Embedded Remote Video Surveillance System Based on ARM

Abstract

In this study, an embedded remote video surveillance system based on ARM was build. The hardware system is composed of ARM S3C2440 processor, OV9650 CMOS camera, and mobile phone; and the software platform includes three modules-video capture, video processing, and video transmission. Moreover, an improved moving target detection algorithm was proposed, which combines real-time background updating and three frame differencing to reduce the impact from the gradient and emergency in ambient light when long-term monitoring. The test results showed that, when someone appears in the monitoring scene, the system will send the relevant video information to the user's mobile phone via e-mail, that is, an alarm is sent to the user to complete remote video surveillance. In addition, it can adapt to the changes in ambient light when long-term monitoring and also has a good resistance to the sudden appearance of highlight, having good security and stability.
