Closed circuit television, better known as CCTV, is technology designed for visual surveillance. Its purpose is to monitor activities in a number of environments. It works by way of a dedicated communication link between a monitor and cameras (also known as a fixed link.)

Up until a decade ago CCTV didn’t get much notice. Now it’s use has grown exponentially. The UK stands out as an all-time high user of CCTV, finding the monitoring systems useful for public facilities, residential subdivisions, and parking lots. The budget for its annual use runs into the hundreds of millions of dollars.

Many thousands of CCTV cameras, commissioned by public safety organizations, and neighborhood watch or homeowners associations, help reduce safety issues in areas such as buses and terminals, taxis and stands, trains and train stations, phone booths, vending machines and ATM locations. The cities and towns themselves are protecting their major thoroughfares and business districts with CCTV equipment that includes camera capacity for zooming, full tilting, panning and even infrared for night viewing. Hospitals are starting to use closed circuit television products to keep an eye on the interactions between hospitalized children and visiting parents or family members they suspect of molesting or otherwise abusing them.

While the technology was first seen in Britain as a deterrent and watchdog for major crime prevention, its use has increasingly come into play to catch in the act of, or deter from the act, of considerably lesser crimes. Which may or may not be seen as a good thing. The concern here is whether or not “big brother” will start watching. Just how far will they take it?

Where they’ve taken it from is from the prevention of physical assault crime and serious but lesser life threatening crimes such as burglary and car jacking to a current preponderance of smaller infraction oversight and prevention. In the UK, it’s not uncommon for CCTV to catch in the act someone whose crime is an attempt to commit a traffic violation, urinate in public, be publicly intoxicated and – horrible of horribles – fail to feed the parking meter. Underage smoking and drinking, use of illegal substances and occasions of sexual and racial harassment have also been exposed through closed circuit television wizardry.

Whether this British CCTV craze has really been a significant crime deterrent is hard to say.

Some public safety authorities claim reduction of violent and other crimes as high as 75 percent, stating CCTV as the reason behind this. Others dispute the statistics, stating that the results are flawed due to inept reporting and interpretation. One conjecture is that, because CCTV is much more prevalent in more affluent areas, criminals have merely moved down the road to those lower income areas whose residents and administrators cannot afford the costly CCTV system.

One result of CCTV’s capturing crimes in action is that a preponderance of alleged perpetrators, faced with the knowledge that their criminal actions have been captured on TV, are opting to plead guilty, saving taxpayers the cost of a lengthy trial. While this may be a good thing at first glance, the jury is really still out on whether this is justice served to the “innocent until proven guilty” or not.

How Can a CCTV Security System Help?

How Can a CCTV Security System Help?

Article by Groshan Fabiola









One of the most frequently asked questions about the CCTV system is that inquiring upon its nature. CCTV, short for Closed Circuit Television, is a surveillance technology which monitors a wide range of activities and environments. The CCTV system is based on a communication link between a camera and a specific monitor. Many towns and cities resort to CCTV security systems, which has led to an unprecedented growth in the amount of money spent on surveillance systems. CCTV security systems are now used in public areas such as city centers, parking lots, public facilities, buses, taxis, phone booths etc. Actually, statistics say that the surveillance industry grows with up to twenty percent every year. CCTV security systems are also installed on private property, not just public places.

Evidence of domestic violence can be collected by means of a CCTV system, installing a camera inside the victims’ homes. A similar type of surveillance is used inside hospitals in cases of supposedly abused children, in order to monitor their parents’ activities and behavior.

In the early stages, CCTV security systems were used to decrease crime rate such as burglaries or car thefts. More recently, CCTV systems pick up on more minor offenses such as urinating in public, drunkenness, traffic violation. Those who evade the meters in a parking lot can also be caught on camera. Underage smoking, sexual or racial harassment, drug use, all of these crimes are the subject of CCTV system monitoring. Public order is now more likely to be kept with the use of CCTV security systems, which have become the solution to the serious problem that is urban dysfunction. But the police are not the only promoters of security through CCTV systems. Politicians also encourage installation of such systems in order to control crime.

The CCTV system also has its opponents, but whenever these critics speak up, people who are frightened by crime consider them to be nothing but enemies of everyone’s best interest.

As far as the technology used in a CCTV system goes, it suffices to say that some of these systems can be very sophisticated. They can be assisted by a computer, can detect motion, can have night vision and images of excellent clarity. Another amazing thing about the cameras on a CCTV security system is that they can focus on a single object from a crowded environment and follow that one object. They provide high definition images from which faces can be recognized. The time needed for a system to identify one face out of several thousands is less than a second. The system is mostly used in airports where terrorists may enter a country.

Since the CCTV cameras have often become targets of attacks, more and more of them now have a casing which is bullet proof, or are covered by other cameras installed nearby.

The question still remains whether CCTV security systems reduce crime. The answer is that they are most likely to prevent it. Those in favor of such surveillance systems have at least one argument. CCTV systems reduce the number of the so-called opportunistic crimes, that is the crimes committed when people decide to take advantage of a certain situation. In the same way, crimes in parking lots have reportedly dropped by almost ninety percent.

The conclusion is that, although CCTV security systems may not be as efficient as their supporters portray them, at least they appeal to common people, who now feel much safer when going shopping, for instance.

The Crazy Days of CB Radio

The Crazy Days of CB Radio

Article by Jim Monahan









During the great citizen’s band or CB radio craze of the late 1970s, it seemed like everyone had to have a CB radio and talk like a truck drive while driving down the highway. CB radio is an unlicensed local radio service for individuals and small businesses. CB radios are quite inexpensive and can be very handy.

As you might expect, filmmakers and entertainers use a fair amount of artistic license in their portrayal of CB activities. If you start off your CB career with unrealistic expectations, you’re bound to be disappointed so let’s begin with the basics. CB radio was created in the 1950s by the FCC in and effort to encourage citizen’s to use the new radio technology.

The CB service provides individuals and small businesses with a low-cost way to stay in touch and coordinate their day-to-day activities up to a 5 or 10 mile range. If this sounds like what you need, CB might be just what you’re looking for.

Many two-way radio services require you to purchase a license from the FCC. The CB radio service isn’t one of them. The FCC does have some rules that you should follow though. You can find the rules tucked into the operating manual of your radio. You can also download them on the Internet. The rules are easy to read and are organized as a list of common questions. They include technical rules about radios and antennas as well as what you can and can’t do on the air.

What you can’t do is fairly straightforward and laid out clearly in CB rule 13. You can’t advertise materials for sale or a political campaign, cuss, play music, or rebroadcast radio or TV programming. You’re also forbidden to intentionally interfere with other stations and make false transmissions particularly distress calls.

Each CB radio can operate on any of 40 channels centered on frequencies from 26.965 to 27.405 MHz. This frequency range is near the upper limit of the traditional shortwave or HF band tucked in between the Amateur Radio 10-meter band and a band used by business radios.

You can operate in regular AM mode or select either upper or lower sideband a variation of AM discussed later in this chapter. That gives you 120 different choices about where to operate.

By far, the most popular use of CB radio today is in vehicles. Using CB for business-to-business communications is less common than it was in the halcyon days of CB radio but farms, towing companies, local delivery services, taxis, and other mobile users still find CB radios very useful.

Professional drivers use CB radio for everything from keeping an eye on speed traps to checking in at the delivery dock and making idle conversation with anyone in range. Right behind the professionals are private citizens who use CB radio when they drive for many of the same reasons.

Sat Nav Systems

Sat Nav Systems

Article by Jim Haskard









Satellite navigation systems are electronic receivers that determine their location (longitude, latitude and altitude) to within a few meters using time signals transmitted by radio from satellites.

Why get one?

The main reason for buying a sat nav system is if you easily get lost, or your job involves spending a large amount of your time on the road e.g a taxi driver. Although a map is cheaper sat nav systems can guide you to your destination with voice commands and also have a screen displaying exactly where you are.Although there have been incidents involving people driving onto train tracks directed by their sat nav and having their cars destroyed by train, most sat nav systems work just fine.

Which one to buy

There are so many sat nav systems on the market it can be hard to decide which one to buy. One of the cheapest and most popular is the TomTom one which is priced at around ?150. The system offers plug in and go usability as all the software is preloaded on the sd card. It comes with a high quality touch screen, is portable and lightweight. You have the option for choosing routes i.e shortest, fastest avoiding motorways etc. One of the best features is the postcode navigation which allows you to input a postcode and be guided to your destination.

Another popular system is the Navman F20 which has the same specifications as the TomTom one but also has a nearest parking and petrol button which when pressed will direct you to the nearest car park or petrol station. It is priced at £115.

The Garmin nuvi 660 is more expensive than the two systems above but has some cool features such as integrating Bluetooth technology so that you can make hands free mobile phone calls. As with the other two systems the maps come preloaded so it is ready to go out of the box. It comes with a 4.3 inch widescreen display and mp3/audio playback. It is priced at around £300.

There are many more great sat nav systems out there but there isn’t time to write about all of them. When buying one make sure you shop around to get the best price.

Shuttleworth firm backs SA Cab

Shuttleworth firm backs SA Cab Sep 19 2007 03:34 PM Melissa Britz

Cape Town – HBD Venture Capital, started by local entrepreneur and afronaut Mark Shuttleworth, has invested R10m in a local metered taxi operator.

The company started by Shuttleworth in 2000 invests in early stage SA companies with high growth potential.

Eben van Heerden, portfolio manager at HBD Venture Capital said: “…With the 2010 World Cup set to attract floods of visitors and the government spending R28bn on public transport projects such as the Gautrain, there is a growing demand for a safe, efficient alternative to private cars.”

SA Cab plans to expand its current operations to become a national metered taxi network that delivers a world-class service.

SA cab operates a number of its own cabs so it understands the industry. “But the true jewel in its crown is its independant call centre run by Diplomat Navigator (pty) which can, for the first time in SA, connect taxi operators throughout the country via a tollfree number and GPS tracking”, said Van Heerden.

Craig Robinson, CEO of SA Cab, told Finweek’s Ben Kelly that its call centre technology is very effective. “Before we installed it, we conducted extensive research in Britain and the US and chose a solution that could be tailored to the SA market.”

We chose the Diplomat booking and dispatch software sytem supplied by Navigator Software systems in the UK. http://www.navigator-metro.com

Stewart Harding Technical Director of the SA call centre has been largely responsible for the development of management and hardware solutions appropriate for the South African Markets.

Independent taxi operators pay a fee to subscribe to the call centre business (Diplomat Navigator PTY), they are then connected via a cellular data link manufactured by Diplomat Ltd in the UK. http://www.diplomat.co.uk.

This device called the Lynx box relays GPS and Fare data to the contact centre. Using that link and mapping software, the centre is able to determine which vehicle is best located to serve the customer and that taxi is dispatched.

Safety concerns are a major consideration for SA Cab.

“We found that incredibly strict screening processes are built into the call centre technology. Each day, when the GPRS is switched on in a taxi, a number of details are checked including whether the driver’s license is valid and whether personal insurance is fully paid.”

“All cars must obtain a new roadworthy certificate and be registered in terms of public transport requirements. If any requirements are not met, the taxi is no longer able to operate in the SA Cab network,”
