First, we must distinguish between two types of cameras: digital cameras and professional cameras.

If you have a decent camera to use to take pictures of family vacation photos or even pictures of products to display on eBay, then a digital camera I want is for you. It's small, compact and just the right price range for the average man / woman.

If you're in the media, however, a professional photographer or share with photography as a hobby, SLRProfessional cameras are here for you. These are much larger, better quality, but considerably more expensive than your average digital camera on High Street.

What aspect in choosing the right camera for you:

I just differentiated the two main types of camera, but what you want to look out for their needs. The following text may be to understand the right type of camera for you in this situation.

Pixel Resolution:

Pixels are tiny dots on a realitydigital image from the image. In essence, the greater the number of pixels, the better the quality. This is because the camera is able to adapt more details in the picture as far a greater capacity to pixel space. This will also allow you to zoom the image larger pixels of an image without pixel (if the image is magnified to the point that can not be assigned to the pixels in each room so that is out of focus is appropriate). For peoplecameras digital cameras 7MP would be a 4-megapixel size pretty well. But for the professional SLR would be looking at about 10 MP +. Obviously, the more megapixels in a camera, plus expenses.

LCD:

The LCD (Liquid Crystal Display) allows the photographer to his image has been taken to check whether the image should be repeated. It also serves as a viewfinder for the photographer, so do not go through the realViewfinder. For a digital camera, they vary from 1.5 to 2.5 cm, but on a professional SLR them from 2.5 inch screen size increases normally start.

Optical Zoom:

This allows the photographer to zoom allows an object without any loss of image quality. Depending on the amount of zoom you can zoom in more. For a digital camera, optical zoom is on average 3.0 to 5.0 (odd cases of special digital cameras have an optical zoom of 6.0 to 10.0, but in the region350 pounds). Professional SLR range from 6.0 +.

Digital Zoom:

This feature allows the photographer to magnify the center by removing the edges of the image (PC). However, depending on the resolution MP camera, the image may be blurred, so be careful. Digital cameras can easily vary on average from 2.0 to 8.0 and the same order of magnitude for the professional SLR, with the exception of some not exceed 8.0. The higher the better zoom camera.

Audio & movieCapture:

This allows you to record sound and moving images at the same time, exactly the same way a camera does a. Some cameras also contain a device to play the video on TV from the camera allows, can all be seen in better image quality. This is both professional digital SLR.

Image Stabilization:

This feature allows the photographer to still images of something moving very fast as a cheetah. The cameracan freeze the picture in those milliseconds of time to create a clear picture of quality. You can use this function in low light. Both usually have camera that function.

MEMORY:

Cameras or internal memory, memory card slots or both. different cameras have different sizes of internal memory and are capable of various types of memory cards. The types of memory cards are important because they tell you what kind of memory cardneed to expand the existing internal memory. And professional digital SLR cameras contain between 8-96MB of internal memory, but the card is purchased to expand the memory capacity from 16MB-2GB (2048MB).

PRESSURE:

Nowadays you can buy special printers, too dependent on the compatibility of the camera, print photos without connecting to a PC. This is true for digital SLR cameras and Professional.

How web broadcasting works

webcams are those handy little cameras that attach to your PC and send images to a web page that can be viewed by others. This enables you to share daily life events with friends and family in other parts of the country or the world, or to arrange a video-conference with colleagues and maintain long distance relationships of all kinds. Of course the number of ways to use this technology is limited only by your imagination.

But before you buy a webcam, it pays to understand a little about how the technology of broadcasting images over the Internet works. Of course, if you’re a full bottle on this already, you can skip this section and go straight to browsing the options on Myshopping.com.au where you can compare products and suppliers, their specifications and prices.

webcams provide ‘real time’ images of people; places and events that can be viewed ‘live’ on a web page. The broadcasting end has a camera that captures the images, feeds them into a computer to an ISP and out to viewing pages across the Internet. There are two different types of broadcast: streaming images, where the images are a constant stream downloaded in video format; or Java, where the images are captured at fixed time intervals and refreshed on the web pages at a rate fixed by the broadcaster.

The Applications – What are you intending to broadcast, and to whom?

There is a wide range of uses of webcam technology. Some examples include personal ‘Big Brother’ style diaries, sharing of family events, workplace security, video conferencing, virtual tourism, road traffic management, weather watching, event broadcast and a host of others.

Before you make a choice about any webcam equipment, it helps to decide exactly how you want to use the technology, in other words, what you are intending to broadcast. This decision will impact upon the type of camera you use, and how you use it.

A second consideration is, who will be viewing your content? What level of quality is expected? This will help determine the type of camera you use, the software involved and your Internet connection. Of course, your Internet connection may be a limitation on how much you can do.

The requirements for video conferencing are different from the requirements of workplace security, which are different again from the requirements of sharing a family event.

The physical components

There are a number of physical components required to make web cam technology work. At the top of the list is the camera itself. Then, depending on the type of camera you use and the way in which you want to deliver the content to the Internet, you may need to incorporate video capture hardware in your computer. Some software is required to help you process the data, and Internet connection is required and a web page into which the data is fed.

CAMERA CHOICES

Your choice of camera depends somewhat on what you are intending to show. If you need to reach a large public audience yo may want good quality camcorder or megapixel camera that captures high quality images. If it’s just for seeing who’s at your front door or keeping an eye on the kids in their playroom, then it may not need to present high quality images. If you are intending to use it outdoors, it will need to be weather proof and you may need to consider sun and UV protection. Available power supply and any robotic requirements for camera movement and focus are extra considerations.

Dedicated webcams

The most basic webcams connect to a PC using a simple usb connection. A wide range of cameras with accompanying software at a range of prices is available for this type of application. Simply search though Myshopping.com.au to compare prices and specifications. Dedicated webcams are simple to install and easy to use, but come with limitations that affect the quality of the images, such as low number of frames per second (refresh rates) and resolution (pixels per inch).

camcorders and security cameras

Higher quality images and more camera control come from using camcorder and security cameras. To use these devices you will need to add a video capture card to your PC. Once you have that installed however, you can use a wide range of cameras from broadcast cameras to miniature spy cameras. You can include variable lens options, filters for daylight and low light situations, as well as robotic controls for panning and focus adjustments. You can search through Myshopping.com.au for camcorder selections.

Integrated cameras

An integrated camera combines the camera and the optical hardware with a video server, and as such requires no additional software. They can be used in network situations or as stand-alone devices for monitoring progress on a construction project for example.

Megapixel cameras

Network megapixel cameras combine network capability with high quality digital camera technology. These cameras offer excellent quality but this creates large files sizes, therefore they have limited application in constant streaming video. However for interval refreshed archive image collection, they are ideal, providing a constant record and high quality. You can search through Myshopping.com.au for digital camera selections.

SOFTWARE

If you are not using an integrated camera solution, you will need to install an encoding program like Webcaster or MediaCaster to transfer your images to a web page.

At the receiver end, when web surfers browse the internet and wish to view live video on the web for the first time, they will need to download dedicated applications that show the content such as an ActiveX control, Windows Media player, Flash player or the like.

INTERNET CONNECTION

Finally, you need an Internet connection. The hardware you will need may include a modem for dial-up connection, or modem/router for a broadband solution. Naturally the higher the quality you want, or the faster refresh rate you want, the more bandwidth you will need. ADSL (Broadband) is going to offer you the best solution, but keep in mind what your Internet connection when you are making choices of cameras and feeder software.

Webcam applications work well with wireless solutions. Make sure when you are purchasing a camera or network video solution that it is compatible with any wireless system you may be using in a LAN.

Key considerations

The specifications that are variable with webcam applications, and are affected by camera type, web interface and Internet connection, include the number of frames per second and the image resolution.

Frames-per-second is the number of times a still image flashes by in a second to give the appearance of moving pictures. In Australia, the standard television PAL format is at 25 frames per second. A webcam with up to 30 frames per second will show normal video images. But the more frames per second you demand, the more bandwidth, memory and processing power is required.

Resolution is measured the number of pixels per inch. High quality photographs require a high resolution. But the standard for web images is a low 72 dpi. Higher resolution images will not be of any better visual quality, just slower to upload and download.

Use Myshopping.com.au to compare different webcams, camcorders and digital cameras. You can compare the prices and specifications of the different products and brands, and a wide range of reputable vendors.

Ten years ago the only video cameras that were available were the analog type that were so big and bulky that they had to be carted around on a trolley while professionals used them to shoot video for television. camcorders have come a long way, they are smaller, slimmer, user-friendly and have tons of options that are available on many different models. Also with todays’ digital technology comes the digital camcorder, which makes shooting and editing a movie a simple and fun activity for many people.

When buying a camcorder it is important to choose one that fits you. Store counters are filled with a great variety of brands and models each with an array of features and formats. It is important to understand these features when buying a camcorder and buying the right camcorder which fits your purpose and budget.

The following guide to buying a camcorder details these features and will give you the guidance needed to buy the right camcorder the first time.

Camcorder Type: While analog camcorders still exist, digital camcorders are the camcorders of the day. Digital camcorders provide a superb recording quality by recording audio and video digitally without any loss in quality. In fact the quality far outweighs analog in yielding excellent color and clarity with 500 lines of resolution. And while digital camcorders are more expensive than analog, the price difference has shrunk enough in the past couple of years to make it very worthwhile to purchase the digital type.

LCD Screen: Digital camcorders display recorded images by using the fantastic flat LCD screen feature. These screens can be rotated about 290 degrees along the vertical line, and horizontally about 90 degrees. These screens have made digital camcorders very popular with consumers since the recording process becomes so easy and fun when you are able to see what is being recorded on the LCD screen in real time.

When buying a camcorder you want to get an LCD screen that is as large as you can afford. The larger the screen the more you can see what you are recording in real time. Another feature of LCD screens is the viewfinder, which is intended for shooting in bright sunlight and helps to save power. The panel size of LCD screens is presented in inches, generally ranging from 1.8 to 3.5 inches.

Zoom Lens Capability: Camcorders have two types of zoom capabilities, digital and optical, and many camcorders come with both. The digital zoom enlarges images by magnifying the actual pixels. The optical zoom feature actually utilizes the movement of the lens. The focal length is changed and image that passes through the lens is captured with optical zoom. Higher optical zoom ratings give better image quality.

Audio: Very often the audio that is recorded with your camcorder is just as important as the video. Mostly camcorders have the same audio quality. Some problems may occur, such as recording of tape motor noise, no sound at all, noise from hand movement and even times when the camcorder will record the wrong thing. The best thing you can do when buying a camcorder is to look for options, and make sure that the camcorder has a microphone jack to which you can attach an external microphone as opposed to relying on the camcorders internal microphone. An external microphone will be of great benefit at those times when you are recording something like a concert, wedding or graduation speech because the external microphone will allow you adjust the channels to fit with the sound levels you are recording.

CAMCORDER MEDIA FORMATS: There are several media formats available with digital camcorders. When buying a camcorder this feature is very important to look at and choose the right format that fits your needs and budget. This is the feature which determines how the video is recorded and what kind of storage device is used.

DVD Camcorders: Before discussing the actual DVD media camcorders, first let’s take a look at the different types of DVD formats of which there are three: DVD-R, DVD-RW, and DVD-RAM. DVD-R is a recordable DVD format with a write-once only capability. DVD-RW is a recordable DVD but it allows rewrites and so provides unlimited writing to same disk. DVD-RAM – DVD Random Access Memory is a DVD disc, which can be recorded with information, erased, and recorded again. DVD-RAM is considered a highly reliable format, as the discs have built-in error control and a defect management system. Therefore, DVD-RAM is perceived to be better than the other DVD technologies.

There are two versions of DVD camcorders: The first one works with rewritable DVD-RAM discs requiring a DVD player with RAM playback or a PC with a DVD-RAM drive. The second works by using the more popular DVD-RW and DVD-R discs that work with most ordinary DVD players and allow for actual recording of images to the DVD disk. A great feature of this recording format is the ability to edit in-camera and with repeated playbacks the disk doesn’t degrade. Also the DVD camcorders’ LCD displays a list of the recorded scenes for quick, easy searching.

MiniDV Camcorders: This type of camcorder stores recorded data to MiniDV cassettes. The video and sound quality is exceptionally good. The MiniDV camcorders are small, sleek and stylish because of the small size of MiniDV cassettes.

MicroMV Camcorders: MicroMV camcorders use tapes that are much smaller than MiniDV tapes and also use more of compression technology. The Micro MV is compressed much more that the MiniDV and records very high quality video as well as possess the capability of full digital editing. The MicroMV is also very compact, lightweight and ultra small.

Flash Media Camcorders: This formats records images to an internal Flash drive and Flash Memory cards. Flash Memory cards include: SD, Compact Flash, Memory Stick and Memory Stick Duo.

HDD Camcorders: Hard Disk Drive camcorders are compact and record in MPEG-2 video as well as other encoded formats and recorded data is stored to an internal hard disk. The upside of this format is the ability to store huge amounts of video data by using compression. The video is saved to the internal hard disc within the camcorder and then downloaded to a computer and burnt onto to a DVD. The HDD camcorder has no moving parts and so there is less chance of mechanical breakdown.

Digital 8 Camcorders: This format records digital video to Hi-8 videotapes. Digital 8 is a consumer digital videotape format developed by Sony, and introduced in 1999. Digital8 equipment uses the same videocassettes as analog Hi8 equipment, but differs in that the audio/video signal is encoded digitally. Picture quality is fairly good and this format allows playback of analog videotapes recorded on Hi-8 camcorders.

The new standard of High Definition Video Recording: HDV Camcorders – High Definition Video camcorders usually utilize MiniDV tapes or Hard Disk Drives which yields a full 1920×1080 resolution. This resolution provides a superb high-def video picture quality, which looks great on a high definition television. When buying a camcorder with this capability it is important to know that for editing high-def video a computer is required with a fast processor and lots of memory to meet the requirements of video editing software.

Image Stabilization: When buying a camcorder a key feature to consider is built in stabilization. Unless you are shooting video with the camcorder sitting on a tripod, which most home users do not do for everyday shoots, the hand must be stable while holding the camera to avoid image distortion caused by unsteadiness or jerking of the hand. This feature helps to fix these errors caused by jerking of the camera in the hand while shooting.

The stabilization feature comes in two types: Optical and Electronic. Superior to the electronic technique, the Optical Image Stabilization technique is where a part of the lens is moved in the camcorder to compensate for the shake. With the Electronic Image Stabilization technique the camcorders’ internal computer shifts the image electronically in the opposite direction of the shake. This is achieved by slightly zooming in on the image. Poor electronic techniques can cause loss of sharpness or resolution.

Controls and Camcorder Size: When buying a camcorder you do not want to compromise usability for size. While a small camcorder maybe cute and convenient to carry, it is important to make sure that it is also user-friendly. You want to be able to reach and use the controls of a camcorder with ease while recording, if the camcorder is so small that you cannot easily access the control buttons the recording experience will be hindered and it will become a hassle.

Batteries: The battery is also a vital feature to consider when buying a camcorder. Does the camcorder come with a rechargeable battery? How long recording time is available on a fully charged battery? The best option is to purchase a camcorder which has a rechargeable battery. Generally different models of camcorders have different battery capacity which allow for varying amount of recording time on a fully charged battery. The two most common rechargeable batteries are the NiCd and the Lithium Ion. The lithiums are usually preferred because they take a charge quicker, are lighter than others and have a longer life span. Most full charges give a battery 6 hours of life.

In the end, the most important factor to consider when buying a camcorder is your personal use, the features you desire and price. Ratings of brands are available and the list of key features and specifications should be looked at to determine if the brand and model fits your needs and budget.

Digital camcorders are not cheap, in fact they are often thought of as a hefty investment that could range anywhere between $280 to over $2500 retail price. Something to consider is that in today’s world with the Internet providing a stage where millions of sellers and merchants compete for your business it is easy to save significant amounts of money by avoiding retail merchants and purchasing digital camcorders at a discount.
