Maybe not under that term, but for example, almost the only place an American's 4th Amendment protections against search and seizure apply is in their home. Law enforcement can search their garbage at the curb, monitor their [edit: public] movements via camera and license plate monitoring, etc., look them up online, all without warrants [*]. They can't do that in someone's home.
[*] I'm pretty sure no warrant is required to search curbside trash or do most online research.

It's hard to set up video surveillance in your home without inadvertently providing much of the surveillance data the law enforcement officers were after, especially for non-technical people.
