Designed specifically for alarm.com interactive systems and will not work unless you have an active alarm.com system. You will always know who is at the front door with an Alarm.com Doorbell Camera. Now with two options to choose from – our original Wi-Fi Doorbell Camera and our new Slim Line – front door awareness has never been easier! Each Alarm.com Doorbell Camera features a doorbell with an integrated camera, PIR motion sensor, digital microphone, and speaker, enabling you to answer the door and speak to your visitors using two-way audio – all right from your app. You can also record doorbell triggered clips, set motion triggered automation rules and receive real-time alerts.
