Makes perfect sense.
Ignore government satellites that can read your license plate from space, the cell phone which broadcasts your location to cell terminals and GPS and sends Metadata to the NSA, EZPass transponders that record the date and time you pass anyplace that has a receiver, web browsers that report your personal data to any website you visit, and debit and credit cards that give your personal data to every store you visit, and all the private and government security cameras you pass every day (some of which may be fixed on your property).
Instead, worry about an overgrown toy that has a maximum range of a mile or so, has a very limited field of view and no focus capability, and probably doesn't have any live feed.
You'd better get radar or a jammer because they are small, unobtrusive and usually sky-colored so if someone really wants to see something on your property, they're going to do it at dawn, out of the sun, or at least when no one is in view. In other words, your search for the guilty will likely punish the innocent.
