16 hikon 4 million cameras. How big a hard disk does it take to store 15 days?

16 haikang 4 million camera needs 1T memory for at least 15 days, because the specific calculation formula of formula code stream is as follows: 3600X24÷8÷ 1024= recording capacity 1 day, so a 4 million pixel camera with H.264 code needs. Generally speaking, the coding of H.265 camera is half that of H264 camera, the common 200W pixel camera code stream is 2M, and the 400W camera code stream is 3M. The calculation method is the same as H264, and the storage space of a 400W pixel camera is about 30G a day.

The storage capacity of H.264 coded cameras is generally 4 million pixels. The code stream of H.264 coded camera is 2M, the code stream of 4 megapixel camera is 4M, and the code stream of 4 megapixel camera is 6M.

Therefore, counting sixteen Haikang 4 million cameras and storing them for fifteen days, you need to add 16 cameras with 400W on the basis of 42. 19G per day, and multiply them by sixteen days, so at least 1T hard disk is needed to load video data.
