Nobody likes a cluttered desktop
OK, maybe somebody somewhere in the world likes a cluttered desktop, but it is the goal of most office workers to keep their work area clean and clutter-free. Many studies suggest that such an environment is conducive to creativity, brainstorming and productivity. Whether or not this is true, it looks bad and low-tech.

Wirless is hot
With the introduction of new Wimax standards (the underlying technology driving wireless USB and wireless FireWire, among other emerging wireless technologies) just about everything except the power supply and monitor are commonly found in a wireless format.

Welcome Wireless VGA
The limitation on a wireless VGA (adaptable to DVI or HDMI) is no more - retailers are now offering wireless VGA adapters capable of transmitting a wireless signal to your monitor. The monitor still requires a power adapter, but you now have the flexibility of locating your computer in another room or section of the office. This is very useful when dealing with a media center or a computer powering multiple remote displays.

Most vendors do not have residential permits for these devices…yet
Right now, unfortunately, these are not approved for residential use by the FCC. This problem, however, should be resolved soon so wireless VGA can be a reality in residential areas. For now remember that you need not be tethered to your computer while working in an office.

Preston Wily is the marketing director for Sewell Direct, an internet retailer of computer hardware and accessories such as a wireless VGA adapter.

While spy cameras can be used by anyone, wearable spy cameras usually serve the purposes of law enforcement. These little unnoticeable cams are ideal for private investigators, cover surveillance, and secret agents but this doesn’t mean that they are not available to the public. Several companies launched models buyable by regular people.

Nearly everyone has seen a James Bond movie and remembers the high tech cameras inside pens or glasses. This is no longer a dream. Specialized shops sell spy cameras perfectly hidden inside sunglasses, pagers, pens, and other everyday items. Wearable spy cameras are also found in several other items as well. They can be attached to a helmet, for example, to record a bike ride or parachute jump. Such cameras come with added features like being waterproof, small or lightweight. There is also the possibility of having a camcorder in your backpack and a lens mounted on your hat that can record events without being held.

Of all the possible types of wearable spy cameras available to the public the most appreciated are the concealed ones, such as a pen camera. They are very easy to hide since people usually don’t look for them. Hidden in plain sight, such cams will record important evidence, like a testimony, or just about anything one might want to record with or without the people involved giving permission. Problems can arise if subjects don’t consent to being filmed, but it doesn’t matter in many instances, such as catching a cheating spouse.

Whether someone wants to do a little espionage, have fun, or take pictures where regular cameras are restricted, a wearable spy camera is perfect.

Spy cams are small cameras that transmit video output to a remote receiver. What’s special about them in comparison to other types of cameras is the fact that they are very small, sometimes even as small as a key after they are hidden. A spy cam can be useful in a variety of situations. They are used mostly for surveillance and don’t harm anybody. A particular type of spy camera cameras is the spy web cam. The difference between a spy web cam and a normal spy cam is that the data is transmitted live on the Internet, rather than to a receiver.

Such cameras are used to spy on people, places, and actions in nature.

Browsing the net, one will surely find websites that have such direct live feed. Some of them are displaying adult content and others give viewers the chance to watch something unusual. Live Internet broadcasts such as pay-per-view events usually use more advanced technology than spy web cams. More advanced cameras are utilized for the benefit of the normal paying customer.

Spy web cams are often intended for somewhat immoral reasons. Many Internet sites use this technology to broadcast live places like a public bathroom, a sauna, a strip club, or something else related to naked women, men, or sex. Also, a type of worm has been developed that basically takes control of a normal web cam and broadcasts the signal and the live image to a certain person. Of course, this is against the law, but many people still get a way with doing it.

While some people use spy web cams for illegal reasons, they are usually used for wholesome purposes. People can find hundreds of sites that give viewers a live feedback of a local area or of certain animals in their natural habitat, as well as other actions that give pleasure to people without involving anything adult. They can be useful but at the same time they can be used to spy on unsuspecting people.

Spy cams are becoming a profitable new industry and are beginning to be used more regularly worldwide. Spy cams are often used for security or surveillance, but they are used for other means as well. A spy cam is simply a small camera that can be hidden and is very hard to notice or trace.

Spy cam technology varies from model to model. There are some spy cams on the market that are as small as a battery, while other cameras cam be hidden inside a pen. Specialized shops sell a wide variety of spy cams that are versatile enough to be used in any way the buyer sees fit. Spy cam equipment can vary in price from 10 dollars for old models bought secondhand, to thousands of dollars for state of the art technology that includes a monitor and other accessories.

Many people believe that this boom in spy cam technology started off with Allen Hunt’s famous words: “Smile, You’re on Candid Camera”. Fans of the famous TV program Candid Camera were among the first consumers to realize that spy cams could be used for purposes other than security and surveillance, and people started to understand the potential that this technology offers. Unfortunately, many problems arose as spy cam use increased, leading people to debate the topic of “Spy Cams – friend or foe”. Many people value their privacy and do not like the idea that others can use small spy cams to watch, and broadcast, their every move. Other people see spy cams as simple harmless fun.

Spy cam use is widespread, some of the many industries that use them include security companies, limo services, private detectives, and concerned parents who want to watch their babysitter. Many employers use spy cams to keep tabs on their employees and make sure that they are working efficiently.

As time passes, and society’s need for increased security advances, limitations in current technology become apparent. Police officers on the job, private eyes who need to satisfy their customers, and private citizens who want to keep their property secure all need state of the art surveillance equipment. Several companies recognized the demand and began manufacturing sophisticated spy camera surveillance supplies. This industry evolves with each passing year, delivering more versatile models by the minute.

Most people have probably seen movies where detectives organize a stakeout or a surveillance operation. These activities have become much easier and simpler with the advent of new spy camera surveillance tools. Several modern cameras are small enough to be virtually undetectable to the human eye and are used to full effect by police and private detectives, providing valuable information and evidence. Private citizens can also use this technology for their own security needs. People can use high tech surveillance cameras to keep an eye on their valuables or to alert them to any intruders on their property.

Spy cams can be used for protection purposes, too. Several banks and public buildings have surveillance equipment that is small enough to go unnoticed by the majority of people. These types of cameras are perfect for blending into the background while still recording all of the activity in the area.

Many important people use spy camera surveillance for protection, from a local banker to the President of the United States of America. Some types of spy surveillance equipment include nanny, regular, hidden, digital, pinhole, and wearable spy cameras. Although such equipment is usually used for security and protection, there are situations where they are used for illegal activities like extortion and blackmail. Such examples are few and far between, and spy camera surveillance tools are usually used to keep people safe.

Pinhole spy cameras are defined as state of the art cameras that are so small that they can be hidden inside a picture frame, a stuffed animal, a lamp, or anything else. Most of them are as small as a quarter, and some even newer models are smaller. As one can imagine, the lens is not as “big” as the spy cam but offers a wide viewing range and is practically the only part of the spying instrument that cannot be hidden. Since the camera is so small and can be hidden, they are virtually impossible to detect.

Usually, all that is needed to operate such cameras is a VCR, and a pair of batteries or a 9V battery, depending on the model. Many pinhole spy cameras offer even more than just recording. For example, there are models that have built in smoke detectors, air purifiers, or motion sensors. New pinhole spy camera technology is evolving constantly. The models bought most often are the ones with built in motion sensors, as they start recording only when motion is detected, saving the user lots of time and videotape.

Pinhole spy cameras are often used for surveillance and for protection. Many employers use them to keep track of worker productivity and to keep employees from stealing supplies, and may concerned parents used them to keep an eye on their babysitter.

The signal from pinhole spy cameras can be transmitted to a live feed or it can be recorded for later viewing. These options, along with the relatively low price of the equipment, make pinhole spy cameras a good security investment.

Who needs an LCD display? Well, if you’re like me, having one huge hunk of a monitor sitting on your desktop is just not feasible. Not only does it take up desk space, but there’s just simply no need for all of the physical mass, right?

Welcome LCD displays—the computer monitors of the present and future. From year to year these computer peripherals tend to get smaller and thinner in size with twice the power and benefits. Well, stay on the look out for more to come because I am certain that our current flat monitors have not reached their journey’s end yet. An LCD (which stands for liquid crystal display, by the way) works much differently than your CRT, mostly because they don’t project light, and therefore use much smaller units during display.

Let’s talk about the benefits of a flat monitor:

1.) They produce less heat

2.) They use less electricity

3.) Because they use digital signals, the display is sharper and clean

4.) Speakers are generally included in the screen, so you don’t have to worry about cluttering your desk with speakers anymore

When deciding on purchasing your LCD display, be prepared to spend at least $200, and definitely look into a 19 inch display (as opposed to a 17 inch). From Sam’s Club to Sears to Circuit City, it’s certain that you’ll find the display you need for the price you want to pay. Just do a little comparison shopping, and pat yourself on the back for making a purchase that will clear up your desk clutter and save you some space!

Whether you are crunching figures at a front office job or crouched over a blood and gore video game in some deep recess of your room, there is the right kind of screen available to suit your needs.

Monitors are one segment where you are truly spoilt for choice.

Be it a 15-inch, 17-inch or 19-inch CRT monitor* or a sleeker range of LCD screens*, there is a wide range to fit your budget. Hardware Software Articles: http://www.hardwaresoftwarearticles.com/archive/index.php/

*Size and resolution*

There are two aspects you must consider when selecting a monitor: physical size and resolution.

Screen size is the diagonal screen measurement, usually in inches. For instance, a computer monitor display might be 14 inches wide and 11 inches tall. This same screen has a diagonal measurement of 19 inches, which is the screen size.

Monitors also have an aspect ratio.

This is the ratio between the horizontal dimension and the vertical dimension (horizontal dimension divided by vertical dimension). Common monitor aspect ratios are 4:3 (1.3333) and 5:4 (1.25). Basics: http://www.hardwaresoftwarearticles.com/archive/index.php/f-2.html

A 4:3 aspect ratio means the picture is 4 units wide for every three units of height.

Wide screen monitors are easier on the eye (and much more expensive).

The higher the resolution, the greater the ability to render more detail. If you work with graphics or enjoy graphic-intensive games, you will need a monitor with higher resolution.

With most currently available models being flat screened, the difference is in the size and picture quality. A resolution of 1024 x 768 is a good one for most users.

*CRT monitors*

If you’ve decided to get a new CRT, make sure it has a sufficiently high refresh rate. This refers to how often the screen is redrawn per second. With low refresh rates you can get screen flicker and eyestrain. Virus: http://www.hardwaresoftwarearticles.com/archive/index.php/f-14.html

Aim for a rate of 75 Hz for a monitor up to 17 inches in size and 85 Hz for any larger monitor.

Another consideration for CRTs is dot pitch. The smaller the dot pitch, the sharper the image. Opt for a dot pitch of 0.26 mm or smaller.

CRTs function very well at multiple resolutions, can display detailed graphics and can be viewed comfortably from wider angles.

*LCD screens*

One of the primary disadvantages of LCDs when compared to CRTs is their limited viewing angle. When viewing a LCD straight on, it looks great. But the screen will appear washed-out if you move your head over to the side and look at it from a wider angle.

Also, LCDs are optimised to perform at a single resolution. Low-end LCDs have viewing angles of only 100 degrees, which won’t give everyone crowded round your desk a clear view.

For a standard 15-inch LCD, try to get a 140 degree viewing angle. Increase that by 20-40 degrees when shopping for an 18-inch LCD.

The brightness of LCD monitors is an important factor. LCD monitors have several backlights that provide illumination. The backlights in a LCD are good for 10,000 to 50,000 hours of operation. Ensure that the backlights come with at least a one-year warranty. Messenger: http://www.hardwaresoftwarearticles.com/archive/index.php/f-7.html

*Making a choice*

LCD screens generally cause lesser strain to eyes than CRT monitors.

CRTs have better graphics, but they tend to occupy five times as much space.

If you are a gaming freak, then a CRT is a better option as it is best for any graphic interface.

If you want the sleek look, an LCD is meant for you. It is widely used in banks and treasury and trading rooms.

Take a good look at your notebook computer screen. Do you find some tiny dark spots? You could have dead pixels. One of the most expensive parts of your notebook computer is the LCD screen.

LCD’s are highly sensitive and any amount of pressure, touching or handling may damage it. As such, dead pixels aren’t an uncommon thing. Apparently, some degree of dead pixels is to be expected. Still if you have a lot of them, it would be classified as a defective screen. So, how do you determine if you have dead pixels?

Before we go there, make sure it’s not just dust. Clean your screen first. The best way to do that is to use a soft cotton cloth - no rags or paper towel as they can scratch your screen easily. Moisten the cloth with plain old water and wipe the screen gently.

Side note: I’ve also tried maintaining my screen dust free with a Swiffer Duster. These are inexpensive, very soft and they pick up the dirt not just re-distribute it. It has worked well. Of course, this will not take care of smudges or dried on dirt. So you’ll still have to use the cotton cloth and water combo sometimes.

Once you’ve cleaned it, you can run a quick check with a free software called Dead Pixel Buddy. It’s basically a very simple file that will rotate your screen through all the basic colors. This way you can tell if a pixel on your screen is not displaying properly. One tip, you might want to get a help of a friend. Two sets of eyes are better than one especially since pixels tend to be miniscule.

You can also do a low tech way by changing your desktop’s background color to black, white, red, green blue and yellow, checking the screen each time you change the colors. This is of course not fool proof especially if you have tons of icons on your desktop but it’s a good ‘backup’ check if you don’t have Internet access to download the file or whatever the case may be.

If you do find dead pixels, don’t panic yet, as mentioned earlier, a small amount of dead pixels could be inevitable but if you have a lot of them and your notebook computer is still under warranty, this may be a good time to call up the manufacturer and ask for assistance.
