How much memory does the camera need for a day's work?

At present, the memory used by mainstream cameras on the market is probably:

The code stream of 65438+720P HD network camera is 3Mbps, which takes up about 1.32GB of storage space per hour and 3 1.68GB per day.

The code stream of the 960p HD webcam is 4Mbps, occupying about 1.79 GB of storage space per hour and 42.96GB per day.

The code stream of 1080P high-definition network camera is 5Mbps, occupying about 2.25GB of storage space per hour and 54GB a day.

Extended data:

The storage space calculation method of the network camera depends on whether the resolution of the network camera is 720P or 1080P.

Any formula is: storage space = time x code rate /8 (8 words in a byte).

If the code rate of the camera is 300Kbfs, that is, 300Kb per second, then the video file size of this hour = 3600 (3600 seconds per hour) * 300/8 = 135000 KB, that is, per hour 135M, so it is calculated.

According to experience, the video surveillance of H.264 and D 1 is based on 25 frames per second. Most environments do not exceed 200 meters per hour.
