Video Surveillance System – The Perfect Device To Prevent Dangerous Crimes

Posted on 04:38 by Unknown

Digital video surveillance systems and other video surveillance security systems are a great security measure for any office, as they help to prevent and detect crime, and catch criminals. A surveillance video system is a deterrent for anyone wishing to commit any crime in the premises. 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.

The varied uses of video surveillance systems

The video surveillance market is estimated to grow to about 3.5 times in 2013, when compared to what it was in 2006. The growing need for need for surveillance security camera systems across a number of industries coupled with the huge advancements in technology is what has spurred this growth. Listed here are some of the main uses of video surveillance security systems.


To monitor activities


Monitoring activities is one of the biggest uses of a video surveillance security system and is in practice across a number of industries. Prisons use security cameras to monitor the activities of its inmates so that they are aware as soon as someone is trying to incite trouble or trying to escape. Defence organisations also use such systems to monitor activities at their establishments, to ensure that their know-how is kept secure. With the rising incidence of teenage violence and other crimes, schools and universities also see merit in installing such devices for surveillance purposes. Surveillance cameras are also used in hospitals, psychiatric institutions or rehabilitation centres to observe patients who require constant monitoring or supervision, without the supervisor having to physically be in the same room.


To prevent theft


The retail industry is probably one of the biggest surveillance security system users for the purpose of preventing theft. Cameras are installed at retail stores and activity can be monitored on a screen. This brings down the incidence of theft, as people know that most retail stores today use such systems.


To prevent terrorism


Terrorism has become a major concern across most countries, and as such, establishments that are considered potential targets for terrorists - generally areas with large numbers of the general public - such as airports, hotels, malls, hospitals and theme parks are well advised to have a video surveillance security camera system in place. This helps activities to be monitored. For example, if someone leaves a bag unattended for too long or someone is engaging in other suspicious behaviour, security personnel can be immediately dispatched to the spot to investigate.
