The History of Video Surveillance

Mention video surveillance and most people think of video cameras mounted in the corners of train stations and banks or private detectives video taping an erring spouse for a messy divorce case. The truth is that the history of video surveillance is much more complex and goes back much farther than most people realize.

If you consider video in the simplest of terms, video surveillance began with simple closed circuit television monitoring. As early as 1965, there were press reports in the United States suggesting police use of surveillance cameras in public places. In 1969, police cameras were installed in the New York City Municipal Building near City Hall. The practice soon spread to other cities, with closed circuit television (CCTV) systems watched by officers at all times.

Analog beginnings spur video surveillance

When video cassette recorders hit the market, video surveillance really hit its stride. Analog technology using taped video cassette recordings meant surveillance could be preserved on tape as evidence. The seventies saw an explosion around the world in the use of video surveillance in everything from law enforcement to traffic control and divorce proceedings.

England installed video surveillance systems in four major Underground Train Stations in 1975 and began monitoring traffic flow on major highway arteries about the same time. In the United States, the use of video surveillance wasn't quite as prevalent until the 1980's for public areas, but store owners and banks quickly understood the value of it.

Businesses that were prone to theft, including banks, mini-marts and gas stations, began mounting video surveillance systems as a deterrent and in hopes of apprehending thieves, particularly in high crime areas.

The insurance industry also found video surveillance compelling worker's compensation fraud, bogus accident claims and a variety of other cases began to turn in the industry's favor when they could provide tapes of supposedly disabled workers doing the limbo at a family reunion.

For the private citizen, analog technology was primarily used in the 1970's and 1980's for capturing the worst side of human nature cheating spouses and poor parenting. Private detectives were able to provide more graphic and compelling evidence of affairs and parental stupidity with film than with still shots, and video tapes became frequent evidence in family court.

The drawback in many cases was that after a while, owners and employees would become complacent and not change the tapes daily or the tapes would wear out after months of being re-used. There was also the problem of recording at night or in low light. While the concept was good, the technology hadn't yet peaked. The next step was the Charged Coupled Device camera (CCD), which used microchip computer technology. These new cameras broadened the practical applications of video surveillance by allowing low light and night recording possible.

In the 1990's another advancement in the history of video surveillance made great strides in practicality Digital Multiplexing. When digital multiplexer units became affordable it revolutionized the surveillance industry by enabling recording on several cameras at once (more than a dozen at time in most cases). Digital multiplex also added features like time-lapse and motion-only recording, which saved a great deal of wasted videotape.

By the mid-1990's, ATM's across the United States and in most parts of the world had video cameras installed to record all transactions. After the first attack on the World Trade Center in February of 1993, the New York Police Department, FBI and CIA all install surveillance cameras throughout the area. Soon many countries are also using either CCTV or video taped surveillance to cover major sporting events that could be potential hot spots, including the World Cup Soccer games at Giants Stadium in 1994.

Digital makes video surveillance faster, clearer, more efficient

Digital video surveillance made complete sense as the price of digital recording dropped with the computer revolution. Rather than changing tapes daily, the user could reliably record a month's worth of surveillance on hard drive because of compression capability and low cost.

The images recorded digitally were so much clearer than the often grainy images recorded with analog that recognition was immediately improved for police, private investigators and others utilizing video surveillance for identification purposes. With digital technology you could also manipulate the images to improve clarity even further by adding light, enhancing the image, zooming in on frames, etc.

The second wave of increased video surveillance corresponded with the emergence of digital in the United States. From 1997 on, police departments across the country installed more and more video surveillance cameras in public buildings, housing projects and areas like New York's Washington Square Park. The NYPD also began using mobile surveillance vans at political rallies and other large gatherings (including festivals and parades) under the auspices of the Technical Assistance Response Unit (TARU).

In-home use soars with advent of nanny cams

As more women went back to full-time careers in the 90's, digital video surveillance manufacturers found a niche market that hadn't previously been tapped monitoring what was going on at home when parents were gone. The nanny cam was a huge success, providing a way for parents to observe what nannies and housekeepers were really doing while at home with the kids.

The popularity of these cameras pushed the industry to develop ever-smaller, higher resolution cameras that could be hidden almost anywhere. The result was a boon to industry development, with new versions of digital video surveillance cameras coming out nearly every month.

9/11 redefines video surveillance for the future

Nothing changed the concept of or the public's awareness of video surveillance as much as the tragic events of September 11, 2001 when the World Trade Center was attacked by terrorists. Where once people saw video surveillance as an issue that might never affect them, it was now an issue of immediate and lasting importance.

Software developers began refining programs that would enhance video surveillance, including facial recognition programs that could compare various key facial feature points in order to match recorded faces to known mug shots or photographs of terrorists or criminals. While the earlier versions weren't always reliable, the later versions became more refined and were phased into use by law enforcement in some areas. In May of 2002, the United States Parks Service installed face recognition software on the computer video surveillance cameras at the Statue of Liberty and Ellis Island.

That same year, the Sydney International Airport in Australia installed SmartGate, an automated border crossing system used for all airline crew members. Using photo biometrics, the video surveillance systems scans the crew member's face and compares it to the passport photo and confirms the match in less than ten seconds, speeding the border process markedly.

In December of 2003, Royal Palm Middle School in Phoenix, Arizona installed face recognition video surveillance as a pilot program for tracking missing children and registered sex offenders. It has split the community, but is supported by many in favor of it as a potential way to track abductors and child molesters.

Vinyl Makes A Comeback

I remember reading this TIME article a year ago explaining vinyl record sales going up in the midst of the digital music age.

VINYL GETS ITS GROOVE BACK

From college dorm rooms to high school sleepovers, an all-but-extinct music medium has been showing up lately. And we don't mean CDs. Vinyl records, especially the full-length LPs that helped define the golden era of rock in the 1960s and '70s, are suddenly cool again. Some of the new fans are baby boomers nostalgic for their youth. But to the surprise and delight of music executives, increasing numbers of the iPod generation are also purchasing turntables (or dusting off Dad's), buying long-playing vinyl records and giving them a spin.

Like the comeback of Puma sneakers or vintage T shirts, vinyl's resurgence has benefited from its retro-rock aura. Many young listeners discovered LPs after they rifled through their parents' collections looking for oldies and found that they liked the warmer sound quality of records, the more elaborate album covers and liner notes that come with them, and the experience of putting one on and sharing it with friends, as opposed to plugging in some earbuds and listening alone. "Bad sound on an iPod has had an impact on a lot of people going back to vinyl," says David MacRunnel, a 15-year-old high school sophomore from Creve Coeur, Mo., who owns more than 1,000 records.

The music industry, hoping to find another revenue source that doesn't easily lend itself to illegal downloads, has happily jumped on the bandwagon. Contemporary artists like the Killers and Ryan Adams have begun issuing their new releases on vinyl in addition to the CD and MP3 formats. As an extra lure, many labels are including coupons for free audio downloads with their vinyl albums so that Generation Y music fans can get the best of both worlds: high-quality sound at home and iPod portability for the road. Also, vinyl's different shapes (hearts, triangles) and eye-catching designs (bright colors, sparkles) are created to appeal to a younger audience. While new records sell for about $14, used LPs go for as little as a penny--perfect for a teenager's budget--or as much as $2,400 for a collectible, autographed copy of Beck's Steve Threw Up.

Vinyl records are just a small scratch on the surface when it comes to total album sales--only about 0.2%, compared to 10% for digital downloads and 89.7% for CDs, according to Nielsen SoundScan--but these numbers may underrepresent the vinyl trend since they don't always include sales at smaller indie shops where vinyl does best. Still, 990,000 vinyl albums were sold in 2007, up 15.4% from the 858,000 units bought in 2006. Mike Dreese, CEO of Newbury Comics, a New England chain of independent music retailers that sells LPs and CDs, says his vinyl sales were up 37% last year, and Patrick Amory, general manager of indie label Matador Records, whose artists include Cat Power and the New Pornographers, claims, "We can't keep up with the demand."

Big players are starting to take notice too. "It's not a significant part of our business, but there is enough there for me to take someone and have half their time devoted to making vinyl a real business," says John Esposito, president and CEO of WEA Corp., the U.S. distribution company of Warner Music Group, which posted a 30% increase in LP sales last year. In October, Amazon.com introduced a vinyl-only store and increased its selection to 150,000 titles across 20 genres. Its biggest sellers? Alternative rock, followed by classic rock albums. "I'm not saying vinyl will become a mainstream format, just like gourmet eating is not going to take over from McDonald's," says Michael Fremer, senior contributing editor at Stereophile. "But there is a growing group of people who are going back to a high-resolution format." Here are some of the reasons they're doing it and why you might want to consider it:

Sound quality LPs generally exhibit a warmer, more nuanced sound than CDs and digital downloads. MP3 files tend to produce tinnier notes, especially if compressed into a lower-resolution format that pares down the sonic information. "Most things sound better on vinyl, even with the crackles and pops and hisses," says MacRunnel, the young Missouri record collector.

Album extras Large album covers with imaginative graphics, pullout photos (some even have full-size posters tucked in the sleeve) and liner notes are a big draw for young fans. "Alternative rock used to have 16-page booklets and album sleeves, but with iTunes there isn't anything collectible to show I own a piece of this artist," says Dreese of Newbury Comics. In a nod to modern technology, albums known as picture discs come with an image of the band or artist printed on the vinyl. "People who are used to CDs see the artwork and the colored vinyl, and they think it's really cool," says Jordan Yates, 15, a Nashville-based vinyl enthusiast. Some LP releases even come with bonus tracks not on the CD version, giving customers added value.

Social experience Crowding around a record player to listen to a new album with friends, discussing the foldout photos, even getting up to flip over a record makes vinyl a more socially interactive way to enjoy music. "As far as a communal experience, like with family and friends, it feels better to listen to vinyl," says Jason Bini, 24, a recent graduate of Fordham University. "It's definitely more social."
