Abstract

According to people’s requirement for video service and combined with the WAPI (WLAN Authentication and Privacy Infrastructure) standard design a WLAN video communications terminal. The design adopts the Freescale Company’s i.MX27 as the main control chip, including video input and output module, power management module, audio input and output module, memory module and baseband transmission module. This design makes up the WLAN video communication equipment shortage in market, and greatly improved the safety of video communication, while this design can also be used in residential surveillance, network cameras, traffic monitoring, etc.
