Huh. Not OP, but if the view is constant, I would be very pissed off. If I walk naked out my front door right now, chances are low anyone will see me (quiet neighborhood, it's past midnight), but if OP does it, boom, there s/he is on camera.
And the camera owner can extrapolate when OP/their family members are home or not, when people visit, etc, etc. Could that not be considered surveillance?
The law has not defined it as such. In reality, we absolutely expect our neighbors not to film our front doors 24/7 and give police access to the feed. The law is outdated and ought to be updated to protect against new abuses.
Clearly some forms of observation are abuse, while others aren't. If I repeatedly hide inside the bushes right outside your land and look into your house, I'm merely observing. I'm still a stalker.
If I set up a camera to do the same, why is that better? People are constantly recording their neighbors' comings and goings, their visitors and associations, and sending that data to a bureaucratic megacorp that actively cozies up to law enforcement. "Observation of public space" is reductive, that's a cyberpunk nightmare. It's poisonous to free society.
