Molka is the Korean term for hidden cameras or miniature spy cameras secretly and illegally installed, often in order to capture voyeuristic images and videos. Molka is an abbreviation of mollae-kamera (몰래카메라), which means "sneaky camera". The expression originated from the homonymous title of a Korean prank TV show, which existed from March 1991 to November 1992. This makes the term denote prank and spy camera at the same time.
