Here in the UK, you are only allowed to record security footage of your own property. If your camera also captures activity from outside your boundaries (and potentially invade people’s privacy) you then become subject to certain recording and data processing laws.
How about a software solution to black out that which you don’t want to record?
You’d setup your camera, point it at what you want to record, but be able to ‘drag in’ black borders to not record footage that’s not on your property.
Just a suggestion
