* This Surveillance Storage Capacity Estimator tool is provided for illustrative purposes only. Total Storage Capacity is calculated based on parameters selected in the tool, typical compression ratios determined solely by WD for MJPEG, H.264, and H.265 video formats and color depth based on 30 bits for 4K resolution 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.
