That's impressive chaining BI to Amazon Rekognition on your own. We will work with BI to associate alerts to Sentry triggers as a customer configurable setting in a near-term release. Afterwards, would love to hear your feedback on our image processing. We believe we are better than Rekognition but always receptive to independent feedback.

I hope I didn't mislead you. The only thing BI has to do with me using Rekognition is to provide the external trigger through a script when motion occurs which I'm sure is what you meant by "chaining". Just wanted to make it clear that it's not direct integration at all.
