A:Answer We added a doorbell camera to our system and are very pleased with how well it works with the overall system. There is a door monitor so when we open the door, we have that sound notification. However, if we do not want to open the door, we can see who is at the doorbell area and can communicate with them. We have average internet speed, nothing advanced, and the system has worked well for us at all times. When we were out of town, it was useful to see when the doorbell was rung and by whom.
