This project title “Smart security surveillance using IoT”, submitted by Sharmin Akter, Rehana Afroz Sima, Md Sohid Ullah to the Department of Computer Science and Engineering, Daffodil International University has been accepted as satisfactory for the partial fulfillment of the requirements for the degree of B. Sc. In this 21st century, with the gift of the Internet, Internet of Things (IoT) has become an integral part of our everyday life [1]. The user will also be able to see what is happening in front of the door in real time on the Internet.

In the proposed project, a camera module is connected with raspberry PI, a small computer gadget based on Linux platform, to capture the image of the visitor and a video based on passive infrared (PIR) sensor and the button. In the future, additional AI will be added to the system to recognize and identify the visitor's gestures. This is the complete solution to the traditional doorbell problem with increased extra security.

But the problem is that users cannot see who is outside the room or who is clicking the bell. If a suspicious person moves in front of the room, the users of the room cannot know this or are not informed of what is happening in front of the room. The Raspberry Pi single board computer is one of the most popular few other systems ever made.

The Raspberry Pi costs only $25 and can run a full, specially compiled Linux distribution [2].

Problem Statement

Since we use Raspberry Pi, Pi camera, PIR sensor, it is cost effective and stable.

Expected Output

In the second chapter, there is a comprehensive literature review of previous works on security control and its system design and similar other works, home control system and also showing the technical challenges. The third chapter highlights the use case design of the project with a description, block diagram, details of our proposal and our implementation requirements. In the fourth chapter on project planning and implementation with the practical details of our project planning, research and implementation for project testing.

In chapter six, the conclusions and recommendations based on the challenges counted and the possible future development of the project work are counted.

Whenever it detects any movement, it simply takes snapshots, a 3-4 second video and stores it in memory. The first is that the length of the video is not sufficient, and the second is that it does not have any other features, e.g. Daffodil International University 6 The purpose of this is to observe animal behavior where no human can reach.

Since it can detect any type of animal using it, there is no need for human interaction. Power Management: Every IoT system needs a power source and proper power management to operate functionality. Admin will be able to log in and see what is happening in real time in front of the doorbell.

The visitor can press the push button and the notification is sent to the administrator together with his or her photo. But if the visitor doesn't press the button, it will send the notification along with the photo directly to the user. Daffodil International University 10 pins for power, 8 pins for ground and rest 28 pins general input output.

Some other parts of raspberry pi are two 4 USB ports, 1 HDMI port, one WIFI dongle, one port for camera module and another port for headphone [5]. When the guest arrives in front of the room or the doorbell, he will simply press the switch and notification will be sent to the administrator's phone through the mobile application. There is a cover called a Fresnel lens that focuses the infrared signal on the pyroelectric sensor.

There are also two potentiometers, one for adjusting the sensitivity and another for adjusting the time [7]. The original 5-megapixel model was released in 2013, and an 8-megapixel Camera Module v2 was released in 2016.

Plug the VGA or component video cable into the monitor on the other end of the cable into the Raspberry Pi. After a certain period of time if no button is found, click it, then it will just send the notification as suspicious. Insert the Raspberry Pi camera module into the camera slot provided on the Raspberry Pi.

Figure 4.3 shows all components of the Raspberry Pi including GPIO pins, CPU ARM, RCA, audio output, power supply, SD card slot, Ethernet and other parts of the Raspberry Pi. Power: This is a 5v micro USB power connector that you can plug into a compatible power supply. It is risky to use battery power while connected via USB to the raspberry Pi.

When this happens in the range of the PIR sensor, it simply detects movement based on that infrared radiation. This means that the camera and the Raspberry Pi must be very close to each other and therefore limits where we can place the camera. However, it is small and lightweight, making it easy to place as long as it is close to the Raspberry Pi.

Some of the benefits of using a Raspberry Pi camera are that the software for the module uses the RPi GPE, which is the Raspberry Pi's graphics processing unit, and thus uses less CPU. The camera is also quite good; but it has about the same megapixels as the webcam.
