Cameras and recording/control devices connected thereto are widely used in any location that needs to be monitored for various purposes. Although the most important objective of video systems is to monitor or to be warned instantly by alarm systems for monitoring occurring incidents for response, it is also possible to inform of incidents and obtain evidence pertaining thereto in later times by watching the records already recorded.

Use of cameras started to be widespread for security and non-security purposes in a number of sectors.
