The biggest trouble that a government faces apart from the economical crisis is the act of the criminals. In order to control the number of such acts even though completely stopping them is virtually impossible for the government, surveillance systems are deployed. The surveillance systems ensure that the police can have a close look at the crime site and can help catching the criminals. The need of surveillance systems is in each and every office since each office has their own private area that has to be safe guard from the thieves and criminals. Even though in most cases it is the government that uses these cameras deployed in the public areas like the subways, parks and streets, the private sectors are also using them lately to reduce the occurrence of the crimes. The security cameras systems are deployed in every hotels and apartments that you look around from the event of robbery. The security camera systems not just help in the case of robbery and other crime but in some cases can help in giving a clue to incident like a fire accidents.
The security camera systems are made a mandatory across every streets in the western countries like the United States and the Europe by the government and it is also been part of every important public places across the developing and under developed countries. The security camera systems are widely used in financial organizations and shops since they are the one that are often interrupted by the criminals than the houses. The security camera systems are been the most helpful witnesses in number of cases and has served in solving numerous cases and catching the actual criminal.
A survey across the different countries in the world proves that the countries with good surveillance systems are the one that has a lesser amount of crimes recorded than those who do not have surveillance systems or with poor surveillance systems. It is also to be noted that the usage of a surveillance systems also requires a good subsystems like a good storage capacity and a good transfer medium. Since the image captured has to transfer to a local device and the details have to be stored, it needs a good storage device. For a continuous video coverage to be stored in a storage system it needs very high capacity hard disks in the case of a normal video coverage since the security camera systems cannot afford such high storage systems, it has to be compressed and changed to digital forms for lesser memory.
In some cases, the coverage of incidence requires a more secure way of covering and capturing the criminals. These types of cameras are named as the hidden cameras and even though they do not directly come under the surveillance systems, they do serve an important role in bringing out the criminals. These types of surveillance cameras are used by the media persons for operating stings and bringing out big personals like the politicians and sports persons to the media and punishing them for their offence.
