Video surveillance can be
defined as observation or scrutiny of a particular site for security and business purposes. Video
surveillance cameras have become popular because of the ease and simplicity that they provide when
it comes to security surveillance. There are different varieties of video surveillance cameras that
include CCTV cameras, CCTV accessories, and video security systems.
Other types of cameras include
dome cameras that can capture video images in a 360-degree angle, bullet cameras, day night
cameras, infrared cameras that can capture images at night, vandal proof (unbreakable) cameras, and
hidden cameras. Video surveillance cameras are used in shopping malls, police cars, parks and other
public places, companies, and in banks and ATM machines.
Video surveillance has become an
integral part of businesses and law enforcement agencies that use these cameras extensively. The
images and videos captured in a video surveillance camera are admissible in court as evidence. This
makes them indispensable for law enforcement agencies and security agencies around the
world.
New inventions in this field
such as digital video cameras make it possible for businesses to study customer traffic and monitor
any site for security without human intervention. Digital cameras are also available in "smart"
models that are equipped with motion detection software that captures any movement that is untimely
or is unusual.
Many criminal cases have been
successfully solved with the help of these cameras and the ever-changing technology only augments
the usefulness of these in the law enforcement field. Days like black Tuesdays would have been
avoided if proper surveillance were carried out in the airport. This is the main reason that
airports and other transport sites have beefed up security by installing such smart video
surveillance techniques as digital video cameras.
Video surveillance is becoming a
business and security tool that is proving to be indispensable for scrutinizing and analyzing
customers and delinquents alike. As the IT sector experiences a boom, video cameras are the
auxiliary components that are becoming cheaper and more advanced.
