Anyone else use a Ring Wi-Fi doorbell? This is the first piece of tech I've purchased that works perfectly. It is a doorbell with built in camera, Wi-Fi, motion sensor and an iOS and Android app. Someone rings the bell, and my device alerts me. It also records the motion. The unit is well made, and can run off batteries for up to 6 months, or off hardwired. It also has an optional plugin "chime".

At $199, it is one heck of a pricey doorbell, but I love mine, and it helps me stay connected when I'm on the road.
