What is "electric eye"

n. A sensor which measures the intensity of light, often used to start and stop electrical equipment (motorized doors, etc.).

n. a transducer used to detect and measure light and other radiations [syn: photoelectric cell, photoconductive cell, photocell, magic eye]

Electric Eye is a compilation DVD by Judas Priest released in 2003 and certified Platinum by the RIAA. It features music videos, BBC performances, and the first official DVD release of a concert filmed in Dallas, Texas during the 1986 Fuel for Life Tour, previously released as Priest...Live! on VHS and LaserDisc.

An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam. The device does not provide an image; only presence of light is detectable. Visible light may be used, but infrared radiation conceals the operation of the device and typically is used in modern systems. Originally systems used lamps powered by direct current or the power line alternating current frequency, but modern photodetector systems use an infrared light-emitting diode modulated at a few kilohertz, which allows the detector to reject stray light and improves the range, sensitivity and security of the device.

"Electric Eye" is a song by British heavy metal band Judas Priest, from their 1982 album Screaming for Vengeance, and released as a single later that year. It has become a staple at concerts, usually played as the first song.

Benediction and Helloween, amongst many other bands, have covered this song.

Musically, the song is in the key of E minor, and its guitar solo is played by Glenn Tipton.

"Electric Eye" is featured in Grand Theft Auto: Vice City Stories for PSP and PlayStation 2. It is also a playable track in Guitar Hero Encore: Rocks the 80s as a master track, including "The Hellion", and it also appears on Guitar Hero Smash Hits. Additionally, it is available for download on Rock Band, as of 22 April 2009, as part of the entire Screaming for Vengeance album download, or as a single song. It was also featured in the second trailer for the video game Brütal Legend.

This song is referenced in the movie Tenacious D in The Pick of Destiny, in the song "Break in-City (Storm the Gate!)".

"Electric Eye" is an allusion to the book Nineteen Eighty-Four by George Orwell, in the use of the name of the pseudo-omniscient satellite that watches over the community at all times. In this dystopia, the form of government, Ingsoc ( Newspeak for English Socialism), is utterly totalitarian, and if citizens are caught rebelling in any manner, they "disappear". The song has been called "prescient" for its depiction of a modern surveillance state.

The song is usually played right after the album's intro "The Hellion" during live concerts. An exception is during the tour for the album Demolition, in which the band went straight into "Electric Eye" with no intro, which can be heard on their live album Live in London. "The Hellion" was also used for a commercial for the 2011 Honda Odyssey.

The song was played live at the 2011 Revolver Magazine Golden God Awards show by Duff McKagan's Loaded, with vocals by Slipknot and Stone Sour's Corey Taylor and guitar by The Sex Pistols' Steve Jones.

"Electric Eye" was covered by the metalcore band As I Lay Dying from the compilation Decas, and was released as a single. The band made a music video for the song and was first available to stream via Noisecreep on 3 October 2011.

In his 2004 tribute album, Mirada Electrica: Tributo A Judas Priest, Arturo Huizar, a prominent pioneer of Mexican heavy metal, covered the song in Spanish with his band Lvzbel. The tribute album also includes other popular Judas Priest songs translated to Spanish. During live concerts, Huizar often switches between English and Spanish in the chorus.

The song was also covered in 2014 by Lissie and released on an EP album "Cryin' to You" and performs the songs on tour.

Professional wrestler Aja Kong uses the song with 'The Hellion' as her entrance music.

Electric Eye are a psychedelic rock group from Bergen, Norway formed in 2012 by Øystein Braut, Njål Clementsen, Anders Bjelland and Øyvind Hegg-Lunde. After their first single "Tangerine" they released their debut album "Pick-up, Lift-off, Space, Time" in 2013.

Electric Eye is the second studio album by the Christian rock band Prodigal, released in 1984.

The band created promotional music videos for "Scene of the Crime," "Fast Forward" and "Boxes," which were featured on Trinity Broadcasting Network's music video show Real Videos at the time of the album's release.

In a 2009 interview, frontman Loyd Boldman said "we put a "stop-groove" at the end of Side Two that would "catch" the vinyl record and wouldn’t allow it to eject on an automatic turntable. If you picked up the needle and set it down again on the other side of the stop-groove, you’d hear a packet of computer code that could be deciphered by a Commodore 64, the most popular computer of that time. If you used a cassette drive, the Commodore would show you lyrics and graphics and some facts about the album."
