I have seen lots of those products out there that are smart doorbells - you can see and talk to the person at the door. I have a spare android tablet with a front facing camera and was wondering if I could use that as a smart doorbell? Is there an app already out there, or could someone help me make an app to just skype me or something? I don t know, but I just thought it would be an interesting idea, as a tablet has all it needs, a camera, wifi, a mic ect and this doorbell is going to be indoors. Please help!
