How it's calculated

Formula

Total BandwidthMbps=Devices×Bitratekbps1000Total\ Bandwidth_{Mbps} = \dfrac{Devices \times Bitrate_{kbps}}{1000}
Devices
— Number of cameras or streaming devices

What is the Network Bandwidth Calculator?

Streaming devices that run continuously (like CCTV cameras) each consume their full bitrate constantly — this calculator sums per-device bitrate to find the total sustained bandwidth a network link or switch needs to handle.

How to use it

  1. 1 Enter the number of devices streaming simultaneously.
  2. 2 Enter the bitrate each device uses.

Worked examples

8 cameras at 2048 Kbps each

About 16.38 Mbps of sustained bandwidth needed.

Limitations

  • •Doesn't account for network overhead (packet headers, retransmissions) — add 10-20% headroom for real-world links.

Frequently asked questions

Should this bandwidth run over Wi-Fi or wired?

For sustained loads like CCTV, wired Ethernet is strongly preferred — Wi-Fi's real-world throughput is inconsistent and shared across all connected devices.
