A crucial aspect of assuring safety for public areas is the possibility to effectively supervise them. Variety of monitoring systems are being employed for that purpose, but many of them need to be accommodated by local infrastructure. It is not always possible however, and necessity to monitor them arises occasionally for a limited periods of time. A solution is a system that can be deployed in field and operate in various weather conditions. Thermal cameras can be used during night and low visibility conditions like mist without need for additional illumination. Designed system consisting of such cameras will use internet of things technology for internal communication, eliminating need for extensive networks of cables and speeding up configuration and installation by automating protocols. Primary role of this system is to monitor area of interest for movement, emergencies, inflow and outflow of people or sabotage attempts. The system will use a network of miniature thermal cameras with 80x80 microbolometric sensor. Cameras will be equipped with geolocalization sensors and will be able to operate independently for at least 2 days without external power source. The system will monitor area and detect presence and movement of people and vehicles at certain distances. The system will be supplemented by other sensors like PIR, acoustic or seismic sensors. System will be placed as dispersed mesh configuration, what enables scaling or fast deployment via airplane drops.
