If you stand behind the front door and want to talk to the doorbell there, there may be a feedback, because the doorbell must represent a certain volume. Please try the doorbell in real situation.

  1. Go out of reach – for example, in the garden and let a family member ring the bell. Open the Liveview and say the test sentance: just put it in front of the door or I'll come in 2 minutes
  2. Ask a family member to ring the bell when you are in the office and perform the same test. 
  3. Quality will vary with your internet connection
