Abstract:This paper proposes a scheme of remote monitoring and alarm functions for home security subsystem by using ZigBee technology, image capture and compression technology and network transmission technology. It introduces how the system is designed and how it works generally. The overall block diagram design of the system, hardware platform of Anti-theft alarm subsystem, embedded software platform as well as diver programming have all been realized. Furthermore, the designed has improved both the image acquisition process and the programming of workflow for ZigBee. It turns out that users can remotely view image/video of the abnormal point to take further action when the system audible alarms and notifies the users at a certain time that detects an abnormality which makes it has practical significance.
