Abstract:

Currently it is highly important for detectors to be able to achieve efficiency, reliability, and faultless operation, and to be ergonomic thanks to their assembly and being easy-to-fit. In the case of a proposal for the placement of detectors it is naturally important to determine position of the detector and the type of detector being used, but also to guarantee their capability to be able to detect anything when in use and their user and installation-friendliness. The problem of passive infrared (PIR) detectors affects a large proportion of intrusion and hold-up alarm systems (I&HAS). In a time of increasing property crime, it is highly important for PIR detector to actually be able to detect break-in attempts within the guarded area on a reliable basis and free of error. In the case of the installation of PIR detectors, it is naturally important not only to ensure correct installation, to gauge the external influences which may impact upon the detector and to ensure proper maintenance, but also to guarantee the capability of detection under more arduous conditions. The tests and comparisons which have been conducted examine both the normal operation of the PIR detectors and the ergonomics of these detectors. These tests are important both from an informative perspective and due to the opportunities to be able to develop potential counter-measures which could lead to their improvement.

Abstract:

The problem of security methods affects a large proportion of intrusion and hold-up alarm systems (I&HAS). In a time of increasing property crime, it is highly important for the security methods of livestock buildings to be able to achieve efficiency, reliability and faultlessness. In case it is proposed to place detectors, it is essential to determine the position of the detectors, the types of the detectors, but also to guarantee their capability of detection for use in livestock production buildings. The security proposals, which have been conducted, examine both the normal security methods in livestock production as well as cost and long-term financial expenses (investment in the communicator, private security guards etc.). These security proposals are important both from an informative perspective and also because of the possibility of using individual proposals in securing livestock production in practice. The aim was to compare the two kinds of security methods for a livestock building object. The compared values become the acquisition costs of security system.
