Abstract
Now, applications from China's wireless monitoring system, high-definition wireless video surveillance system virtually is non-existent. With all the wireless monitoring system, the system transfers the image quality is often not very good.The "mosaic" images from time to time occur and instability. Followed by the poor image definition, often only look at images of human forms and movements, but can not see the face of such people. Therefore, the development of high-definition wireless video surveillance system is very necessary!
The system is easy to complete a design aimed at the local wireless network monitoring systems, and hope that the system can achieve a standard definition of data in real time, high-speed transmission. And the graduation project is the main content of the completion of the hardware design of the receiving unit. Requirements and systems should be designed to match the overall design and function compatible with its software.
