How to use Security Camera Storage Calculator
- Estimate daily recorded GB from actual recorder statistics.
- Set retention, compression, and redundant-copy assumptions.
- Check forecast storage against recorder throughput and retrieval needs.
Calculator guide
Understanding Security Camera Storage Calculator
Camera storage is governed by aggregate recording volume, retention, compression, copies, and growth in camera count or bitrate.
Calculation method
How the calculation works
Translate daily security-camera storage creation into retained raw volume, apply compression and replica count, project monthly growth, and reconcile current and forecast storage capacity and run-rate cost. Daily recorded volume times retention days gives raw video history; compression and replicas determine stored capacity.

The diagram separates camera sources, daily recording, retention window, copies, and forecast capacity.
Worked situations
Practical examples
- Motion recording reduces daily volume only when the observed activity rate supports it.
- Adding cameras can be represented through monthly volume growth.
- A redundant recorder or cloud copy increases stored copies.
Better inputs
Useful tips
- Measure daytime and nighttime bitrate.
- Include audio, metadata, and event clips when stored separately.
- Confirm legal retention and privacy requirements.
Before relying on the result
Limitations and common mistakes
- The model does not calculate codec bitrate from resolution and frame rate.
- One blended storage rate is used.
- Write throughput and simultaneous playback limits require separate checks.
Reference
Key terms
- Recorded volume
- Video and associated data written each day.
- Retention
- Days of footage preserved before overwrite or deletion.
- Replica
- Additional stored copy for resilience or cloud access.
Important note
Calculated from the entered technical values using the displayed model. Validate topology, workloads, capacity, security, redundancy, and observed performance before implementation.
Frequently asked questions
Can I calculate GB/day from camera bitrate?
This page expects daily GB; use a bitrate calculator first if needed.
Does motion detection change retention?
It changes daily volume, while retention remains the policy window.
Should cloud backup count as another copy?
Yes, when it stores the same retained footage separately.
