Smart WiFi doorbells are nothing new. We have covered a bunch of them here in the past. They are designed to let you see who is knocking on your door from wherever you are. The Zmodo Smart Doorbell is another doorbell that lets you see and speak to your guests from your smartphone. You can record a message to play for guests when you are not home.
The device features smart motion detection, so it alerts you with a video clip when there is any movement. It is possible to allow multiple users to control and answer the door. The Smart Doorbell offers 720p HD video, two-way audio, night vision, and a weatherproof design. It is compatible with iOS and Android devices.[where to get it]
