| Abstract: | Closed circuit television monitor system is widely applied in living and working. But in some environments, closed circuit television monitor system can not be realized due to the limitation of the cost and landform. The development of wireless web products and the maturation of video compression standard provide a good solution for this condition. The paper dissertates the theory and feature of two kinds of typical spread spectrum technology from the point of project. According to the applied environments, the article offers the concrete methods for selection of frequency band, adoption of spread spectrum technology, adjustment and selection of antenna. |
