3G Wireless Video Surveillance System Designed for Bus and Reliable Network Transmission

摘要

This paper presents a 3G wireless video surveillance system solution. The system has four cameras collecting real-time information compressed by MPEG-4 inside and outside one bus, then the information will be sent to the monitor center through 3G network. The system corrects video data with LDPC codes, and uses LDAP managing bus and cameras information in the terminal. Experiment shows that the monitoring side can get CIF format video signal at rate of 9 frames per second, under the Gaussian noise, the average PSNR value of the corrected video increases by almost 10dB.
