Abstract: With the constant development of the embedded technology and mobile communication technology, the application of intelligent mobile terminal equipment for remote monitoring has become a hot spot in the research field of network monitoring. A multifunctional video surveillance system based on the Android smart phone is designed in this paper. In the system, three layers of the video acquisition terminal, Android smart phone client, and Web server are designed. In the video acquisition terminal, videos are collected by the network camera, compressed according to the H.264 standard, and then transmitted to the server for real?time storage. Meanwhile, environmental parameters and personnel intrusion information (if there is any) are collected by sensors. The communication between the client and the server is established by means of the TCP/IP protocol, so as to realize real?time video surveillance, monitoring data query, and alarm and message prompt of suspicious circumstances. The results of the comprehensive test show that the system has a high real?time performance and flexible deployment, can obtain clear and stable monitoring images, and meet the requirements of remote video monitoring in wireless network environment.
