What are the legal implications of a house owner putting a camera on their house which points at a path with an easement on it, such that someone else has a right of way on that path? I.e. it's not a public right of way and nor is it completely private property.
The aim is for the owner of the house to have evidence if the person with the easement does anything to the owner's property, but not at the expense of incriminating themselves if this is not technically legal.
This is in England.
