Abstract: Surveillance is a key aspect in security scenario in existing world. The existing systems consist of continuous monitoring and recording of the scenario or area under surveillance. This causes considerable amount of power expense and unnecessary data recording. To counteract these two problems we propose here a system which has an energy harvester and intelligent power saving technique. The proposed system consists of an PIR and a proximity sensor placed in the line of sight of the camera. When any kind of anomaly is detected in the foreground of the camera, the camera is powered on by the energy harvester unit to turn on the camera. Once the foreground is cleared of the anomaly the energy harvester unit stops the power to the camera and shut down the camera. This helps in significant improvement in power saving and longer battery life in wireless sensor network. The image process techniques use the background subtraction to detect the geometry of anomaly. The proposed method also has renewable energy production system with a solar panel and a energy management unit for charging and discharging unit. The total system will have codes written in MATLAB for the blob analysis of image acquired. The frames will be analyzed by MATLAB for same. The proposed system offers significant improvement in power saving in image acquisition
