How to plan network broadband for network video surveillance system?

The network video surveillance system network can be divided into three parts according to the front end, central service platform and client:

1. Front-end bandwidth: The required bandwidth is estimated; if a front-end has only one video server to transmit a 25-frame / second DIF-image, the required bandwidth is 384kbps.

2. Platform: The central service platform broadband mainly has two parts, one is the video stream uploaded by the front-end device; the other is the video stream distributed by the central service platform to the client.

The broadband planning of the central service platform operated by the public network can be planned based on the simultaneous monitoring and concurrent scale of 50% of the full-load front-end video of a platform.

3. Client: Time needs to be determined by monitoring the number of video channels. Since the bandwidth required for each channel of video can be estimated, if a video server transmits a CIP image (still image) of 25 frames per second, the required bandwidth is about 384kbps (if the general motion of the image is considered, the code stream may be Increased to 512kbps). If the number of channels monitored simultaneously is n, the broadband plan on the client side is as follows: n * 512 (kbps).
