Intelligent Video Surveillance
Public video surveillance for commercial and private purposes is not a recent phenomenon. The private sector began using video surveillance in banks in the early 1960s, as mandated by federal law, and later in commercial buildings. By the 1970s, video surveillance was also in use in hospitals, all-night convenience stores, art galleries, and in many other commercial locations. Video technology at the time was limited to passively record events, with little or no means for remote active monitoring. On many occasions, police officials were unable to use remote video cameras images to prosecute criminals because quick movements by the criminals resulted in blurred pictures.
Video technology improved in the 1990s with digital technology. These powerful new advances in video technology extend its range. New digital video cameras have powerful zoom lenses which can tilt and pan to offer a 360-degree coverage. They also are able to gather sharp, clear images in extremely low light. Moreover, new digital video technology requires less labor intensive monitoring. Digital video surveillance cameras can link computer data processing power with sensor or motion detectors to filter out unrelated activities. Such systems can search through a video database of events, allowing the user to isolate only those details in which a particular image occurs. This technology helps police with criminal investigations in order to solve crimes. An executive for a major security firm contends that, "new surveillance cameras document indisputable events with incredibly high resolution."
Many businesses in the United States have invested heavily in the new video surveillance technology to protect products and to promote safe workplace and consumer environments. A recent nationwide survey of a wide variety of companies found that 75 percent utilize video surveillance. Private sector video surveillance technology is operated in a wide variety of industries: restaurants/bars, hotels/motels, retailing, industry/manufacturing, health care, financial/insurance/banking, transportation and distribution, and utilities/communications.
Digital video surveillance is also very common in the American workplace. CCTV surveillance is one of 5 legally approved methods to observe employees. Businesses also rely on digital video surveillance to monitor cash registers and verify time clock compliance, watch employees in training, as well as to help with employee productivity. Employee productivity can be improved in areas like the kitchen or retail sales floor, just by watching what employees do and providing feedback, both positive and negative.
Some research suggests that American workers feel safer in the presence of security camera equipment. Digital video surveillance has proven to be a significant deterrent to criminal activity and provides valuable evidence in criminal lawsuits. Some businesses have used their footage to refute both customer and employee claims that could have been lengthy and costly lawsuits. Safety can be improved as well. With video cameras positioned outside your back door you always know who is on the other side.
Events such as the World Trade Center bombing, the Oklahoma City bombing, and the closure of Pennsylvania Avenue at the White House have raised public concerns about security. This in turn has made the video surveillance industry more acceptable to the general public. A leading security industry spokesperson asserts, "years ago shoppers objected to electronic eyes recording their moves; today it's not only accepted, it's preferred."

Do You Really Need A Home Video Surveillance System?
When they were first introduced, video surveillance systems were mostly used with medium to large businesses. These days however, they are becoming more and more common in homes. Video surveillance security systems are also known as Closed Circuit TV (CCTV) and are used to monitor certain areas around the home and help to protect it from burglars and thieves.
The monitor is a key aspect to the video surveillance setup. The monitor will feed the video from the cameras that make up the system. The monitors are normally black and white and feature a higher resolution than that of a standard television set. Monitors vary in size and resolution, although the standard resolution is between 500 and 1000 lines.
Cameras are also important. When setting up the home video surveillance system, the cameras are placed strategically around the outside of the home, in the most vulnerable areas. They should be set up in areas where they are nearly impossible to see. The cameras are always working, sending the video transmissions to the monitors on a frequent basis.
Coaxial cables are also a must have for video surveillance systems. The coaxial cables are what transfers the video signals from the camera to the monitor. The cables are available in a variety of sizes.You can get them from any local electronics store in your area. Your home video surveillance system will come with coaxial cables, although you may need more depending on where you plan to set the cameras up at.
Home video surveillance systems also use switchers. Switchers allow you to run multiple camera feeds to one monitor. Normally, a switcher will cycle through feeds unless it detects movement going on around a camera. When the switcher detects any type of movement, it will automatically lock in to the camera that has detected the movement.
some video surveillance systems make full use of VCRs and you may get them for the home that. These systems will use the VCR to record any live video feed that you program. This can come in handy if you travel a lot, as the VCR can capture a break in as it happens. If you end up going to court or to the police, you can use the video tape as evidence.VCRs can catch burglars in the act – especially if you set up the camera location in a way which makes it hard to see.
By utilizing the combination of a monitor and video camera, home video surveillance systems can easily catch burglaries and break-ins. They are very affordable these days, and used in thousands of homes throughout North America. If you’ve been looking for the ideal way to protect your home – a home video surveillance system is something you should look into immediately.

Homeland Security Wants to Spy on 4 Square Miles at Once (Wired)
The Department of Homeland Security wants to take a cue from the military's
experience with wartime surveillance. It's looking for a camera that can spy
on four square miles -- entire neighborhoods -- at once, just like the
military has. Only the people the military snoops on aren't protected by the
Constitution.
