This bachelor’s thesis presents the complete development process of a system for theautomatic adjustment of camera zoom on container cranes. Before the developmentphase began, it was necessary to determine how to solve the problem of visualsupervision during crane operation at great heights. The objective was to improvevisibility and operational efficiency in the port, reduce crane operators’ fatigue, andultimately address the challenges associated with working at height. This enablesthe operator to control the crane remotely from a safe workstation at ground level,eliminating the need to work inside the crane cabin located 40 m above the ground.The main contribution of the thesis is a hybrid zoom adjustment algorithm, whichmakes the work easier for the crane operator. The system was implemented using ahigh-performance AXIS Q6315-LE PTZ (angl. Pan-Tilt-Zoom) network camera andthe Python and CoDeSys programming environments. The camera is connected to thelocal network via a UTP cable. Special attention was paid to communication betweensystem components. The Modbus TCP/IP protocol was selected for exchangingposition data between the PLC and the Python application. For video transmission,the MJPEG and H.265 codecs were compared. K
