Doing some online shopping and stumbled upon this. I don't have a Samsung TV but figured that someone that does might find this a good buy. Seems to be the cheapest by far after a quick google search. Essentially this enables a Samsung TV (im assuming needs to be smart tv) make video calls over skype or whatever video application is available on the TV.
Amazing price. I needed one of these until my Samsung was warranty replaced with the next model up. Doubt you'd find cheaper and it's from Myer, so good for warranty support.
