Camera Storage calculation

Hello, dear.
It's nice to meet you in the community.
We're working on getting the right answer for you. Please rest assured that we'll be back with an answer shortly.

Hi, dear!

The storage capacity is calculated based on the bit rate. The formula for calculating the storage capacity is as follows:
1 hour storage capacity of a camera with the bit rate ofn (unit: Mbit/s) = [(n/8) *3600]/1024 GB.

Formula parsing

• n Mbps/8 Conversion unit: n MBPs
  

• n MBPs*3600 Calculate the storage capacity in one hour (unit: MB).
  

• n *3600/1024 The unit is GB.
  

The following provides an example to describe how to calculate the raw capacity required for storing video images. Assume that there are 100 channels of 720p IPC - the storage bit rate is set to 2 Mbit/s and all day recording is required. The storage duration is 30 days.

The calculation process is as follows.

1. Firstly, calculate the raw storage capacity required by a single video everyday:

[2Mb/s*3600s/h*24h]/8 = 21.1GB

2. Calculate the raw storage capacity required by a single video for 30 days.

[2Mb/s*3600s/h*24h]/8*30 = 633GB

3. Finally, calculate the raw storage capacity of 100 channels of videos in 30 days.

[2Mb/s*3600s/h*24h]/8*30*100 = 63300GB/1024 = 61.8T.

Thanks!

Total Storage Capacity is calculated based on parameters selected in the tool, typical compression ratios determined solely by Western Digital for MJPEG, H.264, H.265, and H.265+ video formats in conjunction with video quality and scene activity, and color depth based on 30 bits for 4K resolution and higher and 16 bits for all other resolutions. Storage capacity needs may vary depending on actual number of cameras connected, days of storage required, video format, compression ratio, camera resolution, frames per second, color depth, system capabilities, components, hardware, configurations, settings, and software, and other factors. Any reliance on this tool and its output is at the third party's own risk. As used for storage capacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes. Total accessible capacity on storage devices may vary depending on operating environment.

you can try some online tools to calculate this,

An easier formula is

=(CAM*days*24*3600*2*1.1*1024*1027)/(8*1000*1000*1000*1000)
