The theoretical part presents the project submitter Jablocom ltd. and basic properties of the product – EYE-02. Then there is the introduction to the basic mechanisms of the protocol XMPP, whose understanding is important to build a service that would replace XMPP client for the selected camera. The practical part of the thesis describes selection of the XMPP server and configuration of the XMPP server to ensure the safety of transmitted data as well as the system itself. Then there is a database designed, which is an intermediary be- tween the service and the infrastructure of Jablocom ltd. and WCF Service for adding commands to the database and retrieving and filtering commands from the database. Then there is a service designed and implemented. The service allows to transmit messages (alarms, status messages, errors) from the camera to the IM client of user and to take control command from the user and to display the current status of the camera (watch, sleep). The service has also implemented the basic procedures for transferring files and making video calls via XMPP protocol. There is also main service implemented. Main service checks the runtime of individual fibers in periodic intervals and launches or terminates fibers of selected cameras. Last created application is a webpage that is used to administer the whole system.
