A better law would simply say video that is viewing your property from the outside cannot be used as evidence or something like that.
I fully agree governments should not be participating and they shouldn't have a secret backdoor. I also agree that you should have the expectation of privacy in your house (hence why I question whether the video ought to be admissible). However, handicapping people's equipment is against even the most basic principle of private property.
Like, if you’re in a public park and someone takes a picture that includes you, generally we say that you consented by being in public. If someone takes a picture of you every morning as you jog by the park because they’re stalking you, we don’t extended “implied consent” to that. If you aim a camera at my house, does that count as implied consent, or is it closer to stalking?
The behaviour must give you good reason to fear for your personal safety and it must have no legitimate purpose
It doesn't apply here.
Believe it or not you have neighbours watching you leave your house every morning. All streets have nosey neighbours.
