As part of research and development work at the Department of Security management of the University of Zilina, we concerned ourselves with testing various types of motion detectors. Testing of detectors in general serves to acquire a basis of data for software developed at the Faculty, which serve to measure and evaluate the levels of physical security of an object. Detectors are tested at the faculty in terms of reliability and breach resilience. We are mostly interested in the time it takes to detect an intruder. Until now, we have not tested several detectors at once. Testing of a larger pool of detectors at the same time is useful when comparing their detection capabilities and when testing the ability of the alarm system control unit and its load capacity. The article contains a concept, design, blueprint and principle of operation of a testing device, designed to test a greater number of passive infrared motion detectors at one, works. The designed testing device allows for testing the detection ability of several motion detectors at once, compare the time it takes them to disconnect their NC contacts and also compare the reaction times of individual motion detectors. The article also contains a description of the device’s structure and recording of the acquired results which is based on a free Arduino platform and their usability in practice. The proposed device will be further improved as part of our R&D activities.
