  • SightSpeed users are able to have free video calls with each other, often with no lag and high video clarity on a high speed Internet connection.
  • Video Mail messages can be sent to any e-mail address.
  • The SightSpeed software is able to host video conferences with up to four participants.
  • "Phone Out" is the name of the service that allows users to make phone calls to landlines and mobile phones, paying with pre-paid credit. "Phone In" allows SightSpeed users to receive phone calls from regular telephones.

SightSpeed uses a proprietary artificial intelligence algorithm to remove unimportant information from images. It claims to be able to transmit 30 frame/s live video over a typical ADSL connection with little time lag. When this algorithim is combined with a standards based H263 codec, the result is fluid 30 fps video with little to no latency or lag.

SightSpeed's video codec was originally developed at Cornell University's Discover Lab and is based on H263.

SightSpeed's network technology is SIP based.
