This should be the year of home automation, as Apple's HomeKit specification starts to take root, and CES had a number of products in that arena. The Ring Video Doorbell is a novel product that can replace a doorbell, using the existing wiring. It lets you see who is at the door and communicate with them thanks to a microphone and speaker, all via the free companion app running on an iOS device. This means you can be thousands of miles away and see when a visitor, delivery person, or intruder approaches your door. It's a great idea and at $199, it's reasonably priced. The Ring can also be operated by battery, so you can add a video doorbell to a gate or just about anywhere, as long as it's within range of your home's Wi-Fi.
