Face/head cover problem

my camera seems to be set to facial recognition only.

ive been noticing with deliveries that when they have masks on, the doorbell camera doesnt start recording.

i went out this morning to move something in my yard and it was raining so i put on a hood - not even covering my face - and it did not record me leaving or coming back in.
this to me seems to be a huge gap in security - if someone were to break in or cause damage i would imaging they would cover their face meaning i wouldnt even have a recording of the event.

it did on a side note, take 8 consecutive vidoes of the handlebars of a bicycle on the porch the first day installed
