Design And Implementation Of The Remote Video Monitoring System Based On Embedded Web Technology

With the rapid development of Internet technology and embedded technology, video monitoring technology has developed a new stage. Quickly, the video monitoring system based on embedded Web technology has become a primary development direction of monitoring industry in the future, applications of which are gradually shifting from large public spaces to small private spaces. With the faster life pace, people’s time and energy of taking care of the family are very limited, and the problem of population aging is getting worse in China, which increases people’s attention to the family. For this reason, people hope to timely handle emergencies when they are having a business trip or travel.Combined with embedded technology and Web technology, this paper proposes a remote video monitoring system based on B/S mode. This system is composed by S3C2416 microprocessor and other peripheral equipments. Based on embedded Linux operating system, this system is access to the Internet by Web technology, remote users can access it by using a browser. Firstly, the system captures video images using V4L2 capture technology from Logitech C270 webcam. Secondly, the captured images are directly compressed into JPEG format in memory. Finally, the data is transmitted wirelessly to the Internet via the wireless module RT5370. By transplanting MJPG-streamer and Thttpd, the system achieves the capture and format conversion of video images, and can remotely access to the server. By adding the applet in HTML program, the browser can automatically load and display the video images. In the Internet environment, users can view real-time video using a browser of mobile phones or other mobile devices.In addition, a moving object detection algorithm based on the background subtraction is used for the monitoring system, and it is accomplished by applying Open CV. When a object enters the monitoring area, the system will automatically capture a image and send a warning email to host. With this video monitoring system based on embedded Web technology, people are able to take into account work and family to a certain extent. So it will have a certain practical value and significance.
