CCTV Network Bandwidth Calculator
Work out the network bandwidth your cameras need to the recorder and for remote viewing.
Use the camera datasheet figure; as a starting point, 2MP is around 2-4 Mbps and 4MP around 3-6 Mbps at 15 fps.
Results
Cameras to the recorder: 70.4 Mbps
Remote viewing (site upload needed): 2.2 Mbps
Total: 72.6 Mbps
Share of a 1 Gbps link: 7.3%
The remote viewing figure is the upload speed the site internet connection needs to support.
How it works
Recording bandwidth is the number of cameras x bitrate, plus an allowance for network overhead. Remote viewing adds the number of streams watched at once x their (usually lower) sub-stream bitrate -- that part has to fit within the site's internet upload speed.
