What
When a person is detected, cover the area of the bounding box
with an opaque (black) rectangle.
Delete detection information to prevent leaking to notifications.
Why
Software should do respect privacy by default.
The intended users of this software, farmers,
often have visitors or workers at their farm.
For such cases, "at-home" privacy rules no longer apply (in Norway).
If their visitors' / workers' personally identifiable information
were to be processed, stored and acted upon by this system,
the farmer would essentially have to fulfill duties as
a PII data processor.
Surveilling people definitely isn't an intended use case
for this software, so its capability as such may as well be crippled
in the name of easing privacy compliance burden for other use cases.
