Aim: The purpose of this article is to expose protection issues of key installations. Specifically, as an illustration, attention is focused on questions concerning the security of a maritime port. Within such a perimeter it is possible to identify a range of zones which require diverse protection measures. In turn, this provides a full image of security measures which need to be harnessed to protect key installations.

Introduction: Current technological advances in the field of security systems for key installations afford a multitude of functional and capability solutions. Creation of a security system requires, at the operational level, a need to ensure compatibility in procedures for those engaged in the realization of protection. Security systems for key installations require the engagement of technical measures as well as the services of security organizations. This requires a suitable management approach to individual elements of the system to maximize capability and competence. Additionally, a proposed security system should be consistent not only in terms of procedures, but also with regard to the technical interaction of each subsystem. To achieve this it is necessary to integrate various subsystems at the control center, which is responsible for co-ordination and proper flow of information between those involved in the security activity.

Results: The paper exposed main technical issues relating to key installation security systems, in context of internal and external security. Authors revealed fundamental problems associated with the use of special perimeter sensors as well as long range visual aids which support the work of security staff. Problems were also highlighted about issues concerning integration of systems which should satisfy requirements of operating BMS security systems in relation to external security sensors.

Conclusions: An analysis reveals that the main criterion for selection of system elements used in the protection of key installations is the budget. Clear trends indicate that, in the main, investors chose systems based on visual detection. Such systems, although offering many features, are not ideal for variable lighting conditions. Additionally, they provide a false conviction of reducing the cost of a properly functioning security system. Therefore, it is vital to adopt a security system which satisfies the needs and requirements of given key installation.
