I have these buzzers that alert me when a door opens in my house. They work very well from a 12v supply and are loud enough to be heard at a fairly decent distance. I have three spots where they are placed so I can hear them around the house. I could put another one in the garage. The only problem is that my dogs are afraid of the noise. I hope they soon realize that if someone comes in, this will help them. I just hope I don't have to turn off the buzzer because of dog stress.
