What is obvious- the camera must have AI to send the notifications ONLY when a person is detected, and Tapo fortunatelly has it- which is the most important part of this system.

Hpwever AI should be still being improved.

Motion detection is, in most cases, pointless, because, specially in the night, there are some many insects, birds that, alarms are trigeering very often and then there is no sense to have this function enabled. 

However it would be good (as additional, separate option) to detect cars. This would be great.
