Some of the more expensive models do fancy things, like tracking (the camera follows you around the room) and have nice zooms, which may be useful, depending on your intended use.
Our hosted version of Web Chat works on O365, Lync 2013 (online / on premise) and Skype for Business (online / on premise) and as long as your company is federated with Enabling Technologies Inc (enablingtechcorp.com), then you can take advantage of this easy to implement Live Chat solution.We've set it up such that the settings are optimized for your benefit, and such that you can even login with your account from our social network. If you do, you can save all your personal settings AND, save all the credits you accumulate (you accumulate credits just for being active in the chat rooms).If you aren't familiar with our social network, you should be!(It's hard to find a webcam without a microphone, actually, but if you're buying a really cheap one, do check!) It's worthwhile going to a large computer store (Comp USA, Compusmart, Future Shop, Best Buy, or whatever's large and near you) to have a look, as they tend to have one of each webcam set up and connected to a computer, so you can compare image quality.Enabling Web Chat utilizes your existing Skype for Business/ Lync client to answer incoming webchat conversations.
