The aim of this project is to develop an integrated system for centralised monitoring and management of critical infrastructure systems in residential and commercial facilities. Critical infrastructure systems include heating, cooling, ventilation, lighting, power supply, fire protection, fire alarm system, video surveillance and access control. These systems are mainly installed as separate systems in buildings and their management is rather complex, as each system needs to be managed separately without the possibility of communication and interaction between them. Since they belong to the same building, they should form a single unit for technical supervision of electrical and mechanical installations on the building.
