Abstract
This paper details the design and development of Wi-Fi connectivity based on home security surveillance camera using Raspberry Pi and an IoT Module reducing continuous human monitoring and controlling with enhanced performance and effective results.Adding wireless fidelity to embedded systems will open up various feasibilities such as worldwide monitoring and control, reliable data storage etc. This system comprises of wireless sensor nodes and a controller section for surveillance. Remote user alerts, live video streaming and portability are the prime features of the system.Modular design is followed so that any number of nodes can be added or removed; data acquisition is used to sample signals and measure real world physical conditions. The user is warned via e-mails, phone calls or SMS after an unusual behavior is occurred and an event notification is sent which shows the events captured by the camera. The IoT module eliminates the need of a microcontroller and wireless transceiver module in sensor node, thus it makes the node compact, cost effective and easy to use. The biggest advantage of the system is that the user can seek surveillance from anywhere in the world and can respond according to the situations.
Highlights
The motion sensor detects the change of activity in the video by analyzing it with a python script[1], if there is any difference in the video from the most recent frames, it would alert the user by snapshots and video recordings
This paper[6] proposes the design and implementation of mobile fire alarm system which uses wireless sensor networks; it is defined as a combination of large sensor nodes where each node can sense, process and communicate with its peers so as to work in an efficient manner
The proposed paper[7] puts forth a design and implementation of a home surveillance system using on an embedded system along with multiple ultrasonic sensor modules, which helps the system to perform efficiently as well as makes the system reliable
Summary
In the 21st century where the crimes regarding the invasion of someone else’s property and robbing, stealing and much other antisocial behaviors has reached its peak, ensuring safety and security has an inevitable significance. Adding Wi-Fi to security systems enables faster data transmission and it will help the user to monitor and control the systems globally. Adding to all these features, the IoT module eliminates the necessity of a microcontroller or a computer and wireless transceiver module in a sensor node, it makes the node portable, compact, cost-effective and easy to use. The creation of web servers helps the user to view the sensor status and the live video. This system sends intruder’s picture and the captured video to the owner by e-mail.
