In addition to seeing them, you will also be able to speak with visitors at your front door through your smart phone, even when you’re not at home. Motion detection sensors, when triggered, will send instant alerts to your phone when activity occurs at your doorstep. After you subscribe to August’s video recording service about $5/month, you will be able to record and then access video with the August Doorbell Cam; you can replay video if you happen to miss visitors during the live feed with this optional cloud recording service. This camera connects to wi fi and is compatible with the company’s other smart home devices, such as the smart door lock, as well as other smart home systems. The August Cam also works with Alexa, Google Home, and Apple HomeKIt, making it easy to lock your door with a simple voice command. In other words, the August Cam is particularly useful in a smart home with other smart devices.
