I have been using a Ring doorbell for years. This is really good for monitoring your home when you are away, or just seeing who is at your front door to decide whether or not you want to answer it. You can even communicate with people at your front door! This is also very helpful when establishing a neighborhood watch on your block. Highly recommended. For real-time crime and safety alerts in your area, download the Neighbors app. https://download.ring.com/GnMK/5q5gbeM81J
