Zmodo The Best Smart Doorbell Greet Pro with Beam With WiFi Extender EVER!! The new Zmodo smart doorbell that will make sure you never miss another visitor. When I first got my Smart Doorbell (Greet Pro Doorbell), I waited a couple of days to install it. I was not sure how to set it up or install it, but after contacting the company. They helped me with every step and thankfully with the item you get all the item needed to install it. I took off the old doorbell in minutes and installed this fantastic Smart Doorbell in less than 10 minutes. I had to place it on the molding around my door frame, and honestly, it still looks great. All you must do is to connect the two wires on to the provided screws in the unit and attach it to your wall; it is truly as easy as 1-2-3. Once installed just set up your account if you like choosing your plan or go with the free one, adjust your settings, and let the fun begin. It is like Christmas every day; this thing is so fun and useful. I get to see who comes to my door when no one is home or when my packages are delivered. Also, you can set it up to send you an alert you when someone comes to your Smart Doorbell or if seen in the motion zones. I can even talk to anyone that comes to my house. It has never been that easy to see, hear, and communicate with the people at your front door (or any door) using the Zmodo The Best Smart Doorbell Greet Pro with Beam With WiFi Extender.
