Surveillance is considered to be the process through which activities and behavior is monitored. This is mainly done to influence, manage and protect people. Surveillance may be carried out from a close or a far distance, depending on the equipmet that is being used to carry out the activity. An example of an electronic equipment that may be used in surveillance may include the closed circuit television. Some non-technological methods of surveillance may also be used. These methods may include the agents of human intelligence as well as the postal interception. France is considered to be the country that came up with the word surveillance, which was particularly meant to mean watching over someone. The services that are offered by the surveillance cameras are mainly employed by the government agents especially when they are trying to gather some imformation on a particular case. In addition to some of the benefits of surveillance, their services are also used in the protection of important government officials from harm and crimes that may be destructive. Criminal organizations also use the surveillance method to plan the way through which crimes may be committed. The plans may involve crimes of kidnap and major robberies. The surveillance services are also used in banks and the shopping centers to monitor the activities that are taking place and to prevent theft. After the videos are taken by the surveillance cameras, they are stored, just in case they may be required in future.
These systems are meant to improve the services that are offered by both the private and the public firms especially in crime management. A camera system may also be used to increase these capabilities. The surveillance services may also be applied in schools and campuses. A single security officer has the ability to sit in the control room and monitor the activities that are being carried out in the entire school through the video system. Some systems may be used together with the surveillance system to increase its efficiency, for example using the access control systems. Access control is mainly used in the sensitive regions. Access control systems that only allow access to the authorized people are mainly produced by the Nova Scotia access control company. This prohibits the entry of other people who are unknown to the institution. The Nova Scotia access Control Company has been providing well trained technicians who can efficiently install the access control systems that suit their client’s needs.
