Curious how you claim zero false negatives though (as in missing a person it should have detected), unless you’re reviewing all the data or have another system hooked up to it verifying? Or perhaps you simply mean to imply nothing bad has happened due to a missed detection?
In curious hope it did during Halloween with all the costumes? Are you able to have it pre alert you that kids are coming to the door?
The “yard” part, I review every week. Here, of course, I have no data to compare it to, so I cannot say if it’s missing anything.
So yes, I’m certain it misses nothing that’s important to me - is there someone at my door and who is it.
It works well with other costumes like Trail Running and Hiking gear. It also works in the dark (IR camera) and in crazy hard tests like just peeking around the corner with only part of the face visible.
