With the development of video surveillance from SD to HD, the requirements for target monitoring are more clear and effective, and the requirements for video playback pay more attention to details are getting higher and higher. therefore, the requirements for video monitoring and storage are getting higher and higher.Today, the editor will tell you about the algorithm of video surveillance storage space.

To calculate the size of video surveillance storage, you must first figure out several professional words:

1. Bit rate.
The bit rate is the number of bits (bit) transmitted per second. The unit is bps (BitPerSecond). The higher the bit rate, the more data is transmitted. The bit rate indicates how many bits are needed to represent the encoded audio and video data per second. The relationship between the bit rate and audio and video compression is simply that the higher the bit rate, the better the quality of the audio and video. But the larger the encoded file is; if the bit rate is less, the opposite is true.

two。. Code stream.
Bit stream (DataRate) refers to the data flow used by video files per unit time, also known as bit rate, which is the most important part of picture quality control in video coding. At the same resolution, the larger the code stream of the video file is, the smaller the compression ratio is, and the higher the picture quality is.

After figuring out these two nouns, it's easy to figure out the storage space you need.
