Right now, if Sentry is checked, all prior triggers that you setup in Blue Iris will first define the motion trigger, so in your case, the zones configuration will first generate the trigger to then send Sentry an image to detect humans. The image sent to Sentry is defined by the MAKE time. We then do the evaluation right now on the whole image. For future releases, we are considering to focus the Sentry AI analysis in the Areas of Interest as defined in BI via zones & hotspots.Forgive me if this was asked and answered already, I didn't find it. In the make time frame(s) that are analyzed by sentry, are the area(s) that are not included in motion zones also analyzed? For example if a front yard has zone A green out to the curb and stops, and a cat, squirrel, shadow etc trips motion in the green area of zone A but a person is mowing their lawn across the street will they be excluded since they are not in a defined motion zone or will that count as a valid alert since a human is in the camera frame? Same question on vehicles, once vehicle detection is implemented. Very happy so far with sentry at my house, but before deploying it for a customer location I had these questions.
So to answer your question, Sentry AI would currently send the alert of the person mowing their lawn. While speaking with customers, I have found that the purpose for creating zones is to reduce false alerts and identify human motion. If that is the case, then perhaps turning off zones and just using Sentry AI for human detection will suffice.
If the zones are to define an Area of Interest (AOI) for other purposes, leave them in place. And in a future release, Sentry AI will take advantage of the AOI to enhance the alert.
