Storage Calculator

A simple Calculator to help you estimate how much storage you need. 
Keep in mind, storage depends on many factors such as the amount of movement in your property that cannot be accounted for. Use this as a guide to help you get as close as possible to the results you desire. We recommend if possible, always enabling h265+ on all your cameras for improved storage.

H.264 vs H.265 Compression Guide

Choose the best video compression format for your surveillance system based on your hardware and storage needs.

Feature H.264 (AVC) H.265 (HEVC)
Compression Good Excellent (up to 50% savings)
CPU Usage Lower Higher
Compatibility Very High (older devices) Modern systems only
Storage Use More Less
Ideal For Older DVRs, legacy systems High-res cams (4K+), modern NVRs

💡 Quick Recommendations

  • Use H.264 if you're on older hardware or need maximum compatibility.
  • Use H.265 for high-resolution setups or to save storage and bandwidth.
  • Enable H.265+ (or H.264+) if your device supports smart codec – ideal for 24/7 motion detection recordings.
