Don't know exactly where I should post this but I'm pretty sure it would be fine here . I was walking home right now late a t night and I walked by this persons house and out of no where I heard a click and a really high pitched sound that made my ears ring suddenly came on then I kept walking and what I assume was the end of his house another time that high pitched sound came on . Is this a motion sensor of sorts or am I going nuts? I didn't walk back to see or try it again cuz it creeped me out I was wondering if there was motion sensors like this or is it something else. Thanks for reading.
