Video surveillance becomes far-reaching thanks to the Internet.The IP camera having both photography and video output functions becomes the primary component in network video surveillance; the bandwidth of the network passageway is fixed but the traffic is changing.In the event of network jam, there must be ways to avoid missing surveillance screen or lag.Therefore, this study proposes a practical approach to make H.264 video encoder dynamically adjust the compression parameters, such as the size of the quantization value, the video frame resolution, and the number of frames generated in each second and more, through a traffic control program to produce adequate video traffic.By doing so, even in the event of insufficient bandwidth at the user-end, the packet dropping and delaying will be avoided and video frames are able to be transmitted to the user in time.
