Cover Story: A Smart Intercom System allows residents to use instant messaging software of smartphones to replace the handset function, and there is no need to install and learn how to use new apps. Residents can still check the statuses of their doors through the system when they are not at home. Any visitors can also contact residents through this intercom; there is no way to confirm whether residents are at home, which enhances houses’ security. The system architecture strikes a good balance between user convenience and home security, as well as between performance and cost, effectively improving home security and reducing costs.
