Smart video doorbell with two way audio. Connects to home WiFi and can be accessed anywhere in the world on your phone. Notifys you of someone at your door and also if they ring the bell. Can be set up to more than just your phone so you can hear the doorbell on multiple devices. Also has two way audio so you can hear them and speak to them as well. Smart plug works the same way on the same app turn anything on and off with your phone or tablet can even plus a whole power strip in and control multiple items. Great cheep way to protect your home and pretty neat gadgets. I can't use it because I don't have an existing wired doorbell so I got a battery operated one. Never used but I did open it it looks simple to hook up and the plug is just plug in and the app will find it and it's that simple. ALSO CAN BE HOOKED UP TO ALEXA AND GOOGLE ASSISTANT
