<human>: Can you succinctly summarize the text in 1-3 sentences?

Ok, first post, possible throwaway.

I know you aren't all lawyers, but....

I have a neighbor who has set up a DIY stop-sign camera at the intersection outside his house.  All of the surveillance equipment is located on his property, but he is taping the public intersection (as well as possibly the private property across the street).

I realize that while driving or in a public space I have no reasonable expectation of privacy from *authorized surveillance*; however, I am not sure what constitutes *authorized*.  I would not feel as violated if it were an official (such as a squad car) stakeout of the intersection, but this guy seems to be taking the law into his own hands.

[I have found an excellent pamphlet on this very subject] but it's **Swiss** and likely not applicable in the US.

What are the community's thoughts on the matter?  Should I change my route to work, confront the guy, call the cops?  I found out this information this morning after I passed through the stop sign (stopping, mind you) and the neighbor ran out to the middle of the street, wildly waving his rake, stopping in front of my vehicle and informing me that his 
>1080p camera just caught you ignoring that stop sign: I haven't given it to the Police yet, but wanted to get everyone to slow down.

There are no signs indicating that this type of surveillance is occurring, either with or without the approval of the local authorities.

/sigh
<bot>: Neighbor installs unmarked, homebrew surveillance system to monitor intersection with supposed frequent stop sign ignorance and possibly more, threatens to submit footage to the police.
