Bottom line, I was sold a camera that had person detection as a feature and now the camera I bought does not. That is called a scam. I feel a class action coming out of this, but I should be able to return my over 2 year old cameras now that they don’t have person detection.
While I understand your frustration, your over 2 year old cameras did not come with Person Detection.
Xnor Person Detection was introduced in July 2019.
Person Detection was introduced in July 2019 and removed in November 2019. If the cams are over 2 years old they were not sold with a promise of Person Detection.
