ArticleCurrently 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
