For any business, video surveillance cameras will make most people think twice
about any criminal activities they were thinking of committing. People know that
a video surveillance system will capture their actions on film, helping to
identify and catch the person responsible for the criminal act.
The first
video surveillance systems to be installed in the USA were CCTV surveillance
systems (closed circuit television) in 1969. These had to be watched by people
during the entire time they were running. When video cassette recorders became
available, video surveillance security systems became even more widely used,
with tapes being used as evidence when crimes were committed.
In the
1980s, video surveillance systems started being widely used in public areas.
Businesses, stores and banks also started using them to deter theft and help in
the apprehension of criminals. Digital multiplexing became widely available in
the 1990s, and many companies and places started using digital video
surveillance systems, which had added features that enabled recording of only
those events that were important.
Components of a Video Surveillance System
The different components of a
video surveillance system will depend largely on the type of video surveillance
system you are interested in purchasing. More complex video surveillance
systems, like remote video surveillance systems or wireless video surveillance
systems, have more components to them than a basic surveillance video system.
Some of the components to a video surveillance system include:
- Video camera or cameras.
- Recording device.
- Internet monitoring software.
- Monitor.
- Time lapse VCR.
- Motion sensors. These record only when motion is detected.
- Battery pack.
Purpose of a Video Surveillance System
There are two main purposes to a
video surveillance system. The first and most important one is to deter crime.
The second is to help catch criminals when a crime has been committed. Some of
the ways a video surveillance system accomplishes both these goals is by doing
the following:
- Monitoring stores and stock
- Providing a visible presence or warning that video cameras are used in the
store
- Recording any crimes that are committed
- Allowing people to monitor the cameras and see what is happening at any time
of the day
- Pinpointing exact times when crimes have been committed
- Providing an identification method, by which people can be screened before
entering a building
- Allowing security personnel to check who is in a building at any time.
