But while experienced people did better than the inexperienced people, the detection rate remained low. Adding to the complexity, while some operators were able to identify something unexpected they could not say what it was. A single detection rate metric would not be able to capture this range of results — implying that while it is helpful it would not be all-encompassing.
Little research has been done on this topic and a review of the studies so far make it clear why: Detection rate is a blunt number subject to immense nuance based on the individual circumstances in which the data was collected. The range is just too wide, greatly depending on the individual operator, the nature of the work, and the outside factors of their work. This makes the development of commercial-ready computer vision for video security that much more important. Davies, Graham, and Sonya Thasen. Scott-Brown, Kenneth C.

They were also effective in helping control crowds at large events such as Schoolies festival and the Gold Coast Indy, she said. Professor Wilson said the effectiveness of security cameras could be improved by paying more attention to where they were placed and how monitoring was conducted.
Of almost people surveyed about their views on CCTV as part of the study, about 85 per cent did not believe the cameras were an invasion of privacy. But Professor Wilson said he was "disturbed" about public apathy towards the cameras. Police Commissioner Bob Atkinson had not seen the report, but said he was "uncomfortable" with its publicised findings.
Surveillance cameras in London are not helping solve crime, according to local politicians. The city has over 10, publicly funded CCTV cameras in public areas, but only one in five crimes are solved, said Dee Doocey, a spokeswoman for the Liberal Democrats political party on the London Assembly, the elected body which determines transport and policing policy for London's 32 boroughs and the City of London itself.
Using figures obtained from the London boroughs, the Metropolitan Police Service and public transport authorities through Freedom of Information Act requests, the Liberal Democrats compared the number of crimes solved in each borough with the number of CCTV cameras installed there. Proponents of CCTV's usefulness usually focus on its role in preventing crime, rather than solving it. But although the cameras across London's public transport system allowed police officers to identify within a few days those responsible for the July 7, , tube-train bombings in the city, the cameras did nothing to prevent the attack.
Surveillance does not stop crime -- that's according to a report from the Swedish National Council for Crime Prevention. Currently there are approximately permits for surveillance cameras in Stockholm alone, a number which increases by 10 percent every year. According to an article in the Stockholm City newspaper the results were based on over 40 different research reports from four different countries. Surveillance cameras do little, if anything, to prevent late night alcohol-fuelled crime and violence on Britain's high streets, the country's most senior police officer in the field has admitted.
Graeme Gerrard, head of CCTV at the Association of Chief Police Officers, said that although Britain was now a virtual surveillance state, cameras usually failed to act as a deterrent for drunken yobs. He told a parliamentary committee that while other countries were astonished at the scale to which Britons were snooped on by the authorities, the evidence suggested CCTV had little impact on levels of late-night violence. He also admitted the public had been "misled" into believing that installing camera systems would have a big impact on anti-social behaviour.
Around million hPounds as been spent on erecting more than four million CCTV cameras across the country over the past 10 years, leading the Information Commissioner, Richard Thomas, recently to talk about "Surveillance Britain". Ministers have repeatedly stressed the benefits of CCTV on the grounds that they act as a deterrent.
But speaking to the Lords constitution committee, Mr Gerrard, deputy chief constable of the Cheshire constabulary, said: "Most of the pressure [for CCTV] comes from the public. Some of them may get disappointed when the CCTV goes in that actually I think they are perhaps misled in terms of the amount of crime that CCTV might prevent. Before CCTV can effectively deter people, they need to know the cameras are there. They have got to be thinking about the consequences of their behaviour.
It is very effective in places like car parks, where offenders are going out to break into cars, and are thinking rationally.
In terms of town centres, where a lot of the behaviour is violent behaviour, often fuelled by alcohol, people aren't thinking rationally. They get angry, the CCTV is the last thing they are thinking about. Even the presence of police officers doesn't deter the disorder on the street, so cameras are unlikely to deter them.
David Davis, the shadow home secretary, said the Government had undermined civil liberties for no apparent reason. Chris Huhne, the Liberal Democrats' home affairs spokesman, added: "We need to seriously rethink our gung-ho enthusiasm for the surveillance on every street corner in the country.
A recent Home Office study found that 80 per cent of images from CCTV cameras were of such poor quality that they were worthless as evidence. To combat the problem, Mr Gerrard said he would like all camera owners and operators to be required by law to produce high quality images using a standardised system so the police could use them effectively in court. Once again a rapist was caught on videotape, and once again cops failed to see him, police sources said Thursday. A year-old woman was raped at knifepoint inside the Van Dyke houses in Brooklyn early Thursday - a housing complex with more than cameras supposedly monitored around the clock by the NYPD.
Sources told the Daily News that at least one video camera recorded the rapist grabbing the young woman and pulling her into an elevator. The suspect hustled the young woman out of the elevator and raped her in a stairwell landing of the Brownsville complex, sources said. The actual sexual assault was not caught on video, police said. Police officials believe the attacker is the same man who raped a year-old woman March 6 in the housing complex. In both cases, the man wielded a knife and dragged his victim to a stairway landing. Both times he made similar threats, saying, "Don't scream, don't fight or I'll stab you," sources said.
The year-old victim told police she recognized the man from the neighborhood, which is why her guard was down. What horrified residents was that in both cases, the rapist, if not the violent attack, was caught on video. The suspect who raped the woman March 6 was on camera for nearly 30 minutes, sources said.
Other towns have had such cameras installed. The site aimed to add "more eyes" to cameras which might be insufficiently monitored. The officers, in the so-called viper units, call other cops to respond to criminal activity. Criminology and Criminal Justice , May , Vol. Submit Search.
Roughly cameras feed live video to 30 small TV monitors. Each camera's image flashes for only seven seconds. Deputy Police Commissioner Paul Browne said the actual sex assault was not filmed. He said there was no indiction that any suspicious action was transmitted in the seven-second bursts. The video monitors are staffed mostly by cops who are on medical leave or face disciplinary action and cannot carry a weapon.
The officers, in the so-called viper units, call other cops to respond to criminal activity. Police officials know Bennie Nichols well. In Dallas County, he has been convicted of breaking into cars at least 16 times since He was convicted of car burglary three times last year and served days in jail.
