There are cameras and then there are video conference cameras. The difference is the quality of the end result.
Ordinary cameras that have upgraded from web cameras to work as video conference cameras may be able to get the front view, but just move a little to the side and see what happens.
With these cameras, you have to virtually sit at 90 degrees opposite them for the person at the other side to be able to see you on their video screens during a video conference. You can have a peek at this website to know more about video conference camera.
Video conference cameras are essentially wide-angle cameras designed to produce high-resolution images. No doubt these cameras come with their personal lighting and the makes but they do produce results you will definitely be proud of.
Their wide angle video conference cameras take in the whole picture even if you are sitting in the corner of the room or are moving around and speaking.
The people at the other end of the conference connection or connections will see and hear you as if you were in the same room as them.
With a good quality video conference camera, you will be able to make eye contact with your video conferencing partners as if they were physically present in the room.
A professional video conference camera is needed if you are using state-of-the-art equipment from one of the giants like Life-size or Tandberg.
However, if you are just conferencing with friends over the internet you will need an ordinary video conference camera that is no more than a webcam.
