In this paper we have to design and implement surveillance system by use of smart sensors like ultrasonic sensors and pyroelectric infrared sensors (PIR) to detect an intruder in a home, ATM, Industries, Bank Locker room or a storehouse. The PIR sensors are placed on the ceiling, and the ultrasonic sensor module consists of a transmitter and a receiver which are placed vertically on the wall. We are going to use the camera to capture images of the people those are coming under the surveillance area. And we are sending these images to authorized and related personnel via email to avoid the storage cost. This system will also help to reduce the power consumption.
