The range of projectors available in the market can simply confuse anybody tasked with procuring a video projector today. There are so many features and selections available for different needs and specifications. The following discussion will supply can you with sufficient data that can enlighten you on your decision.
Before even going to an electronics dealer, make sure to take note of the seating capacity, the area of the room, the probable position of the projector in relation to the room, the lighting requirements, etc. If there is an existing screen, take note of the size, type, and location. Pick the probable positions for mounting it in order to identify the distance from the screen to the projector and the kind of mounting appliances needed.
Then you have to identify what requirements are needed from the system, whether live video feeds are to be used. The equipment needed for computer or video player connections are different from those that utilize live cameras.
Think about the light output that is required of this projector. The price for these devices have gone down since it first came out so there's no need to hold back on the lighting output. The minimum level adequate is 2000 lumens. This output is already bright enough to illuminate a screen of small to medium size clearly, that is if the ambient lighting can be controlled. When your screen length is 8 ft or less, just dim the lights or draw the window blinds and 2000 to 2500 lumens will be sufficient. Then again, if it is not possible to control the ambient lighting, the minimum light output should start at 3200 lumens depending on the screen area.
Think about the physical measurements of the projector. The portability of the device comes into question if you plan on moving the unit from one room to another such as in a classroom setting or if you plan on bringing the unit with you on the road such as seminar engagements. In these cases, a fairly small unit is required. Look for a unit that weighs not more than ten pounds.
Choose a projector that gives a 5-yr warranty so that replacement of the bulbs will not be a problem.
If you still don't have a screen, you have a selection of four types: a portable screen, a fixed-frame screen, a pull-down screen, or an electric screen.
Consult a video expert to translate all these data into recommendations for a satisfactory system. You can also ask him for alternative proposals if ever the recommended specifications are too high for the budget.

HD Camcorder
Since the emergence of high-definition media, there have been few companies that have stepped up to the plate in relation to recording videos with crystal clear pictures. Sony has done so, and with leading technology in their fields. There are at least ten Sony HD camcorders on the market and they are incredibly expensive. Ranging from around five hundred dollars to fifteen hundred dollars, the cost seems out of this world, but the quality of the video taken could be well worth the price. The cheaper ones do not have as many features as others, but the most popular seems to be the Full HD 240GB HDD Camcorder.
This Sony HD camcorder is light weight and stylish, with a swiveling flip LCD screen to view exactly what the camera lens sees. The LCD screen also has full touch screen features and you can control the camera in this manner. It has manual exposure controls as well as auto-technology, and does not have an independent shutter function. Included in this Sony HD camcorder is a two hundred forty gigabyte hard drive, with an option to add more memory with removable devices. Near the strap of the camcorder are headphone jacks and a flip panel that opens to reveal USB connections and ports for HDMI. This model includes a built in GPS system, provided that you can find a GPS satellite to link up to. Over all, it uses little power and requires a seven volt battery pack.
The pictures, audio and videos that the Sony HD camcorder takes are a cut above the rest. It records at 1920×1080 pixels in high definition glory. It zooms up to one hundred and fifty times the regular picture and still holds its video quality. An Exmore-R sensor provides improved low light capabilities, and helps reduce background noise while shooting video. You must select one of the on-board audio options, such as two channel stereo or 5.1 Channel surround to record audio. Sony still recommends that you purchase an external microphone for the Sony HD camcorder. New, Smile Shutter technology helps you capture as many smiles as you can with one camera.
Despite its popularity, this Sony HD camcorder is the most expensive on the market. It is nearly fifteen hundred dollars at best, but considering all the bells and whistles that comes with it and the quality of the video recorded, it is well worth the purchase if you can afford it. If in the event that you cannot, there are similar models that are much cheaper with less features but that are just as good. Sony has really outdone itself in the field of high definition cameras and the Sony Full HD 240GB HDD Camcorder is no exception.

HDTV Shopping Guide
The problem is that when you hit the stores looking for a HDTV, you will see all kinds of models and styles and may have to rely on the sales personnel to help you choose the perfect HDTV for your home. Instead of taking the advice of a sales person that just wants to make money and may steer you towards the most expensive TV set in the store, you should follow this guide.
The first thing you must consider is the viewing angle. I have had both plasma and LCD TV's in my home and I can tell you from experience, that an LCD will allow you to view from any angle. I can watch all my favorite shows while fixing dinner or sitting in any location in the room whereas with the Plasma the screen was often darkened from various angles making it hard to see what was going on in the crime lab and if Abby was talking to co-workers or even to herself.
The static resolution is also important if you truly want a remarkable HDTV that will allow you to feel like you are present in the movie or even at the ball game. Can you see the fine details? Look at the clothing and faces of those on the screen, you can see the eyelashes or do you see a kind of smear?
Pay close attention to fast movements of the screen. Ask the sales clerk to change the channel if you have to in order to see how clear a sporting event is viewable. As the skier is going down the track, does he look like a blur or can you actually see his legs and arms as he is swooshing down the hill?
What you want with a HDTV is a clear, crisp image that can be seen at all angles without seeing any fuzzy, distorted images, or blurred images.
