Is there a doorbell camera provided?

No, there is not a doorbell specific camera included.

Deep Sentinel's most popular package is the 3-camera system. We recommend placing one at your front door. This way, the system captures anyone at the front door, whether they ring the doorbell or not. Cameras have 2-way audio built-in, so both you and the LiveSentinel team can communicate in real-time to whoever may be at the door.
