There is someone on the forum already done exactly that, you can probably find it in the search, but it wasn't just the hardware. What about the entire user experience? With the Hikvision cube it wasn't all that pleasant. Someone calls the door, I unlock the phone, launch the IP cam app, select the front door camera, find and press tiny button to talk and then press it again to disable the talk and press button to listen only to find out that I miss part of the response... it wasn't all that fun... Perhaps SkyBell takes the pain away from this experience.
