| Summary: | Intruder detection in a protected zone can be performed by the physical protection which acts within the object's perimeter and survey's it (patrols, monitoring screens of CCTV systems, etc.), but intruder detection can be also done using active protection elements. Active protection elements include alarm systems (electronic safety and distress alarm systems, CCTV security systems, system for control and management of inputs, portable alarm systems). These can be subdivided based on the area in which these elements detect the intruder into following categories: ones which detect the intruder at a certain point (such as object protection systems), at a certain level, where the intruder must cross a boundary between zones on his way through the detection zone (e.g. perimeter protection systems) and in area when crossing the detection zone (e.g. area protection systems). The development of camera systems allowed for introduction of additional functions, such as automatic intruder detection within the protected zone. Using a single protective element (within a camera system) it is theoretically possible to perform various functions - motion detection, survey and check and analysis of events (security incidents). In electronic security systems, an alarm has to be verified using at least two detectors, a camera system or physical protection. That's why CCTV camera systems are currently a very interesting and often utilizes way of securing an object. The article describes part of the research focused on finding out the probability of intruder detection in a protected zone. The authors focused on the influence of changes in parameters of the camera system on the video-based detection abilities. The article cites results of experimental testing which aimed to verify whether the changes in camera system parameters influences the motion detection success rate. This experiment also confirms information provided by a questionnaire survey performed among manufacturers of security camera systems. The experimental tests performed took into account the requirements placed on them by European technical norms. |
