With the rapid development of the mobile communication technology, multimedia transmission over mobile network has become a hotspot in the monitoring area. We propose an application of the embedded Linux system and CDMA1X wireless data transmission technology in the video surveillance system. It is also a general model of wireless video capture and transmission based on embedded Linux and CDMA1X network. By using CDMA date communications technology, H.264 digital video compressed encoded and decoded algorithm and RC4 encryption mechanisms, the system can achieve efficient collection, encoding, encryption and transmission processing of the real-time video signal. It can be widely used in public security, fire protection, transportation, finance, news gathering, and other fields.
