Development of a Motion Activated Security Cam for Monitoring Applications

Abstract

The need for motion detection surveillance has become a vital necessity in security systems due to the frequent and widespread cases of theft in the given location. Recently, closed-circuit TV (CCTV) can be seen in many places for particular users to monitor and record the situation in a restricted area. Most CCTVs have to continuously record the incident even when no motion is detected, thus requiring a large memory to store the video. In addition, some CCTVs still use cable installation to transfer video recordings to external storage. The use of cables requires high maintenance costs as they need to be maintained periodically to prevent breakage. Therefore, the project proposes a wireless security cam system that can effectively monitor the attendance of human movement and moving objects in real-time through mobile applications. The system consists of a passive infrared (PIR) sensor and ESP32 CAM embedded with the Internet of Things (IoT) technology. IoT is the main factor behind the changes for this monitoring application system with an embedded sensor. PIR sensors can detect the motion of either humans or animals crossing a particular area within a distance radius of up to 7 m. When motion is detected, a signal is sent to the ESP32 camera to capture an image. Then, with the advancement in technology, the image captured is sent to a Telegram messenger app through Wi-Fi and monitored via smartphone or web browser. This wireless surveillance method provides an effective monitoring system that can send the captured images and alerts immediately regarding any occurrence from anywhere in real-time. Moreover, this project strongly supports the security of all private premises, residences, banks, factories and offices because the users can take immediate necessary action in the case of emergency conditions.
