Hi Chris,
The email has some ambiguity so apologies.
Blue Iris was Sentry AI's first integration and our Blue Iris customers were our very first customers. We are very grateful and have no intentions of changing/or altering the policy for those customers (current subscription, add-ons, multi-year subscriptions etc). Whatever was purchased will be honored. After May 1st, we will no longer be offering 10 cameras for $50 per year, i.e. new customers will have a new offering. Has ZERO effect on current customers.
In addition, we will be releasing new features such as vehicle detection and person recognition (facial id). These features will also come with new pricing.
Hope that provides better clarity.
