Surveillance systems

Surveillance systems

Surveillance (pron.: /sərˈveɪ.əns/ or /sərˈveɪləns/)[1] is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting.[2] Surveillance is therefore an ambiguous practice, sometimes creating positive effects, at other times negative. It is sometimes done in a surreptitious manner. It most usually involves observation of individuals or groups by government organizations (though there are some exceptions, such as disease surveillance, which monitors the progress of a disease in a community without for that matter directly observing or monitoring individuals).
The word surveillance is the French word for "watching over"; "sur" means "from above" and "veiller" means "to watch". The inverse (reciprocal) of surveillance is sousveillance ("to watch from below").[3] The word surveillance may be applied to observation from a distance by means of electronic equipment (such as CCTV cameras), or interception of electronically transmitted information (such as Internet traffic or phone calls). It may also refer to simple, relatively no- or low-technology methods such as human intelligence agents and postal interception.

  2. Its not a matter of what you want, its how are you going to feel safe. Outdoor security cameras are an ideal, less expensive way to give you the feeling of security you want and need. outside security cameras
