Door bell speaker volume

This is a great piece of kit, and I am very pleased with the video quality. The only problem I have is with the low volume of the doorbell push. When the doorbell push is activated the volume of the reply through the tiny speaker is very low and when combined with any traffic background noise it is very difficult to have any conversation with the person inside the house. I have tried all the “fixes” as advised by Eufy to no avail.
Is this general problem with this system, or have I just got a “bad one”?
