1. What is NVR Storage Calculation?

NVR (Network Video Recorder) storage calculation estimates the required storage capacity for video surveillance systems based on camera parameters, recording duration, and compression efficiency.

2. How Does the Calculator Work?

The calculator uses the NVR storage formula:

\[ \text{NVR Storage (TB)} = \frac{\text{Cameras} \times \text{Resolution} \times \text{FPS} \times \text{Hours} \times \text{Days}}{\text{Compression Ratio}} \]

Where:

\( \text{Cameras} \) — Number of cameras
\( \text{Resolution} \) — Video resolution in pixels
\( \text{FPS} \) — Frames per second
\( \text{Hours} \) — Recording hours per day
\( \text{Days} \) — Number of days to store recordings
\( \text{Compression Ratio} \) — Compression efficiency factor

Explanation: The formula calculates raw data volume and adjusts for compression to determine actual storage needs.

3. Importance of NVR Storage Planning

Details: Proper storage planning ensures sufficient capacity for desired retention periods, prevents data loss, and optimizes system performance and costs.

4. Using the Calculator

Tips: Enter the number of cameras, resolution in pixels, frames per second, daily recording hours, desired storage days, and compression ratio. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical compression ratio for video surveillance?
A: Modern codecs like H.265 typically achieve compression ratios of 50:1 to 100:1, depending on video content and quality settings.

Q2: How does resolution affect storage requirements?
A: Higher resolutions (4K vs 1080p) significantly increase storage needs. 4K requires approximately 4x more storage than 1080p at the same compression.

Q3: What factors influence compression ratio?
A: Video content complexity, motion levels, codec efficiency, and quality settings all affect compression ratios.

Q4: Should I include a safety margin?
A: Yes, it's recommended to add 20-30% extra capacity for unexpected requirements and system overhead.

Q5: How often should I recalculate storage needs?
A: Recalculate when adding cameras, changing resolutions, extending retention periods, or updating compression technology.
