Security is one of the major issues at present world. So, we proposed a security patrolling robot. In some situation CCTV camera will not be a preventive measure for security-based activities since it only focuses on the event and doesn’t provide any prior message. In our security patrolling robot, it covers some certain area, if it detects any unwanted activities, it sends warning to the user. This security patrolling device use camera and mic that is fitted on the vehicle for security. It analyses every nook and corner and detect the issues using the camera. It detects the sound caused by the problem and move towards it, then it inspect the area to see if any human faces are detector. It gives constant observance together with live transmission of the site of crime.
