One-on-one video conferencing equipment differs from one another. If you plan to get your office, you can decide whether to buy a PC-based system, a portable, a rollabout or an installed system.
Just to give you an idea, a PC-based system can accommodate one or two people, the portable 2-8 is good, the rollabout is three to fifteen, and the installed system can be used by 20 or more participants.
You need to get the right size monitor for everyone to look good on the projected image. Most video conferencing uses a 20 or 35-inch monitor, but since this is still small, many people have the option of obtaining an LCD projector.
If you decide which one to get, then the next thing you have to worry about is the bandwidth because the faster the better, so you can compress audio and video signals and real-time connectivity.
Most video conferencing today uses two ISDN lines, so if you do not want to see any blurry movements, it's best to move between 768k and 1.5 megabytes per second.
Codec is the most important tool for video conferencing. If you are looking for one, make sure that the other versions are compatible with the market. You should also check if your system supports full duplex voice and digital echo cancellation so you can see and hear the other person clearly.
To be successful, multiple monitors and projectors are required. This allows you to see the other party and preview what it is going to show. This will prevent mistakes and make sure everyone is listening to what you have to say.
But some people can only use one monitor instead of two. You just have to make sure that the monitor has a picture in the image so you can see its preview of what's next. In case you speak with more than one party, you must also have a bridging system.
As far as the camera is concerned, you can choose from different types. Multiple cameras can display the different side of the presentation if you need to move or even better to the robot version that will automatically follow you.
The document camera in video conferencing must be considered to be compulsory for people to see the visual aids on their face on the screen.
Finally, you might want to use a phone line, so if you need to make a call, you can do this during the presentation. But if you talk to a lot of people, this can happen through the bypass.
Prices of videoconferencing equipment vary, but prices are now more favorable than 10 years ago. In 2006, there is a significant increase compared to 2005, and this is expected to continue as more people are willing to use such a system.
