* This Surveillance Card Capacity and Life Estimator tool is provided for illustrative purposes only. Total expected life of a card and minimum card size needed are 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 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 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. Total accessible capacity on storage devices and total life of storage devices may vary depending on operating environment.
