Investigation of Security and Defense System for Home Based on Internet of Things

As the traditional security and defense systems appear some defects, such as wiring problems, higher construction and maintenance expense and delay of receiving alarm messages, a scheme based on Internet of Things is proposed. Embedded ARM9 S3C2440A micro controller is adopted as system master controller, which carries out receiving and processing the transmission alarm message of RF chip worked at 2.4GHz ISM band and searching the alarm message server by Object Name Service(ONS). Alarm message is transmitted on the internet in time by using socket, and the remote terminal will real-time monitor the home security situation. The experiment results show the system obtains expected impressions.
