Processing Alarm Notifications Algorithm of Security System Object Equipment for Reducing the False Alarms Level
Problem statement. Nowadays, the main means of security alarm object complexes of the protected objects are integrated security systems (ISS) based on addressable two-wire lines. ISS management is carried out using specialized software, which allows to use more sophisticated algorithms of technical security equipment processing alarm and service notifications (TSE) to reduce false alarms. The purpose of the paper is to form a processing alarm notifications of object security alarm systems algorithm to reduce the level of false positives. This algorithm is designed to assess the connection between the security alarm detectors activation and unauthorized access (UA) to the protected object facts effected by the offender. It is proposed to determine the connection between the security detectors alarm notifications and unauthorized access facts based on the knowledge of the topology of protected offices, the security facilities of the object, the types of elements of building structures. The time parameters of the alarms are used to provide this connection. The proposed algorithm does not reduce the total number of alarms, but allows the security service not to respond to part of the alarms which are unrelated to unauthorized access. Methods. To develop the alarm notification of security system object equipment algorithm formation standard methods of system analysis, theory of algorithms and expert estimates are used. Novelty. The novelty of the presented solution lies in the creation of a new processing alarm notifications algorithm of security system object equipment. Also the novelty of the work lies in the formation of databases of offender time delays expert estimations when structural elements of engineering and technical strengthening are crossed and of offices intrusion detectors of various types overcome (sabotage) durations. Result. The processing alarm notifications algorithm of security system object equipment for reducing the false alarms level is developed. Practical relevance. The developed algorithm can be implemented as a software add-on in existing software complexes of the automated workplaces of the indoor security alarm systems based on addressable two-wire lines.
