Electronic security need :-
The ability to monitor movement and identity of visitors both day and night is an important aspect of security in today's living. Protective action helps to anticipate and take appropriate remedial action. Incidentally, when people know that their movements are being monitored, they tend to be more compliant with prescribed guidelines and instructions. Electronic security systems installed in homes, condominiums, factories, malls and other public places help in crating such a formidable deterrent.
In today's complex society, there are many factors that necessitate an effective security and safety system for protection of assets. Three key factors govern the planning of asset protection. Effective planning designed to prevent losses, countermeasures to limit the losses and to limit unpreventable losses and support for the protection plan by the senior management. Systems are most effective when integrated with other security hardware and procedures to form a coherent security system and team which can protect and be responsible for the assets of an organization.
The coverage of critical areas and operation during an emergency can save considerable money. Documentation provided by recordings of assets lost or stolen or personnel injuries or deaths can support 'nonnegligence' and show that a prudent emergency and disaster plan was in effect prior to the event.
In designing a security system, any element chosen should be analysed to determine how it will contribute to prevention of loss or protection of assets and personnel. Functionally, an integrated security system can be regarded as a design coordinated combination of equipment, personnel and procedures which utilises each component to enhance the use of every other component and assures optimum achievement of the objective.
For example, if an intrusion occurs, at what point should it be detected and what should be our response? And if there has been a violation of some of barrier or fence, the intrusion detection system should be able to determine that a person has passed through the barrier and not an animal, bird, insect, leaves and debris. The synergetic integration of electronic system and manpower security into a system increases the overall security of the facility and maximises asset protection and employee safety.
The role of the electronic security system is to provide an early warning of any attempted intrusion in order to minimize damage, pinpoint the location of intrusion and lastly to ensure a more effective manpower response. The systems that are employed to enhance the security are intruder alarm systems (external and internal), CCTV (closed circuit television) and ACS (access control systems).
Each type of system has its own particular role to play and has been developed by the security industry to minimise particular security risks. For example, intruder alarm systems usually secure unoccupied premises and are manufactured to standards to eliminate false alarms as far as possible. External intruder alarm systems are usually installed at large sites where intrusion into the grounds must be detected before access to any building has been obtained. A guard force that operates on the site itself normally responds to these systems. Intruder alarm systems have two roles to play within the security systems for it is both early warning in terms of warning of manpower requirements where and when needed at the scene of an incident and act as a physical barrier as the alarm will sound when the intruder crosses the barrier.
The type of electronic system designed will depend on the assessment of the risk, type of physical structure to be overcome and the time required to obtain the manpower response. It needs to be stressed that manpower and a good physical structure must always be present in an integrated security system.
CCTV system is basically an extension of an operators own vision be it for security or any other function. As far as security is concerned the employment of CCTV within a system means more 'ground' can be easily viewed and therefore controlled resulting in a more efficient use of manpower. Apart from day and night general surveillance, systems are now being used very effectively to provide perimeter detection through video motion detection systems and remote surveillance through CCTV systems.
Access control systems are designed to allow only authorised entry with the premises and as such form an aid to the physical barriers as manned access control does on a gate or door. Its secondary design features provide easier security locking procedure during unoccupied periods. Access control points are unmanned and since the systems may be abused in a number of ways, it must incorporate some form of alarm system. This means that it also plays a part in the role of early warning.
