The field of security and surveillance systems is changing fast. This is because of the fact that it has to conform or adapt to the changing strategies of unscrupulous people who seek to profit from by committing crimes against persons or company property. In very large companies security measures are being set up like the installation of CCTV camera systems, even small business enterprise are also jumping into the security bandwagon by also installing their own security systems like remote CCTV cameras, intruder alarms. For companies with very large number of employees and those who deal with several high profile transactions, access to certain levels of the building is imperative to be controlled or managed, because of the fact that large companies has the need to protect its investments and it has to protect itself from corporate spies, especially nowadays that the economy is dwindling that competition between companies are really stringent. To provide peace of mind for the corporate executives that not everyone has access to all of the buildings rooms and areas the access control system must be incorporated with the buildings’ security systems and couple that with the CCTV camera system makes it a formidable security and surveillance systems.

The Access control system is a security system that controls or manages entry or access of people over certain areas in a building or over a network. One typical example of an access control system is a door with lock that only allows people who has the key to unlock the door and enter the area or room. But the world of access control system has evolved so much that it now incorporates several technologies. The integration of electronic technology brought about the development of the biometrics access control system, the key card access control system among others. The biometrics access control system utilises the unique physical characteristics of a person such as the eyes and fingerprints to be evaluated and be used as basis on whether that person is recognised to be having access to that certain level of the company building, a technologically advanced security feature that tags along with a hefty price. The most common access control system is the key card access control systems. This is popular or common due to the fact that it is cheaper and it is proven to restrict access. The key card access control system uses a pre-programmed key card that will determine the access level of a  certain employee. The key card will only open or allow access as far as the level it is allowed to access. The key cards are provided to the employees and are programmed according to their access level. The key card will have to be swiped on to a recognition system which would then be access the computer database and determine whether or not that key card is allowed to access that specific level.

With the number of employees and the number of possibilities that giving access to all of them to areas that are not actually of their concern will increase the risk of company breach of security that is why along with the CCTV systems there should also be an access control system installed in your company building.
