Overview

The Camera Bandwidth Calculator estimates CCTV network bandwidth usage, recording traffic, storage consumption, and recommended LAN capacity for IP camera deployments. It helps surveillance installers, network engineers, NVR administrators, and CCTV planners calculate how much bandwidth and storage multiple cameras will consume based on resolution, codec, frame rate, bitrate, quantity, and recording duration.

Common Use Cases

How to Use

1
Add one or more camera profiles.
2
Select the camera resolution such as 720p, 1080p, 4MP, or 4K.
3
Choose the video codec such as H.264 or H.265.
4
Enter the camera frame rate (FPS).
5
Input the estimated camera bitrate in Mbps.
6
Specify the number of cameras using the same configuration.
7
Set the daily recording duration in hours.
8
Review the estimated per-camera bandwidth, total traffic usage, daily storage requirements, and monthly storage estimation.

Example Scenario

Office CCTV Deployment

A small office installs multiple 1080p H.265 cameras recording continuously at 15 FPS. The calculator estimates total network traffic, monthly storage requirements, and whether a 100 Mbps or 1 Gbps LAN is recommended for stable operation.

Technical Notes

Bandwidth usage is primarily calculated using configured camera bitrate, adjusted by resolution, codec efficiency, frame rate, and total camera quantity.

H.265 typically provides lower bandwidth and storage usage compared to H.264 while maintaining similar visual quality.

Higher FPS values increase bandwidth and storage consumption because more video frames are transmitted and recorded each second.

Monthly storage estimation is based on total recording traffic, recording hours per day, and continuous recording assumptions.

Recommended LAN speed is estimated based on total aggregated camera bandwidth across the surveillance network.

Storage calculations assume continuous recording and do not account for motion-triggered recording optimization.

Common Mistakes

Frequently Asked Questions

Bitrate, resolution, codec type, frame rate, motion complexity, and the total number of cameras significantly affect bandwidth consumption.

H.265 is a newer video compression codec that reduces bandwidth and storage requirements more efficiently than H.264.

Yes. Higher frame rates generate more video data, increasing both bandwidth and storage consumption.

No. The estimator assumes continuous recording and actual storage usage may be lower when motion-based recording is enabled.

1 Gbps LAN is generally recommended when total aggregated camera bandwidth approaches or exceeds Fast Ethernet capacity.
