ABSTRACT As an essential constituent of many associations’ security and safety precedence, surveillance has established its importance and benefits numerous times by providing immediate supervising of possessions, people, environment and property. This project deals with the design approach of an Embedded Real-Time security System Based Raspberry Pi SBC for intruder observation that reinforces surveillance technology to provide essential security to our life and associated control. The proposed robotic unit is used for video surveillance of remote place as well as remotely control of the unit using Bluetooth as medium. Raspberry pi serve the purpose of server as well as the microprocessor for the system. An embedded web server creates an easy way for monitoring & controlling any device which is at remote place. The proposed security solution hinges on our novel integration of cameras and obstacle detector into web application. Raspberry Pi operates and controls obstacle detector and pi camera for remote sensing and surveillance, streams live video and records it for future playback. This research is focused on developing a surveillance system that helps the property owners to monitor the place to avoid intruders by using pi camera and wireless Bluetooth technology for remote control. This Raspberry Pi based Smart Surveillance System presents the idea of monitoring a particular place in a remote area. The proposed solution offers a cost-effective ubiquitous surveillance solution, efficient and easy to implement. The proposed system can be used in military applications just by adding few sensors like infrared sensors so as we can detect the movements. In health care applications the proposed system can be used just by changing the design the robotic unit.
