Sub-minute streams with AWS Rekognition video streaming?

Question

I'm trying to determine whether it is feasible from a cost perspective to use AWS Rekognition video streaming for short, scheduled streams on a camera network.

I understand that they bill $0.12/min for the service, however the docs are not clear if this is rounded to the nearest minutes per streaming invocation or at the end of the month.

This could result in a VERY drastic change in price when you have 1000s of cameras...

For example, if you stream 30 seconds per day for a month, are you billed for 30 minutes or 15 minutes?

Answer 1

15 mins.

From Rekognition price calculation page :

Usage charges are applied monthly and are pro-rated for partial minutes.
