They argue that this might lead to greater civic pride and optimism, and, as a result, lead to an increased level of informal social control among the local people. A counter to this argument is that overt cameras may instead lead to a neighborhood being labeled as high-crime, accelerating the process of social disorganization.

Although some systems are extremely sophisticated, employing bullet-proof casing, night-vision capability, motion detection, and advanced zoom and automatic tracking capacities, many existing systems are more rudimentary. More common CCTV installations include a number of cameras connected to a control room where human operators watch a bank of television screens.
Although most CCTV schemes employ overt cameras, which are obvious (see Figure 1), it is possible to find systems in which cameras are mounted into protective shells or within frosted (polycarbonate) domes. Often termed semi-covert, these camera systems make it more difficult for people under surveillance to determine if they are being watched, as it is usually impossible to figure out in which direction the camera is facing (see Figure 2). Some cameras employ dummy lenses to conceal the surveillance target. The advantage of using a one-way transparent casing is that it provides for the possibility of retaining the overt impression of surveillance - and hence a deterrent capacity - without having to place a camera in every housing or to reveal to the public (and offenders) the exact location under surveillance.
In addition to the cameras, the cabling to feed images to the monitors, and the recording devices, a CCTV system also requires an operator to watch the monitors or review the recordings. Because of this, a full description of CCTV should not ignore the human element. Reviewing video, acting on the information, and preparing video evidence for court all create a potential need for ongoing office space and personnel costs over and above any initial capital expenditure. There may also be extra demands placed on local law enforcement as a result of increased surveillance of an area. With increased surveillance, more public order crime may come to the notice of police. With technological and personnel costs, CCTV comes at a considerable price. Though the technological costs continue to fall, the human costs do not. Therefore, you must give CCTV serious consideration before you purchase and install a system to combat a crime problem. A later section details some of the factors to consider before deploying a CCTV solution.
Fig. 2:This semi-covert CCTV camera may have a crime prevention advantage over an overt system because offenders can never be sure in which direction that camera is facing.
