Splitting Crime prevention and prevalence into two sections[edit]

Due to the amount of information now in the Crime Prevention of Prevalence section I propose splitting these into two distinct sections: Crime Prevention and Prevalence. It will make it easier to read. Any thoughts?Infocourse (talk) 22:44, 16 October 2011 (UTC)

Changes to Crime prevention and prevalence Section[edit]

I am proposing to add a few changes to this section. First I would like to add a small notation on the cost-benefit of the installation of CCTV for crime prevention as currently this is missing. Second, I would like to add a counter argument to Public Area CCTV and Crime Prevention: An Updated Systematic Review and Meta-Analysis article to provide a more well rounded view to this section of the article. Infocourse (talk) 22:34, 16 October 2011 (UTC)

Article Title[edit]

I noticed that the term "Video Surveillance" links to the "Closed-Circuit Television" (CCTV)article. Do you agree on having two different articles, one for video surveillance and a separate one for CCTV? Video surveillance is more than a fixed camera like CCTV is. Thoughts? --RPT01 (talk) 16:25, 24 June 2009 (UTC)

I think that having the Video Surveillance article link in here may no longer be appropriate. Times change. While at one time virtually all video surveillance used or was CCTV, that is clearly no longer the case. So I support your idea to reconsider the article title. If something gets going on this later on, someone please invite me back. N2e (talk) 21:03, 6 October 2009 (UTC)
I agree about the split. On U.S. campuses, closed circuit television can refer to the campus-only (often cable) television network consisting of a mix of local productions and entertainment networks like mtvU, Zilo, and the former Burly Bear. 72.244.207.70 (talk) 07:54, 21 November 2009 (UTC)
I support the split: The term closed circuit TV (CCTV) is a tired tern used in the 70's and 80's. Few professionals in the industry refers to the industry as CCTV anymore. The key term is Video Surveillance. Checking the search volume on google for both terns clearly shows video surveillance dominates 4 to 1 over CCTV as the reference used for the technology and the industry.[—Preceding unsigned comment added by Scm research (talkcontribs)
Also supporting the split. Suggestion to change the title to "Video Surveillance" and including a general and modern definition of video surveillance, background, history and technology contributions. All different technologies should be split to their own articles. 195.60.68.148 (talk) 13:26, 11 February 2010 (UTC)

I don't see a reason for a multiway split. Most the article is about security cameras, their technology and politics. That's what should be split off, into Security camera which would mostly be about the use of video for this purpose but would also mention the automatic film cameras that were used in many banks in the 1970s. Old and tired as the term "CCTV" may be it is still a distinctive topic; merely one not dominated anymore by a single application. Jim.henderson (talk) 02:47, 8 March 2010 (UTC)

Instead of splitting, how about renaming it Video surveillance?

We could keep a paragraph talking about the historical use of "closed-circuit television".

Pnm (talk) 02:08, 15 May 2010 (UTC)

I agree with the split. It would make a lot of sense. Maybe CCTV (Surveillance) and CCTV (Television)? Quintusπ talk 01:29, 26 October 2010 (UTC)

Isn't it all television? Jim.henderson (talk) 06:03, 8 December 2010 (UTC)
  • Split declined for now. (Video) surveillance is an aspect of CCTV which is explained in the article. There is no specific section on surveillance in general - the nearest would be Crime prevention and prevalence in the UK. If (when?) a section on surveillance develops to an extent it becomes too large then it can be split out per WP:Summary style. SilkTork *YES! 22:23, 14 March 2011 (UTC)

Hi, guys~ I've been lead here to find some useful guidence about how to understand the architecture and technics of digital surveillance video system with popular IT technologies, and how to build my own one. But I find little I want. The ideas to create a sperated article of surveillance system, I think that may help engineers like me. I suggest that article should have a large part descripting the relationships of those protocols, like H.264, MPEG4, SIP, etc. If I made myself not so confused with those issues, I would pay my contribution within that page, I promise~ --Esmool (talk) 16:30, 16 April 2011 (UTC+8)

CCTV!=Closed-circuit television[edit]

When I enter CCTV it will be redirected here. But CCTV also means China Central Television. --Peterxj108 (talk) 13:34, 8 November 2010 (UTC)

There is a note at the top of the article directing people to CCTV (disambiguation) which lists China Central Television. SilkTork *YES! 22:25, 14 March 2011 (UTC)

Outside the UK[edit]

It mentions New York City but cites a statistic from 1998. Seems a bit out of date to be in an article like this. MDuchek (talk) 16:05, 12 July 2011 (UTC)

I would like to add a section dealing with the history of CCTV in the United States. As of right now there is mostly information only dealing with the United Kingdom. Shannahan15 (talk) 22:14, 17 October 2011 (UTC)

Looking for feedback on a contribution to the "Privacy" section.[edit]

On October 25th, 2011, I contributed to the "Privacy" section of the CCTV Wikipedia article. Two sentences had been posted in the second paragraph, the first of which brought up two points: 1) Positive views of CCTV argue that the cameras do not violate people's privacy, and 2) In public space, a person's right to privacy "can reasonably be weighed against the intended benefits of surveillance". The first point was responded to in the sentence that followed, but the second point was not addressed, so I contributed a scholarly response with the hope of making this part of the Privacy section more balanced, neutral and comprehensive. Any thoughts? I'd love to hear some feedback from contributors and administrators on this. W charbonneau (talk) 04:59, 31 October 2011 (UTC)

Privacy[edit]

This section could be improved. In particular, the reference to Katz is specious unless a notifiable source has made it - the Katz ruling was whether a conversation in a phone booth counted as private, and the verdict stressed that the main reason it did was because a closed phone booth gives a reasonable expectation of privacy compared to the street, so how could this be (mis)interpreted as meaning that you have a reasonable expectation of privacy in the street? Moreover, it only stressed his conversation was private, not anything that was clearly visible from outside the phone-booth e.g. his actions and behavior, which is all a CCTV camera would be able to monitor.

The statement about whether US courts have ruled CCTV unconstitutional is completely uncited. I'm removing it. If it is returned with a citation, I will not remove it again. — Preceding unsigned comment added by 124.158.16.33 (talk) 01:26, 23 April 2012 (UTC)

History / first deployment[edit]

This article currently says that the "first CCTV system was installed by Siemens AG at Test Stand VII in Peenemünde, Germany in 1942, for observing the launch of V-2 rockets". However, 1936 Summer Olympics says "To outdo the Los Angeles games of 1932, Germany built a new 100,000-seat track and field stadium, six gymnasiums, and many other smaller arenas. They also installed a closed-circuit television system and radio network that reached 41 countries, with many other forms of expensive high-tech electronic equipment".[1]   — C M B J   11:44, 16 March 2013 (UTC)

  1. ^ Rader, Benjamin G. "American Sports: From the Age of Folk Games to the Age of Televised Sports" --5th Ed.
Perhaps the criteria of "closed" should be adjusted. This instance of military CCTV was very much closed and secret. Olympic TV was the opposite, an open propaganda exercise. Jim.henderson (talk) 13:36, 29 January 2014 (UTC)

What is Closed?[edit]

The "Closed" part should be expanded on IMO. If it's online, but private, is it still Closed? (Is it the same as Private?) There's a paragraph:

In October 2009, an "Internet Eyes" website was announced which would pay members of the public to view CCTV camera images from their homes and report any crimes they witnessed. The site aimed to add "more eyes" to cameras which might be insufficiently monitored. Civil liberties campaigners criticized the idea as "a distasteful and a worrying development".

That doesn't seem to be Closed. There's also a paragraph:

Recently CCTV has been transformed by the shift towards internet-based products and systems, and other technological developments.

Is that still CCTV, or is that what the paragraph is saying: we're shifting from CCTV to ... something else?

Other names[edit]

This is a minor bit of feedback, but should we list other names that are used for CCTV? When I hear the term CCTV, I typically hear it from brits. I think terms like surveillance footage or surveillance videos are used more frequently in the US. I actually had to google the term CCTV a few months back because I didn't know what it was.

Article title (II)[edit]

I'd like to revive this topic (discussed long ago further up under "Article Title"), as this article seems to be mainly or only about "Camera surveillance" (and I believe the name of the article should perhaps be renamed, and a seperate article be created dedicated to CCTV technology). CCTV is a technology of which "camera surveillance" is only one application (using CCTV but also many other technologies nowadays). CCTV technology has much more (older?) applications like (but not limited to) Campus TV; rear-view camera's in vehicles; monitoring of production processes in plants and factories; (door) intercom systems with a camera (sometimes wireless); information screens in airports, hospitals, public buildings; information channels on hotelroom televisions, in many medical procedures and practises and then some. On the Dutch Wikipedia we've now split "Closed-circuit television" and "Camera surveillance" (Dutch: cameratoezicht), but it makes the interwiki links a bit odd/off. Also, the wikidata object for this article has an English description which doesn't really match the content of this article (in my humble opinion). Looking forward to views and opinions on this. Regards, Martix (talk) 13:20, 29 May 2016 (UTC)

I second to revive this discussion and hereby submit a request for renaming this article to

The result of the move request was: Not moved. No consensus supporting the move. (closed by a page mover) (non-admin closure). Anarchyte (work | talk) 11:52, 8 June 2016 (UTC)


Closed-circuit televisionVideo surveillance – Most info in this article seems to revolve around the use of video surveillance in cities. That's what the video surveillance article can thus be about; CCTV is not the correct term here as that's about a closed circuit video system, whereas most cities make the video feeds available via internet (to either police, or other city services or private citizens). The extra CCTV technology info Martix mentions can be put in an other article called say History of CCTV KVDP (talk) 15:25, 31 May 2016 (UTC)

Oppose: CCTV is the WP:COMMONNAME, and also the most accurate one. If there is any content in this article that does not fall under the remit of CCTV then it should be split out. This page should remain at CCTV. Ebonelm (talk) 20:02, 31 May 2016 (UTC)
  • Is there an ENGVAR issue here? —  AjaxSmack  21:45, 31 May 2016 (UTC)
  • If the proposal is that Video surveillance is more common as a name for this topic than Closed-circuit television and this has consensus then happy to support the article move. This may be a simple difference in Engvar. There is already an article on surveillance which covers camera and video sureillance. Splitting this article would create a WP:POVFORK duplicating this article and the surveillance article. Whizz40 (talk) 08:38, 1 June 2016 (UTC)
  • Oppose. May be an ENGVAR issue, as CCTV is certainly still the common term used in the United Kingdom. -- Necrothesp (talk) 15:22, 1 June 2016 (UTC)

The above discussion is preserved as an archive of a requested move. Please do not modify it. Subsequent comments should be made in a new section on this talk page or in a move review. No further edits should be made to this section.
