- 3. INTRODUCTION A surveillance system is called smart when it requires almost no involvement of humans in other words we can say that it has its own intelligence. A surveillance system means the close observation especially of a suspected object. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.
- 4. MOTIVATION Crimes have become a part of our daily life. News articles everyday are mostly of crimes. Theft, robbery, burglary are the most common of crimes. With the progress in technology various attempts has been made to prevent crimes. The most popular technology implemented successfully to prevent crime is closed circuit camera recording. The main disadvantage of this technology is the excessive requirement of memory to store data. So, to overcome this problem we decided to build a model which requires least space to store its data.
- 5. OBJECTIVE To develop a hardware experimental model of surveillance system using PIR sensor. To demonstrate its operation and utility.
- 6. COMPONENTS USED 9V Batteries PIR Sensor Arduino board Bread board JPEG camera Buzzer Few LED Jumper wires Barrel connectors Resistors SD Card USB cables
- 8. THEORY A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation isn't visible to the human eye because it radiates at infrared wavelengths, but it can be detected by electronic devices designed for such a purpose. The term passive in this instance refers to the fact that PIR devices do not generate or radiate energy for detection purposes. They work entirely by detecting infrared radiation emitted by or reflected from objects. They do not detect or measure "heat".
- 9. THESIS ORGANISATION Whenever the PIR sensor detects any motion it sends signal to the microcontroller, which in turn sends a signal to the LED and camera to turn on (at a delay of few milliseconds). The function of the LED is to enlighten the object near the sensor. The camera instantaneously takes photos of the object and sends it to the microcontroller to be stored in the external memory (in this case SD card). Immediately after that the microcontroller sends signal to the buzzer and it gets activated. The action continues as long as the object remains near the sensor. After the object moves away from the sensor the action continues for 15 more seconds after which the microcontroller sends signal to the buzzer, LEDs and camera to turn off.
- 10. TECHNIQUE USED IN PROJECT Our project model is mainly based on the motion detection technique by PIR sensor. The camera gets activated whenever a signal is obtained from the sensor. The entire system is controlled and coordinated by a microcontroller which in our case is ARDUINO (UNO).
- 11. APPLICATION PIR sensors has a lot of applications in real life some of them are as follows: - For security purpose For focusing For counting living beings For temperature measurement etc. Among the above uses our project model is concerned with the security purpose. This model can be used to prevent burglary in houses and offices. In high security places like banks this model can be very useful. Our project has a wide scope of application and modification in future. It can be developed further by addition of several new accessories. For example, the model can be connected to the internet with the help of a router enabling us to get alerts anywhere in our mobile phones. The same can be done by connecting the model to a sim card modem. Alerts can be obtained through the network of the sim card.
- 12. ADVANTAGES Thus I have designed a smart surveillance system capable of capturing video and transmitting to a smart phone It offers reliability and privacy on both sides It is portable because of using mobile technology
- 13. RESULT AND DISCUSSION The complete hardware model of our project is yet to be made. However, an approximate sketch of the block diagram and connection diagram is made which is shown below.
- 14. FUTURE DEVELOPMENT The number of people located exactly on a area and their position can be monitored The voice alarm can be added to this system In future, the devices such as fan, light, TV, washing machine can also be controlled

- 16. CONCLUSION In this surveillance system PIR sensor has been used which is low power & low cost. It have a wide lens range & are easy to interface with microcontrollers. This security system can be implemented in office, shops etc. In addition to this, this system can be equipped with glass break detectors to enhance the level of protection. This is a very low high value system.
