Abstract
Aim: The main purpose of this research was to determine and verify the effective range of Long View 2 camera systems in laboratory and practical conditions. Particularly, the authors endeavoured to determine the distance at which the tested camera could identify, recognize and detect an observed target.
Introduction: Low light vision and fog video cameras have different abilities to record external information. Therefore, the linking of their individual features may significantly improve the ability to detect intruders, emergency incidents or situations which endanger the safety of a target under surveillance. Specially designed for surveillance, multi-sensor detection camera systems facilitate observation at a long distance and tracking of targets with the aid of a pan-tilt mechanism incorporating an optical zoom. All system components are integrated in a single compact housing. The compact design and multi-sensor components allow for the equipment to be used successfully by various security services
Methodology: This article describes a research process used to determine practical application parameter standards, with a special focus on the range for detection, recognition and identification of humans. The article identifies measuring equipment used, procedures and results. Tests were carried out in accordance with established procedures “Parameter measurements of infrared devices”, established by the accredited Testing Laboratory of the Institute of Optoelectronics, Military University of Technology (MUT). The process applied in the research allowed for the determination of parameters such as; the minimum resolvable temperature difference (MRTD), the minimum resolvable contrast (MRC) and the modulation transfer function (MTF). Field tests were performed to verify the capability and usability of cameras in working conditions. Additionally, results obtained during laboratory tests were compared with an objective assessment by the camera operato
Results: Laboratory research and field tests facilitated the determination of an effective range for the operation of the Long View 2 camera system, intended for use in security systems covering a large expanse.
Conclusions: Conducted research and tests have confirmed the effectiveness of the Long View 2 camera system for use in identification of threats and long-range observation of offshore and onshore targets.
