Design of wireless video surveillance system

Abstract With the rapid development of the Internet of things technology, the rapid development of the semiconductor industry and the continuous enhancement of people's awareness of security, wireless video surveillance has come into people's production and life。 Compared with the traditional wired video surveillance, wireless video surveillance by virtue of the advantages of low cost, flexible networking, stable performance and so on toward the direction of transmission monitoring digitization, network and system integration of rapid development。

This design based on AR9331 chip with embedded Linux release version of OpenWrt and WiFi technology, the realization of wireless video surveillance system, mainly including the hardware components and related software development and configuration。 Design points are: 1, the design of the wireless video surveillance system has a low price, high performance, easy to operate features。 2, the design of the OpenWrt system for the open source Linux operating system, with a high scalability, high integration, to provide better support for the extension of the latter part of the function。 3, video capture terminal using WiFi technology AR9331 development board and AP combination, make full use of the WiFi wireless network to facilitate the construction of wireless local area network, the collection of simple and efficient。 4, the client does not need to write specific software, the use of B/S architecture can easily achieve real-time wireless video surveillance, with good practicality and higher value。

This paper has 42 figures, 17 tables, 20 references。
