Laboratory stands for research of security systems’ components

The article presents two laboratory stands for research of basic security systems’ components. PIR detectors are the most widely used components in alarm systems. PIR detector element is a pyroelectric detector — its parameters determine the sensitivity of the detector and its resistance to “false alarms”. The completed laboratory stand allows for a comprehensive study of pyroelectric detectors, including work in a wide temperature range — to protect peripheral objects. The stand consists of radiation source (calibrator), the mechanical modulator, Peltier (change of temperature detector) and measuring instruments.The main purpose of access control system (ACC) is the selection of access to a wide variety of objects and technical systems. Realized laboratory set consists of 4 individual stands KD. Single stand KD is controlled by the transition controller module and base element is the door module. Depending on the desired configuration of the door module is equipped with: a smart card reader with keypad, Dallas chip reader, opening button or keypad. The access is defined for users — we have a weekly schedule, day and so-called time frames.[b]Keywords[/b]: pyroelectric detector, environment studies, access control syste
