A one of the major key factor in home security is intruder detection. Due to the development of technology, cloud based intruder detection system has become more efficient and trustworthy. The proposed system in this research article suggests the use of cloud connected to Node MCU along with the IR sensors, LCD screen and buzzer. Advantage of this proposed system is that the user can access and control the security system from any remote place using Web browser or mobile app because this system is cloud based. When compare to traditional security systems, the proposed cloud based intruder system has many advantages like real-time notification if there is any security breach and the remote access to the system. The proposed system can be configured to get notification in case of any security breach. The difficulties faced during the creation and implementation of this system are discussed in this article. Solutions for these to get beyond difficulties are also discussed. The report also offers the outcomes of testing the system’s functionality, including its reliability of the cloud-based monitoring and control system and its accuracy in detecting intruders. Overall, this study shows how IoT-enabled smart intruder detection systems hosted on the cloud might improve home security. For homeowners seeking sophisticated security features, the system offers a dependable, effective, and economical solution for protecting residential properties.
