Computer parks often have devices running for tens of hours a week without anyone using them, wasting electricity and money. The issue could be alleviated by shutting down unused systems. However, offline systems are rendered inaccessible to systems administrators for regular maintenance, patching, etc. This study aims to find appropriate methods for shutting down and waking up systems in order to reduce the amount of time computers run inactively, while providing administrators the necessary tools to manage said offline devices. The solution is focused on the use case for UT Delta center.

In light of Russia's aggression in Ukraine, significant developments have occurred in modern warfare, with the adoption of numerous novel technologies and tactics. Consequently, it is imperative for Estonia to keep pace with these developments and create opportunities to defend itself effectively in the event of potential aggression. The aim of this bachelor's thesis is to develop an additional security solution for perimeter protection using electronics to safeguard units during rest periods and to provide surveillance for tactical objects. The developed surveillance system consists of multiple motion sensors, transmitters, and a collector to display the info on a screen. When a motion sensor detects movement, the information is transmitted to the receiver, which then acts according to standard procedures based on the received data. The completed surveillance system comprises of one receiver and three transmitters with motion sensors. Both the hardware and software allow for an increase in the number of components to expand the coverage area of the surveillance network. The devices were tested in various weather conditions, revealing that the range of surveillance may decrease during precipitation.
