Video Security Planning Tools & Storage Calculator
Use the free storage calculator and project planner without signing in. Review inputs, results and worked examples for protected CCTV and LPR design studios.
Storage & NVR Calculator
Estimate recording storage and stream bandwidth.
Free calculator. No sign-in required.
- Inputs
- Camera count, recording resolution, frame rate, compression, schedule and retention. Measured bitrate is optional.
- Results
- Continuous/motion video data, usable capacity including reserve, and recording-stream bitrate.
Worked example
8 × 4 Mbit/s × 3,600 s/h × 24 h/day × 30 days ÷ (8 × 1,000,000) = 10.368 TB of video (decimal).
Continuous recording at a constant average bitrate; decimal TB. Add capacity for filesystem overhead, redundancy and operating reserve. This is not a disk or recorder recommendation.
CCTV System Design Studio
Plan scene coverage and evidence detail.
The full studio requires an approved partner account.
- Inputs
- Scene width, distance, image resolution and required pixel density.
- Results
- Field of view, planning geometry, camera positions and bill of materials.
Worked example
An image 3840 pixels wide over a 15.36 m scene gives 250 pixels/m.
LPR / ANPR Design Studio
Plan the geometry of license-plate capture.
The full studio requires an approved partner account.
- Inputs
- Plate width, lane coverage, image resolution, distance and mounting angle.
- Results
- Plate pixel width and checks for lens, mounting and exposure.
Worked example
For a 1920-pixel image spanning 4 m, a 0.52 m plate occupies about 250 pixels when viewed front-on.
1920 × 0.52 ÷ 4 = 249.6 pixels. The plate size is an example, not a country specification. Oblique angles reduce projected width; recognition must be validated for the selected model, firmware, plate type, speed and light.
