This dome siren is not loud at all. It can be easily connected to a ring alarm system, but in terms of sound it doesn't do more than a panel. It also does not function as a secondary call for door warnings. The siren is loud and your neighbors can hear it." It's not true. If your neighbors aren't within six feet of you and German shepherds, no one outside your home will hear it. In fact, I have it in my den turned it on and my wife upstairs didn't even hear it 3000 feet home the laundry horn got louder I think $35 is fine but it doesn't really add much value to the Ring Alarm system.
