The aim of this bachelor thesis is to create a network security system focusing on compatibility with the widest possible group of IP cameras from various manufacturers and support for remote access to records even from places outside the local network. This problem is solved using two closely cooperating applications. The first application runs on a device in the local network (in our case miniPC Raspberry Pi). The application creates the records by receiving and storing RTSP transmissions from individual cameras. It then modifies these records into a form usable for display on websites and sends the second application from which the user can access them. This application is referred to in the text as agent or agent application. The second...
