Condensed CCTV

Video analytics is the thing right now. With so much video information and the limits of human operators, what to do with all that footage? There are numerous answers mostly involving forms of algorithmic movement recognition. From the masses of press releases that come my way every day, I notice one Israeli company (Israel being one of the world leaders in security technology), BriefCam, is marketing a new automated system that not only recognises objects of interest but then condenses hours of video which feature the object of interest into a matter of minutes featuring all the salient points from the whole time, at once. Or according to their own website:

“BriefCam VS Online receives real-time feed from the DVR/NVR and processes data to produce a database that can be called on to create a video summary presentation, on demand.”

I’ve seen the technology at work, but one thing starts to concern me imediately is what is lost by way of this combined footage. Check the video here for example.

The blurb claims that it is ‘easy’ for operators to see something unexpected, yet this is not a ‘real’ image, or in fact it is a hyperreal image, multiple images partly overlaid on what is assumed to be a standardized background. Of course, given the original footage remains available contextual evidence can be sought. However, I do wonder what kind of decisions will result from fast-moving combined footage pre-selected to present to a human viewer… and of course, what exactly it is that the system is programed to recognise and how. It seems that operators of video surveillance systems will increasingly be watching is not reality, but combined, edited highlights, a part-simulated recreation. Jean Baudrillard would be having a quiet chuckle if he could see this…

Campaigners uncover UK local government spending on CCTV

Using Freedom of Information requests, Big Brother Watch in the UK has managed to get hold of figures from many British local governments on how much they spend on CCTV surveillance systems.

According to the Press Association, the annual spend by 336 local councils on the installation and operation of CCTV cameras over a three year-period from 2007/08 and 2009/10 totalled £314,835,170.39 (around $400M US). That’s a large amount of money in an ‘age of austerity’… however it is still not complete as there are another 80 local governments who did not respond to the requests. Interestingly there were still some local governments, albeit only 15, who still did not operate public-area CCTV. That’s not to say that the local police forces in those areas did not, however. There are some cities in Britain, the exception rather than the rule, like Newcastle for instance, where police own and operate public CCTV cameras. I am not sure if these are the types of councils making the claims, and I will have to look at all the figures in greater detail.

The top ten spenders on CCTV over the three years were listed as:

  1. the city of Birmingham, Britain’s second-largest city, and controversial for its special scheme targeted at ‘Muslim’ areas, but also with a massively regenerated and semi-privatised city-centre. £10,476,874.00
  2. Sandwell metropolitan borough, a large urban area to the north-west of Birmingham £5,355,744.00
  3. the city of Leeds, in Yorkshire, whose downtown district is the epitome of the characterless, over-regenerated urban centre. £3,839,675.00,
  4. the city of Edinburgh, capital of Scotland, a wannabe global city, and former G8 meeting host, £3,600,560.00
  5. the borough of Hounslow, on the edge of urban and suburban west London, £3,573,186.45
  6. the borough of Lambeth, a diverse south London district, £3,431,301.00
  7. the city of Manchester, one of the cities we studied in our book on urban resilience, which put a huge amount in to CCTV in the downtown core the wake of a provisional IRA bombing, which has now also been gentrified out of recognition – it also has a signficant suburban gang problem, £3,347,310.00
  8. the borough of Enfield, a leafy north-east London suburb, £3,141,295.00
  9. the borough of Barnet, also in north London, £3,119,020.00
  10. the borough of Barking and Dagenham, in east London, on the borders with Essex, and another area of high racial tensions stoked by a strong local British National Party, £3,090,000.00.

Half of the top ten are London boroughs, outside of the centre of London, showing that CCTV is still diffusing outwards from the heavily surveilled core around the financial centre of the City of London and the government district of Westminster. Not surprisingly, the diffusion is also continuing primarily to the major urban centres beyond London, and the case of Sandwell perhaps shows that the greater Birmingham area is going through a similar process seen in London. In any case, public area video surveillance is not going away in the UK any time soon, and the new government will have to, at some time, demonstrate what it actually meant by introducing greater regulation of CCTV.

Manchester Surveillance Blimp Axed

The axed Manchester Police drone (Guardian)

Police in Manchester, UK, have axed a tethered surveillance balloon that cost them 80,000 GBP (around $130,000 US). The supposedly covert balloon – if a large white blimp with ‘POLICE’ written on the side in big blue letters can be called ‘covert’ – had been intended to be used for monitoring of public order at large-scale events. However it was a victim of a more conventional Manchester problem – bad weather. Apparently it did not function very well in wet and windy weather. One would have thought that this might have occurred to the police of a notoriously wet and windy town…

This might seem like a victory for anti-surveillance forces, but of course, this will only increase the pressure for more versatile and weather-proof aerial surveillance, i.e. the micro-UAVs (or camera drones) that several other forces have already purchased, not to mention the more expensive powered high-level surveillance airships of the kind specified in the secret South-Coast Partnership report on drone surveillance.

Problems with Crowdsourcing Surveillance

Bruce Schneier has a nice little piece which is saying similar things to what I’ve been saying over the last couple of years on the subject of ‘crowdsourcing’ or opening closed-circuits of surveillance. He critiques the Internet Eyes scheme and Texas Border Watch and others. This is also the subject of the paper, ‘Opening Surveillance?’ that Aaron Martin of LSE and I presented at the S&S conference in London in April, and which will hopefully be coming out in the journal’s conference special early next year…

Spying on Your Neighbours

One of the characteristics one would expect in a ‘surveillance society’ is that surveillance would become seen as a more ‘normal’ reaction to problems at all levels of society. So we start to see instructive stories about surveillance in all kinds of unexpected places. The ‘Home and Garden’ section of the Seattle Times newspaper carries a very interesting report this week on the use of relatively low-cost surveillance systems (some involving digital movement detection) used by ordinary middle-class homeowners to monitor their property and more specifically to catch their neighbours doing very unneighbourly things, such as tossing dog faeces into their gardens or trying to peek in through their windows.

In most of these cases, it seems the surveillance is primarily about defending property and based around specific observed anti-social behaviours. So, is this just a question of the legitimate defence of property rights and privacy (the legal view) or is this any kind of a social problem? I think it is certainly more complicated than just being a question of individuals empowering themselves with technology to do the right thing.

There is a big unvoiced problem behind all of this which is the decline of civility, neighbourliness and trust. It seems that most of the problems are interpersonal ones and would be ideally best resolved not through the secret gathering of information to inform a police investigation, public prosecution or private legal action, but through communication with the neighbours concerned. Richard Sennett, Jane Jacobs and many others have observed that we live increasingly in a ‘society of strangers’. The turn to surveillance not as a last resort but as a ‘natural’ first option, would seem to me not only a recognition of this, but a contribution to the wider problem. We don’t trust our neighbours so we watch them. But in watching them we diminish any remaining trust we had in them, and certainly they lose any trust they had in us.

This adds up. It is social not just interpersonal. It means people accept the diminution of general rights of privacy in public spaces and justifies the intrusion of all kinds of agencies into the lives of individuals and groups. This is only encouraged by government campaigns to watch out for suspicious activity, corporate pleas to all of us to be permanently on guard against ‘identity thieves’, ‘hackers’ and of course, celebrity magazines and websites that encourage a voyeuristic interest in the intimate lives of others.

New multipurpose traffic cameras in the EU

A new multipurpose traffic camera which can identify license plates, recognise the distance between vehicles, see whether or not a driver is wearing a seatbelt as well as detecting speeding is being created as part of an EU program, ASSET. The program is a research project which means there is no guarantee that any member state will actually take up the scheme, but it would seem to fit with the policies of a number of them, notably the UK, which has already a nationwide network of Automatic License (or Number) Plate Recognition (ALPR or ANPR) cameras.

The story has been reported in The Guardian which notes that, despite concerns about the automation of road justice, many of the UK organisations which currently oppose speed cameras seem to be tentatively in favour of this camera which is even more restrictive of the ‘drivers’ rights’ that such organisations claim to represent… which is somewhat curious.

New Orleans Ditches Surveillance Cameras

For a while now, I have been wondering how long it would be before the combination of cost and manifest ineffectiveness made urban authorities consider removing CCTV schemes. I had thought, given its long history of public space video surveillance, was that it might be Britain where this was most like to happen. What I didn’t expect was that one of the first big examples would be from the USA, which since 2001 has been going through the kind of expansion of CCTV seen in Britain in the 1990s.

But, surprise, surprise, here is New Orleans’ Mayor, Mitch Landrieu, arguing that a mere 6 indictments in 7 years (which is the success rate of New Orleans’ video surveillance system) is not enough to justify the costs and intrusion of CCTV:

“Most of us can agree that based on the way that they were installed, based on the way that they operated and the way that they were not maintained, that they were not a good investment.”

Woah! What was that? Public space CCTV doesn’t work? Who knew?

Well actually, it isn’t just New Orleans and its particular unmaintained and faulty system. Most urban authorities already know this. Police forced already know this. I would argue that much the same could be said for those in London, which has an far, far more intensive network in public spaces, yet the police themselves admit that only 3% of street robberies are solved with the help of CCTV. The difference is that now some of them are admitting what they have known for some time. The problem is that the public still largely believe that they ‘work’ (whatever that means anyway). And ironically this means in New Orleans that the cameras are staying up, even if they are turned off (as in fact many all over the world are anyway, and many more are not actually being watched by anyone)…

Meanwhile, in the rest of the USA, Homeland Security and stimulus plan-funded Justice Department CCTV systems continue to proliferate.

US military crowdsourcing communications

Marketing site, Brandchannel, reports on a US Army program, the Joint Tactical Radio System (JTRS or ‘Jitters’), which they say is going to crowdsource video surveillance on the battlefield. Actually, if you watch the embedded video piece from the US Army itself, you’ll see that the program is much more fundamental than this, it is about integrating different radio systems and trying to make the best use of scarce EM bandwidth in order to allow all kinds of more efficient communications – which would of course include video surveillance data or any other kind of data sent over wireless.

However, all is not what Brandchannel thinks. According to Global Security, the JTRS program was already in trouble back in 2005 and rumours of its demise continued to circulate – Wired’s Danger Room reported on this back in 2007. It is still in existence but has been scaled back, the contractors have switched and the costs have risen to more than $1Bn.

The latest bit of boosterism, and claims from the JTRS people that the system will include the ability for troops to access surveillance images from military UAVs and could be in place by 2014, comes therefore in this context, and also in the context of the hacking of US military surveillance drones by insurgents using cheap Russian TV downloading software. One of the really interesting things about this is how the context of military expertise is changing: one of the key justifications for all this is the concept that US troops will already be familiar with handheld devices and streaming video etc. Network-centric warfare turns out to be no different from kids using their iPhones  to watch movies… if, of course, it ever actually works.

Real-time Video Erasure?

 

Live video erasure demonstrated

There are some reports circulating around the web that researchers from the Technical University of Ilmenau, Germany, have invented an algorithm for unobtrusively erasing objects from live digital surveillance camera footage. Now the possibility of post-hoc manipulation of video has long been known, but the idea that live images could be altered is something new. A device that could trigger such an erasure drove the plot of the superb surveillance technothriller, Whole Wide World, written by Scottish author, Paul McAuley back in 2001, but almost ten years later, reality appears to have caught up with a piece of near-future SF that already felt perilously close.

According to Ray Kurzweil’s blog, the software is being demonstrated as I write at the Symposium on Mixed and Augmented Reality (ISMAR) in Seoul, although the researchers appear to refer to their invention as ‘diminished reality’. There are links to video on the invention from both there and the university press release (above). The software appears to work by recognised shapes and removing them from the video as the feed comes in and before it reaches any display.

Soviet Leaders in Red Square, 1999
... and with Trotsky removed.

However, neither Kurzweil nor any of the other commenters on this story (e.g. BoingBoing) seem to get the potential seriousness of this development, both for resistance to surveillance and for the credibility of video surveillance: it could be a fantastic tool for privacy, or an equally fantastic tool for social and political control. It’s one thing to be able to manipulate the past (to do what Stalin did to his oppenents and airbrush them out of history -see David King’s excellent book, The Commissar Vanishes), it’s yet another thing to be unsure whether what one is watching on TV or on YouTube is ‘real’ or ‘fake’ or some combination, but it is another thing entirely to be unsure whether the supposedly live images from a surveillance camera are actually real or not…

Drone Britain

Despite the supposed anti-surveillance tendencies of the new coalition government in Britain, one kind of surveillance would seem to be expanding, as it is almost everywhere in the world: that of surveillance Unmanned Aerial Vehicles (UAVs), Micro-unmanned Aerial Vehicles (MAVs) or flying drone cameras. There are so many previous stories on this blog about drones you’d be better off searching than me providing links here!

The Guardian reported on Friday that a growing number of different agencies are either ordering drones or have plans to do so, including he Serious Organised Crime Agency (SOCA), four police forces (Merseyside, Essex, Staffordshire and the British Transport Police), the Environment Agency, and even some Fire Services (West Midlands and South Wales). This follows the story in January that there was what seemed to be an evolving secret national strategy for drones.

So far, their use has been limited not by ethical concerns but by the requirements of the Civil Aviation Authority (CAA) which insists that they must be “licensed when flown within 50 metres of a person, property or structure.” This remains its position, but it will be interesting to see how stringent are the licensing requirements as drones increase in number and whether the expansion in UAV use is in any way affected by the government’s stated policy aim to bring CCTV under stricter regulation.
