So I don’t really have anything to compare it for loudness. I mounted it upstairs and when I open my garage door that’s downstairs if I listen I can hear it ok. It has 3 loudness options I believe 95, 100 and then 105 dB. With the siren mounted outside my bedroom in the hallway I think that the alarm on high would wake me up, lol…that’s the hope at least.
It has 10 sounds preloaded but I think there is more I found with the device handler installed. 5 alarm type sounds that wouldn’t be very comfortable if someone range your doorbell. 3 chimes that make “beep” sounds that I actually use for when my doors open and then something like 4-6 musical tones that are like your old fashioned melodies some clocks or doorbells would have.
As far as quality the sound isn’t very good quality. Sometimes there is a crackle or distorted noise on the end but I noticed that every sound is a little different at a different volume.
For your use it could probably be loud enough for a doorbell but there is no “ding ding” sound. For me it covers what I got it for but I wish it was slightly larger to help the quality. Also sometimes it plays the sound more than once but that could be a ST’s error and not the Dome.
I’d rate it 7/10.
