This is the ecobee Smart Doorbell Camera: an Alexa & HomeKit compatible doorbell camera with a 175-degree vertical field of view that lets you see your guest clearly day or night. It uses radar sensing technology for more accurate detection. The device is smart enough to detect people and packages while reducing false alarms. It works with the ecobee Smart Thermostat Premium to show a livestream on its screen.
With 2-way audio, you can greet and respond to your visitors from the app. The Smart Doorbell Camera can withstand exposure to snow and wind. It lets you set an activity zone where you want the camera to focus for motion and person detection. With a subscription, you can have notifications with real-time images sent to your smartphone and Apple Watch.[where to get it]
