I am installing an IP camera system and want to know how to calculate much upload speed is necessary to view the cameras remotely.

The cameras use H.264 compression.

Thanks

Not enough data to calculate it for you.

Need camera resolution, FPS, number of cameras.

Use this link and add the numbers: https://www.cctvcalculator.net/

Dont take offense but I dont think the calculator is accurate.

I have some SV3C IP Cameras (SV-B01POE-1080P) 1920 X 1080=2.1MP

I used 3 bandwidth calculators to try and determine my bandwidth needs. On all calculators I entered 1920 X 1080p resolutions (or as close as the calculator would get)
H.264 compression
30 fps
medium video quality
1 camera

Your calculator said I need 0.4mbps for local bandwidth (see attachment cctv calculator)
Stardot said I need 8.2mbps (see attachment stardot calculator)
Supercircuits said I need 6.27mbps (see attachment supercircuits calculator)

How do you explain this?

Interesting.

If CCtvcalculator is that inaccurate, I think I'll throw it to the curb and start using Stardot and Supercircuit.

Hi,

local bandwidth is in MB/s (megabytes per second), not in Mbps. The calculation says 3 Mbps. Local bandwidth is the value for a disk controller design.

See the real data in attachment.

BTW If there is no profile definition behind H.264, it usually means H.264 Base.
