The technology in video surveillance equipment is used in many ways for the advantage of society as a whole. The technology is used to investigate, among other things, the workload amongst pilots and air-traffic controllers, assessment of driver reactions to warning devices at railroad crossings, and studies of the performance of sleep-deprived locomotive engineers, just to name a few. The equipment includes video cameras, digital video recorders, digital video cameras, and CCTV [closed circuit TV] video cameras.

Events such as the 9-11 terrorist attack in the United States of America and the ever present threat of more terror attacks has resulted in video surveillance equipment becoming more popular than any time before.

This equipment and technology is used in various different portions of society including government agencies, security agencies, companies and businesses, schools, and public and private transportation vehicles.

Video surveillance apparatus is also a welcomed technology in places where around the clock human supervision is needed but not viable. As an example, the New York City Transit system [including the subway, tunnel and bridge authorities] uses video surveillance equipment for monitoring below ground traffic and stations.

There are many components to video surveillance equipment technology such as cameras, software, digital image cameras, infrared sensors, monitors and so on.

Surveillance technology has become an invaluable apparatus for business when it is correctly used. It can lessen the liability and workers’ compensation premiums. It can help identify fraudulent insurance claims, and may help in the deterrence and apprehension of dishonest workers and customers. Present-day technology by the way of computer networks and the Internet additionally provides the capability to observe a business concern remotely from home or other locations.

There are many varieties of cameras and digital video recorders made for a variety of applications. Examples of these are entrance and exit cameras, cash register and counter cameras, internal cameras, outdoor cameras, etc. along with digital video recorders [DVRs] and [VCRs] are the main components of a digital video surveillance system.

Prices for the equipment standard for a four camera digital video recording system for a small retail or office type business can cost at least several thousands of dollars plus the cost of labor of installation. As you might expect medium, large and project level businesses will need to spend proportionately more to satisfy their individual security requirements.

Whatever expenses incurred in buying video surveillance equipment merits the effort and expense. This is because this technology not only reduces the cost of security but also helps in curbing crime and vandalism. There are very few companies, which do not use video surveillance equipment for some purpose or the other. Total sales in video surveillance technology are on the increase. They will continue to do so due to the effectiveness and versatility of this technology.

Back in the year 1814, Joseph Nicephore Nicepe used a wooden box camera to develop World’s first photograph/photo. Referring back to the Books of Optics, photography owes much of its development to Camera Obscura which used a pinhole or lens to project an image of the scene outside onto a viewing surface. 

That was much back, time changed and with it technology. Cameras undertook new forms, from huge sizes they changed into pocket sized cameras (I still remember being clicked by that huge flash camera in my granny’s house, phew, it took four people to carry it from one place to another).

Cameras developed not only in size, but also the quality and color range - from black and white to monochromatic to colored ones. Then came the era of digital cameras which were more specific in their work. Generic, these could be classified as personal and professional ones. Professional ones were much in demand a while ago – from parties to weddings to political agendas, these cameras found a better scope than professional ones. These cameras working on the idea of pixels gave better picture quality. Gradually, this technology was transferred to personal cameras, giving them more scope and demand.

Then Camcorders came – little things which made shooting more vibrant, colorful and interesting. These Camcorders capable of taking photos as well as shooting for long hours became favorites of family people. Professionals preferred Video cameras as ever. Then evolved web cameras – favorite of NRIs and corporates, through which they could see their families and clients while being far away.

Today, there is host of them. With Worlds’ biggest Camera companies, giving them the edge technology, these often come up latest technology. Be it Sony, Canon, Olympus, Panasonic, Nikon, Kodak or Fuji…, handy cameras starting at as low prices as Rs 5000/-, can be seen in every market.

Just as cameras became a common thing, so their marketplace. Now, you could shop for cameras not only from shops but also online. With online shopping platforms like HomeShop18, shopping for camera, camcorders, video cameras, and webcams is as easy as the click of mouse. Search, compare, choose and order online…, the best way to shop from the ease of home

Looking for a foolproof way to print money that won’t have you sharing a cell in the federal pen? If so, then get ready to discover how to turn a video into cash!

This newest twist on marketing is called video marketing and it’s all the rage. Now I’m not talking about slapping together some 2-minute amateur YouTube-style video clip, although even that is better than nothing if you want to catch the video fever and ride the silver screen to success.

Just like any other marketing angle, the whole idea of doing the video thing is to make your cash register ring! So if you’re going to dip your toe into video promotions, you might as well dip your whole foot in and invest in a video that’s both well-planned and well-produced. You’ve got to deliver your message quickly and clearly or you’ll lose your audience in a flash.

Tap into the power of your average Joe or Josephine.

What’s the power behind this marketing miracle? Typically it’s the presence of some ordinary, average-looking man or woman touting all the amazing benefits of whatever product or service is being promoted.

The power of the written word is compelling; but when viewers can sit back in the safety of their own homes and watch someone speaking those same words, the message creates a lot more sizzle and gets those buying juices flowing. Doing it right means creating trust in the product as well as in the person delivering the message. And that, in turn, builds the momentum that drives the viewer to the “got to have it” stage that we all know and love. And when that happens, the cash register rings.

People today are hooked on videos, making it the most popular content online, so there’s plenty of reason to ride that wave all the way to the bank. Get a good enough video out there and you could end up having thousands or even millions of viewers by the time everyone forwards it on to their friends and family!

When it’s on video, even the most dry and static products come alive to create an engaging, dramatic and dynamic impact. The costs of production have come way down and given the potential return on that investment, even if you’re using video to capture new leads, it’s a marketing strategy that’s definitely worth looking at!

Hidden Cameras are entering every fabric of our daily lives. Not only are we being watched in banks, department stores and malls, but now even in homes and businesses of all sizes. But if your worried about being caught on a recording with a cheap hidden spy camera don’t ever worry.

When you recognize a cheap hidden camera and do something illegal, the odds are the images will be so fuzzy that you won’t get caught and prosecuted.

The market for Hidden Cameras is booming today and cheap enough for the average consumer to own one and easily install it wherever there is a wall, countertop, kitchen, or any other location in a home or business. People who do not wish to spend large amounts on expensive cameras are buying Hidden Camera ‘knock-offs’ and finding out the hard way they made the wrong choice.

Let me explain why a lot of the hidden cameras people are buying today are junk. Many hidden spy cameras sold use CMOS technology instead of CCD which stands for ‘Charged Coupled Device’. It is analog technology. The CCD camera has a little higher resolution than CMOS. The camera also functions better in low light. A CCD camera may drain a little bit more power than the CMOS cameras but the images are much sharper, easily viewed and of vastly superior quality.

In addition to poor quality most of hidden cameras sold in the market have other limitations over the higher priced ones. Many are big and bulky and hard to conceal. The lenses are not powerful enough to provide good images, and the resulting pictures will turn out to be fuzzy and inferior. Others are unable to zoom-in or out. These are the most likely reasons why these hidden cameras are able to be priced so low.

Many of the Cheap Hidden Cameras are in the market are imitations of the really good hidden spy cameras. They make theirs look just like a good hidden camera and use it to fool the unsuspecting buyer who rarely knows much about a hidden camera. Even trademarks, colors and logos are sometimes copied just like an imitation Rolex wrist watch. All of these marketing tactics are aimed at getting you to buy their hidden camera, and may intimately lead to counterfeiting lawsuits on the seller.

When you search on the Internet for a hidden camera and it is priced low especially if it $100 or less be very suspicious of the quality and be sure to investigate it thoroughly. See if you can check out the product manual and check to make sure it can connect to the output devices like TVs, VCRs, DVD recorders, etc. These cheap hidden camera lenses may also have oily residue on them, which will cause unwanted hues to the pictures. Also, check that the hidden camera can be easily connected and installed easily and in a hidden place.

Business should be even more careful that consumers like you or I because these cheap hidden spy cameras priced at $100 or less are not suited for continuous uses and will break down very quickly costing the owner even more money to replace it with a good one.

Hidden Camera ‘Knock-Offs’ may suit the consumer for to spying on their children, elder parents, nannies and nurses for a short period of time but these hidden video cameras will only last a few months. The old adage still applies even for hidden video spy cameras that you ‘get what you pay for’. So when long term security surveillance is required, we advise to spend the extra money and buy the more expensive hidden video camera system.

“Instant click and shoot capturing all those special memories you wouldn’t want to miss. A convenience that digital technology like modern cameras today provide us. With the various types of cameras we have nowadays, one will surely have a hard time figuring out what kind of camera specifically suits his or her needs. And, of course an important factor to consider, the price. That’s why many of us want to get a hold of those bargain digital cameras available in the market due to the reason that modern cams are actually quite costly.

If you consider yourself a gadget freak, you can be considered as a wise shopper who patiently roams around in all those stores and shopping malls just to get your favorite modern device. Whether it’s the best compact digital camera or the best mini digital camera you are looking for, you’ll surely get it in a price lower than the usual. Especially, taking into consideration that there have been many store out there that offer them in a cheaper price. There are also those online stores that provide promos and discounts. With these factors, you will surely have the kind of digital cam you want for yourself.

However, there are so many things to consider when you are looking for the camera you want to get for your needs. And another essential factors that you need to consider, aside from the price, are the camera features. These definitely matters so that you know what best suits your needs to satisfy how you want you camera to operate. Aside from the weight, size, and resolution, the additional features like multiple shoots, panoramic settings, color switching and many more are certainly important for you to know.

The best digital compact camera, whether branded or not, must possess all these features mentioned above. These are considered as guarantees that you have purchased an up-to-date digital cam. It might not be as expensive similar to those cameras you see in magazines or television, you still have the same camera with parallel features. Camera features truly help a lot in enhancing your photos and make them better than the usual. Even the best digital video cameras have these to give more improvement and quality on the picture or video results.

All you need to do when purchasing a digital cam or a video cam is be a wise buyer at all times. Source out to other stores and malls and even those that you see online to be able to have the best camera you need. Deciding on what to get is surely confusing and surely with all those variations you see in the market more difficulty on what to get adds up. But all these should not be worried anymore if you make a checklist on what specific camera or video camera you want. Write all those features that you want your camera to have or when you are about to buy one, read the labels and the manuals first so that you’ll be sure you’re getting the appropriate one for you. All it takes is extra patience and an ounce of cleverness.”

Your funny bones and hidden video cameras have two things in common. The first is you, the second is humor.

Hidden video cameras have the ugly reputation of being tools for voyeurism and inveterate government meddling. What we fail to realize, however, is that hidden video cameras can be very entertaining, too. They make us snort in amusement or guffaw with wild abandon. How is this possible?

Hidden video cameras are a big thing in the entertainment industry. Reality TV and *** shows utilize hidden video cameras. In fact, these are aimed on just about anyone and anything to record private moments or show outrageous antics.

A Video a Day Keeps Audiences Laughing

Who doesn’t know the shows Big Brother and Just for Laughs? These two are highly rated shows. They have a solid fan base and an ever increasing following. This is impressive because both shows do not rely on celebrity actors to provide the media mileage or the mass appeal. In fact, the two shows feature ordinary people going about mundane tasks.

Big Brother is a classic experiment in social interaction. Carefully screened volunteers are made to live together in one house. This task may seem easy at first; but as the days progress, viewers like yourself will quickly realize just how daunting it is to stay sane inside a fishbowl. Yes, living in Big Brother’s house is akin to living in a fishbowl. There are cameras everywhere, and their presence puts additional strain on housemates. After all, on top of performing tasks from Big Brother, these housemates also have to endure each other’s company for a specified period of time. The show gets interesting as hidden video cameras chronicle what the housemates ate for breakfast and who is slandering whom. Clashes of personalities emerge. People fall in love quickly, and then just as quickly, they fall out. Housemates argue. Some deal with personal issues. Others hold crying sessions or go on journeys of self-discovery. Naturally, all this drama takes place under the watchful lens of hidden video cameras. Viewers can monitor the show’s progress through life video feed from hidden video cameras placed all over the Big Brother house.

Now what about Just for Laughs? Like Big Brother, it is a social experiment and a running commentary on contemporary times. Just for Laughs is a *** show that features ordinary people going about their own business. After being targeted by the show’s actors, they are then engaged in a situation that is sure to raise their eyebrows, if not their voices or their fists. Not surprisingly, Just for Laughs quickly became a very popular show. Footages are usually recorded by hidden video cameras.

Life as a TV Show

The possibility of living under the glare of the lens was explored in depth in the movie, the Truman Show. Jim Carrey plays Truman Burbank. The movie is sad and amusing at the same time. It leaves audiences with the painful reminder that people, even those we call our friends, will not always be moved by our tragedies, whether these are big or small.

Clearly, it pays to have hidden video cameras ready. With one in your home, you can kick your feet up and pretend you’re king of a vacation home in the Spanish Reviera.

Antoine Lindz asked:


HD video cameras are all the rage in the new millennium. Even though prices may be higher than standard definition camcorders, consumers are still buying these cameras from the market. You may wonder what makes an HD video camera different from the rest of the cameras out there. Don’t worry! We’ll get to that soon. First, let’s talk a little about how it all started.

The History of HD Video Cameras

The HDV (High Definition Video) format was developed by JVC, Sony Corporation, Canon Inc. and Sharp Corporation. The huge investors at that time were JVC and Sony. You may say that these four companies were the first companies that offered the consumers HD video cameras. Nowadays, there are other companies that also make HDV hardware products, except Sharp.

The first to release an HDV camcorder was JVC. Their first camcorder was the JVC GR-HD1. It allowed the user to use a standard DV or a HDV using the old 601 color space standard rather than the newer 709 standard. And because of this, and other limitations of the camera, the GR-HD1 did not gain popularity as expected. JVC then shifted their HDV development to shoulder mounted cameras.

On September 2004, Sony was able to release the second HDV camcorder in the market. It was the Sony HDR-FX1 camcorder. Even though it was the second HDV camcorder to be released, it was the first of its kind to gain widespread popularity.

Later, a number of HD video cameras followed. Canon released a number of models in the market that were said to be for both consumers and prosumers. Their popular models are Canon XLH1, XHA1, XHG1, HV10, and HV20.

In 2007, nearly each manufacturer had 1 consumer HD camcorder. The leading manufacturers were Sony, Canon, Panasonic and JVC. Sony is currently in the lead because of its wide selection of models to choose from. Canon, Panasonic and JVC on the other hand may known be in the lead but are manufacturing multiple models for both consumers and professionals. However, the best HDV camcorder for the year 2007 in relation to performance must be awarded to Canon and then followed by Sony. Canon’s HV20 model allowed the manufacturing company to take the top spot in HDV camcorder manufacturing.

Editing Your HDV

Since HDV uses MPEG2 compression to fit HD content onto the same DV or Mini DV tapes, they are somewhat difficult to edit. Splicing HDV for example, will distort the video at splice points because of the interdependencies between groups of video frames.

There’s more. Editing HDV files also forces the computer system to work harder to perform simple tasks of cutting and splicing since the frames in the video do not actually exist as independent cells. So some frames may have to be rebuilt.

But there’s no need to worry since there are advantages to editing HD videos by using a Lossless Intermediate. The result is that the file will increase and you will need a bigger storage for your videos in your hard drive.

Despite its disadvantages and limits, HD Video Cameras are still the most widely used cameras for independent video productions. They can be used for professionals or consumers who are interested in making films, and other non-studio applications like news, and documentaries.

Roberto Sedycias asked:


Camcorders are portable devices for electronically recording video and audio through an in- built recorder unit. They differ from the previous units in which the recording and audio devices were separate. Today, a camcorder is a combination of video camera and a video recorder.

Previously, companies such as Sony, JVC and Kodak, etc. used analog video tapes. Since 1990 the digital tape came into use and three years hence, the storage tapes were being replaced by optical disks, hard disk drives and solid state memory. Camcorders, which do not use magnetic tapes, are called `tape-less` while those using two different media, like HDD and Memory card, are called `Hybrid Camcorders`.

Technological advancement has miniaturized the large cameras on specially mounted trolleys to portable video cameras and recorders for broadcasting images. This transition started in 1982 when JVC and Sony released the first professional camcorders. The Betacam, designed by Sony, slowly gained popularity and became the standard device for both news gathering and video editing. This was followed by Betamax in 1983 - the first consumer camcorder. At this stage, they were bulky and generally rested on the user`s shoulder during recording. Even today most camcorders are designed for right-hand users with very few possessing ambidextrous ergonomics.

Both JVC and Sony started improving the quality of camcorders which led to the development of digital devices in 1990. These had cassettes even smaller than the 8mm media allowing further reduction of size of tape transport assembly. The digital variety further improved the audio and video quality over the best analog camcorders. With the advent of digital models, the market has grown substantially being facilitated further by its price and size reduction. Today a device fits in the palm and is sold at a retail price of less than $150.

Camcorders comprise of three basic components : lens, imager and recorder. The lens solely focuses and gathers light on the imager. The imager is the eye of the camcorder which converts captured images into electrical video signals. The recorder encodes the video signals into storable form. The lens offers professional control of all major optical functions such as aperture, shutter speed and focus, etc. The recorder function is responsible for writing the video signal onto a recording medium (magnetic video tape).

Camcorders are normally classified by their storage device. The highest quality digital format such as Betacam and Mini DV, etc., suffer from little generation loss during recording, dubbing and editing. In analog recordings, noise and bandwidth issues relating to cables, amplifiers and mixers are a problem while in digital connections such problems are minimized.

However archival problems continue to affect both analog and the digital varieties. They are both prone to tape format deterioration over time. This is more acute in the digital recordings where large data base is permanently erased owing to deterioration and restoration is very expensive. One of the advantages in analog devices is that the recording may be usable even after the media, in which the data is stored, suffers deterioration.

Consumer camcorders emphasize the basic qualities such as easy usage, price and portability rather than technical performances. Such units offer a wide range of I/O operation but lack various menu settings, video exposures, gain controls and sound level management. For beginners, basic recording and playback facilities are emphasized. Today a personal computer, with a modest configuration, can perform digital video editing with software available in the market.

Camcorders have a plethora of usage in electronic media ranging from electronic news organizations to TV / current affair production. They are invaluable for initial video footage in locations away from the distribution infrastructure. Events which have scheduled set timings, such as official press conferences, use camcorders extensively. They are also used for covering personal events such as weddings, birthdays and other special family gatherings.

Even in the political arena, camcorder is used to film events which have a bearing on the subject. Protesters from various fields, such as animal rights, tax, anti-globalization, war and police, use camcorders to record and film such events which have wide social and historical ramifications. Even some judicial decisions are based on video footages exposed by such devices. They are also used in low budget films, ad shoots, tv shows and for academic film making, etc.

Steve Cownley asked:


Major Components

All video cameras contain 3 major components - the lens, imager, and recorder. The lens gathers and focuses the light on the imager, which is normally a charge coupled device (CCD) or CMOS sensor IC. Finally, the recorder will encode the video signal into a form that can be stored. Commonly, the optics and imager are known as the camera section.

The optic lens is the first component in the camera section’s light path. The optics normally have one or more the following adjustments:

1. aperture - controls the amount of light

2. zoom - controls the field of view

3. shutter speed - captures continuous motion

In most consumer units, these adjustments are automatically controlled by the video camera’s electronics, normally to maintain constant exposure onto the imager.

The imager is the “eye” of the camera, housing a photo sensitive device or devices. The imager works to convert light into an electronic video signal through an elaborate electronic process. The camera lens projects an image to the imager surface,

exposing the photo sensitive array to the light.

The light exposure is then converted into an electrical charge. Towards the end of the timed exposure, the imager will convert the accumulated charge into a continuous analog voltage at the imager’s output terminals.

The third piece, the recorder, is responsible for writing the video signal to a recording medium, such as magnetic videotape. The recording function involves many steps of signal processing, and historically, the recording process introduced some distortion and noise to the stored video, such that the playback of stored signal may not retain the same detail as the original live feed.

All but the most primitive of video cameras will also need to have a recorder controlling section which will allow you to control the camera. You can also swich the recorder into playback mode for reviewing your recorded footage.

The image you recorded doesn’t need to be limited to what appeared in the view finder. For a documentation of events such as those used by the police, the fields of view will overlay such things as the time and date of the recording along the top and bottom of the image.

As you can probably tell now, a high definition video camera is very complex indeed. There are several other parts involved as well, although the above are the most important. A HD video camera is very complex in build, making it something

that is more than worth the time it takes to create.
