Security cameras are commonplace in the modern world. Whether in a public space, a private home or a business establishment, video surveillance keeps people safe by monitoring suspicious behavior and is an effective deterrent against criminals.

History

Law enforcement adopted the use of closed circuit television security cameras in the 1960s for criminal surveillance. With the introduction of recording technology in the 1970s, video surveillance became even more effective. Shortly thereafter, security camera use by private businesses and homeowners became popular.

Function

Video security cameras record the area within their vision. Recordings can be watched live or be stored for later viewing via a VCR, DVR or personal computer.

Benefits

For homeowners, cameras provide comfort by monitoring property when no one is home. Reduction in theft and the ability to record a criminal's face leaves store and business owners in a safer position. Law enforcement uses security cameras to survey hotbeds of criminal activity as well as keep intersections and public areas under a discerning eye.

Considerations

It is possible an installed security camera may not be functioning properly. Though the mere appearance of video surveillance often wards off mischief, always remain aware of your surroundings and judge your own level of personal safety.

Warning

Before installing or using a security camera, you should become familiar with all local and state privacy laws.
