CCTV Bandwidth Calculator
Calculate the network bandwidth required for your CCTV system based on the number of cameras and video settings.
Basic Settings
Recommended Average Bitrate
3.0 ~ 5.0 Mbps
H.264 · 1080p · 30 FPS · High
The recommended value is a general estimate. If you know the actual average bitrate from your camera or NVR, entering it manually will be more accurate.
This value is used directly for the bandwidth calculation.
Calculation Result
Recommended Total Bandwidth
76.80Mbps
Recommended Network Link
100 Mbps or higher
76.80 Mbps of actual throughput or more is required.
CCTV Bandwidth Guide
Total network bandwidth is calculated by adding the average video and audio bitrate of each camera and multiplying it by the number of cameras.
H.264/H.265, resolution, FPS, and quality settings are used only as references for choosing an average bitrate.
Actual network usage may vary depending on camera manufacturer, VBR behavior, multi-stream settings, NVR configuration, protocol overhead, and network conditions.
