Perimeter Security System
The main designation of perimeter security system is to early detect any intrusion to the guarded facility and to further alert the guards in order to take the appropriate subsequent steps.
Perimeter security system ensures safeguarding of the approach ways to an industrial facility or a privately owned parcel of land and is the first line of defense for an object. Due to a number of restrictions, a perimeter security system should be used in combination with some other security systems and alarms (such as video surveillance and intruder alarms).
Perimeter security system can protect not only the insides of industrial or business premises, but also the objects and articles of value located within the guarded area to ensure protection against burglary and vandalism.
There are many types of perimeter security systems nowadays. Each of those systems has its own advantages and disadvantages, and it is therefore very important to make a right decision as to the choice of the type of a perimeter security system for a particular facility.
Any kind of perimeter security system must meet a specific number of criteria:
- Capability of early detection of intruders, which means before they penetrate the facility;
- Exact compliance with the perimeter outlines and no 'blind spots';
- Concealed mounting of sensors of a security system;
- Independence of the parameters of a security system from seasonal and environmental conditions;
- Insensitivity to external factors of 'non-alarming' nature (i.e. industrial interference, noise from transit vehicles, small animals and birds);
- Stability against electromagnetic interference (i.e. storm discharges and sources of strong electromagnetic emission).
Complexity of a perimeter security system depends on:
- type of fencing;
- ground area;
- presence of trees, deepwater rivers, steep rocks, and some other details of terrain.
- Factories and industrial enterprises because they have significant property assets.
- Facilities with large ground areas (i.e. business centers, logistical centers, and vacation hotels).
- Private cottages and country houses.
For absolutely all facilities, perimeter security system may become a waste of money if:
- the cost of such a security system is incompatible with the cost of a possible damage;
- no fast response to an alarming signal is provided; and
- this system is improperly designed and installed.
The main specifics of building a perimeter security system consists in the necessity to consider a large number of details staring from a facility design, the possible attack ranges, possible manners of intrusion, and availability of fencing and its design elements and up to the climatic conditions and the surroundings of a facility. The information on many of those details can only be obtained through onsite research, and this research must be conducted prior to all other operations to safeguard the facility's perimeter. In the course of design work, the following things must be identified: minimum required degree of facility protection; manner and nature of and procedure for the interaction of a perimeter security alarm system and any other instruments to safeguard a facility; paths for and methods of cable installation; etc. Since there are many points of interfacing with other systems, the design work of producing a perimeter security system becomes a complex task.
Successful creation of a reliable perimeter security system with no false alarms depends on how thoroughly all stages of the work are performed.
