The main topic discussed in this dissertation is the implementation of a web interface into DSC NewPower series security panels which are currently popular on the Slovenian market. Due to the rapid development of World Wide Web and the variety of telecommunication services, there is almost an unlimited number of products which support interaction through internet from almost any place in the world. Web access to a device via web browser on PC or an application on smartphone has become a necessary feature of any product including security systems. The most important is the information which users get through the internet, however an interaction with the device is immensely beneficial as well.
This dissertation covers the analysis of the current situation of security systems. We analyzed actual solutions for the remote access to DSC security systems, their advantages and disadvantages and described them in the opening chapters. Based on the gathered information we presented the user demands for a security system which includes a remote access guidance. Furthermore, we identified technical requirements for implementing our solution based on a microcomputer called Raspberry Pi. The used hardware and software technologies are presented in the chapter Predstavitev uporabljenih tehnologij and their implementation is described in chapter Implementacija spletnega vmesnika. Due to the fact that this device will be used in residential security systems, the programing code for key components was omitted for safety reasons. The implemented solution was tested by 11 already existing users of DSC security systems. Testing description and result analysis are included in chapter Testiranje in rezultati. We may conclude that the hypothesis about the necessity for a remote access to a security system is one of the basic demands of a modern user. The biggest advantage of our solution is safety, which has been confirmed mainly by users of module EnvisaLink. The second biggest advantage were additional features of our solution, which has been confirmed by other users. It was claimed that the biggest shortcoming was, in particular, the fact that the idea has not been developed completely and thus some of the components could not yet have been included. All of the respondents described the layout and functionality of the web interface as simple and transparent, where a user can quickly find the desired information and functions. Since the solution is not yet finished, we are fully aware of the need for further development and upgrading as described in the final chapter of this dissertation Zaključek in prihodnje delo. In further development, such as sending notifications via e-mail, controlling additional outputs on control panels, integrating the CCTV system and developing applications for each mobile platform, we will take into account all the suggestions from the respondent users. Further development will also require regular updates of every component of the microcomputer Raspberry Pi, which will provide greater security and reliability of the system.
