This is an old megaphone with a siren feature that I wired to an adapter and plugged in to an outlet behind the garage. When I hit record on the camera, I then ran into the house and hit the switch that controls power to the garage, which includes that outlet and the light on the back (which I turned on so you could see the siren)
Are you going to use this with you fire alarm system?
