A speed camera to catch speeders on the highway.
Dude, that scamera nailed me going 100 MPH.
A traffic camera, in the eyes of those who hate them and think the state is out to make money off of them.
"Scamera" is a portmanteau of SCAM and CAMera. (It could also be a portmanteau of Speed and CAMERA).
I got slapped by a SCAMERA!!!
