This WiFi video doorbell is an easy to install system that you can connect to your existing doorbell, allowing you to easily communicate with the person at your door. It’s one of those DIY installations that don’t require a lot of effort to set up, saving you the trouble of hiring a professional to install it in your home. It has an impressive 720p HD video resolution, as well as great night vision that lets you see things clearly even in complete darkness. With the YYGIFT Smart Video WiFi Doorbell’s motion sensor technology, you’ll receive alerts on your phone whenever someone rings the doorbell. You can also easily adjust the sensitivity so you won’t be troubled with false alarms. You can choose to ignore or answer the call, and even take a photo or video clip of your visitor. And thanks to the system’s built in microphone and speaker, you can easily communicate with whoever’s at the door, with impeccable audio quality that makes communication convenient. Additionally, you can integrate the system to an electronic lock and set a 6 digit code to unlock the door. Now, you can even let your visitors in even if you’re upstairs, in the backyard, in the garage, or even out of town!It’s a really good option for homeowners who want an elegant yet sturdy entryway monitoring camera that’s packed with useful features, but is affordable enough to make it a worthy investment. When we signed the Vivint agreement we didn't select the premium service. That service costs an extra $10 per month and covers all of your equipment and the cost of the service calls.
