Currently, falling prices in technologies associated with surveillance applications has led to a huge increase in their use in all types of environments, although the most common applications are monitoring of traffic and people. In surveillance applications, the majority of the algorithms and applications are based on robustness in the detection and monitoring of people, vehicles, etc., in all kind of conditions, in which power consumption is not a parameter of the system. In this work, we present the use of this technology to develop energy aware light control systems for large installations and to reduce energy consumption. Depending on the architectures and algorithms used significant power reduction is achieved.
