Right Sized Video Storage
Estimate how much video storage your system needs, from camera-mounted microSD cards to multi-camera NVRs. Adjust bitrate, recording time, retention, resolution and compression to build a practical storage estimate.
Your Storage Estimate

- Pro / Max Endurance
Why? Frequent video recording continuously writes and rewrites the card. Endurance-rated media is designed for substantially heavier write workloads than general-purpose storage.
Choose Storage by Application
STORAGE THAT MATCHES YOUR RESULT
Use your storage estimate above as the minimum capacity
target. For frequent or continuous recording, choose endurance-rated media at
or above the recommended size so the card or drive can handle repeated video
writes.
Edge MicroSD
Choose high-endurance or max-endurance microSD cards for cameras recording locally at the edge.
Why Endurance Matters
Security cameras continuously write, erase and rewrite data. Ordinary memory cards are not designed for that workload, especially with continuous recording.

NVR Hard Drives
Choose surveillance-rated hard drives designed for
continuous recording and multiple video streams.

SSD Drives
Use SSD storage where speed, compact size, or silent
operation matters, while still checking write endurance.

How Storage is Calculated
Storage is estimated from bitrate × recording time × number
of cameras × retention, with capacity rounded up for practical headroom.

Frequently Asked Questions
How long will a card record? The answer depends on bitrate,
resolution, frame rate, compression, recording schedule and retention settings.
