Talk about the wonders of technology.

A two-minute video has surfaced showing a young couple in a cinema in Thailand carrying out extra-curricular activities -- when they thought they were ensconced in privacy because they paid for a pair of seats in a relatively empty theatre.

The footage was apparently shot in a darkened environment, as reported on July 7 by Khaosod, a Thai publication.

Khaosod has taken measures to censor the explicit portions of some of the footage:

Unbeknownst to some, cinemas these days are mostly equipped with cameras in a bid to monitor and deter all kinds of activities.

Are Singapore cinemas monitored by CCTV?

Yes.

MyPaper reported as early as April 2012 that cinemas in Singapore have closed- circuit TV (CCTV) cameras installed.

These included Golden Village, Shaw and Cathay cinema chains.

The reason given back then was that cameras were installed for security reasons, as well as to deter pirates from filming the movie.

But GV did not reveal where exactly in the theatres the cameras were installed, citing security reasons.

A GV spokesman did say that "they are installed for general surveillance and safety purposes".

Other reasons include monitoring the situation in case of emergencies such as fires.

Cathay said it installed cameras at entrances, exits and in projection rooms.

All-seeing cameras then

One supplier of security cameras told the paper then that the model of cameras that cinemas used appeared capable of capturing video footage, and not just stills, and could zoom in and out.

One cinema-goer was quoted as saying: "They can deter people from recording movies and even detect perverts."

The issue of privacy was not broached in the reporting.
