Process of ensuring the security of citizens, objects and material goods requires access to the information from sensors located in diff erent points of monitoring and data acquisition systems. Th ey are a widely used in administration of carfleet or the visualization of selected functions of transport processes. However, transmission of data from multiple video sensors may lead to the degradation of video quality and even to lack of identification capabilities. As a result, the overall service reliability can be decreased. The process of the system exploitation can determine the reliability of the video monitoring services as well. This process includes the technical object (hardware and soft ware) and the man (operator) who exploits the system under certain environmental conditions (external and internal) and represents so called antropo-technical approach in which the operating requirements are taken into consideration (particularly related to reliability). The paper presents components elaborated for maintenance of reliable video monitoring services as well as the results of selected tests showing its efficiency. Proposition of comprehensive metrics for assessing the reliability of exploitation of video monitoring system, which takes into account antropo-technical approach is presented as well.

The paper describes Trigger and Data Acquisition (TRIDAQ) systems of accelerator experiments for High Energy Physics. The background for physics research comprises assumptions of the Standard Model theory with basic extensions. On this basis, a structure of particle detector system is described, with emphasis on the following functional blocks: Front-End Electronics, Trigger and DAQ systems. The described solutions are used in the LHC experiments: ATLAS, ALICE, CMS and LHCb. They are also used in other accelerator experiments. Data storage and processing functionality is divided into two hardware systems: Trigger and Data Acquisition, that are dependent on each other. High input data rate impose relevant choices for the architecture and parameters of both systems. The key parameters include detailed system structure and its overall latency. Trigger structure is defined by the physics requirements and the storage capability of DAQ system. Both systems are designed to achieve the highest possible space and time resolution for particle detection. Trigger references are reviewed [1]–[39] as well as chosen accelerator research efforts originating in this country [40]–[83].
