Design and implementation of embedded wireless video surveillance system

To solve the problems of inconvenience and inefficiency in the current schemes of video monitoring system,a wireless video monitoring system was designed based on ARM-Linux.First,the Linux was altered to adapt the embedded hardware platform.Second,the interface functions of V4L(Video for Linux) were used to implement the video collecting.Then,the video data was encoded by the newest video coding standard H.264.After these,the encoded video data was packaged by RTP/RTCP(Real-time Transport Protocol) protocol and transferred from the wireless network.Lastly,DirectShow was chosen to implement the video decoding at the remote client.The experimental result shows that the video obtained has high quality of compression and little distortion,which indicates that this solution suits for real-time video monitoring.
