CCTV installations have played a key part of the defenses against terrorism since the 1970s. Cameras have also been installed on public transport in the
hope of deterring crime. A more open question is whether most CCTV is cost effective. While low quality domestic kits are cheap the professional installation and maintenance of high definition CCTV is expensive. Gill and Spriggs did a Cost effectiveness analysis CEA of CCTV in crime prevention that showed little monetary saving with the installation of CCTV as most of the crimes prevented resulted in little monetary loss. Critics however noted that benefits of non monetary value cannot be captured in a traditional Cost Effectiveness Analysis and were omitted from their study. A 2008 Report by UK Police Chiefs concluded that only 3% of crimes were solved by CCTV. In London, a Metropolitan Police report showed that in 2008 only one crime was solved per 1000 cameras. In some cases CCTV cameras have become a target of attacks themselves. In the United States, Britain, Australia and New Zealand, CCTV is widely used in schools due to its success in preventing bullying, vandalism, monitoring visitors and maintaining a record of evidence in the event of a crime. There are some restrictions on installation, with cameras not being installed in an area where there is a "reasonable expectation of privacy", such as bathrooms, gym locker areas and private offices unless consent by the office occupant is given.

good reasons to invest in a security camera system for the home. One of the most profound is probably the fact that a good system will provide you with tremendous peace of mind that criminals might think twice before making an attempt on your home. Some of the most damaging crimes executed by professionals
require a certain degree of scouted information ahead of time.
