n. pl. cam·er·ae (-ə-rē)
A chamber or cavity, such as one of the chambers of the heart or eye.
Being filmed, as in When the talk-show host began, I wasn't sure if we were on camera. This usage dates from the first half of the 1900s, soon after the birth of motion-picture and television filming. The same is true of the antonym off camera, meaning "outside the view of a movie or TV camera," as in Go ahead and scratchwe're off camera now.
