Legally, there's a debate to be had.
A telescope on a hill that can see everything within a 12sq mi circle Vs a "google maps" type 360 panorama lens on the same hill.
Live only versus 24/7 recording, filtered (only pointed at one house of interest / only logging specific devices / only logging a network of devices that interact with devices of interest)
The question re: "targeted" goes to whether it's opened ended recording of everything, or filtered and targeted sifting out of warranted subjects.
