Problems solved by technology

[0018] When the number of front-end encoders is large, if the video is pushed to the center at the same time, it may cause congestion in the center network
And for the recording triggered by the alarm, the pre-alarm recording is also very important. In the prior art, the pre-alarm recording can only be saved by the memory buffer, and the pre-alarm recording storage period is very short, usually on the order of ten seconds
