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.

💡 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.
