The design of a wireless transmission of digital video monitoring system for vehicles entering and leaving the harbor

A wireless transmission of digital video monitoring system for vehicles entering and leaving the harbor which based on serial camera and Data Transmission Radio (DTR) is designed, the system´s basic components and related principles of work are discussed in the paper. The video capture technology and the wireless data transmission technology applied in this system are analyzed with emphasis. A kind of serial camera with the image compression function is used in the system, which enhances the image transmission efficiency. Data transfer is completed by the DTR which could pass the image information of all vehicles according to a certain time sequence in real time and quickly.
