@xerob I just have a ptz camera positioned on a pole in my garden. It normally is focussed on a small playground with a mic there. So that if any of my kids falls or something happens there, I would hear from inside. The other mic is near a bird feeder in the corner of the garden. The idea being, if I hear any sound from there, I can reposition the camera to focus on the bird feeder. I will google around y-type splitters! Thansk
