Video surveillance on mobile devices for sensor network

This paper describes an autonomous monitoring system to supervise environmental parameters such as temperature, humidity, poisonous gases concentration, etc. This system is designed as a set of sensor nodes connected via a wireless network. Video surveillance is used for scenarios where emergency situation occurred. Video stream can be viewed on a personal computer (PC) and on a mobile device. The full-scale sensor network includes the sensor nodes, main coordinators, back-end users, and a camera. The graphical user interface (GUI) based on the sensor network supports an operator to make a decision such as evacuation of the personnel or call to a fire station at an emergency situation. The implemented system is designed to operate autonomously in real time.
