* When referring to drive capacity, one gigabyte, or GB, equals one billion bytes; and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage. Quantitative usage examples for various applications are for illustrative purposes. Actual quantities will vary based on various factors, including file size, file format, features, and application software. Actual data rates may vary depending on operating environment and other factors.


Storage Calculator FAQ 

  • What are several factors that influence video storage requirements for security systems?

    1. Number of Cameras: More cameras mean more footage to store.
    2. Resolution: Higher resolution (e.g., 4K) produces larger files compared to lower resolutions (e.g., 1080p).
    3. Frame Rate: Higher frame rates (measured in frames per second) result in smoother video but require more storage.
    4. Compression Technology: Modern compression methods like H.264 or H.265 can significantly reduce file sizes without compromising quality.
    5. Recording Duration: The length of time you need to store footage impacts storage needs. Businesses often retain video for 30 to 90 days.
    6. Recording Mode: Continuous recording uses more storage than motion-triggered recording.
    7. Scene Complexity: More complex scenes with lots of movement or detail require more storage.
  • How do I calculate storage for my CCTV system?

    By inputting the above parameters, the calculator estimates the file size by multiplying the bitrate by the duration of the video and adjusting based on resolution, frame rate, and compression. This helps plan storage needs, especially when working with large footage or high-definition content. 
  • Why is video storage important?

    Choosing the right video storage solution is critical because it affects everything from data security and compliance to cost efficiency and performance. It ensures that your video content is stored securely, remains accessible, and can scale with your growing needs, all while balancing costs and providing the necessary flexibility for your CCTV solution.
