For the past few weeks when I let the girls outside I have been hearing a sound.
I wish I had posted this sooner, as I now know what it is. But I took a few videos.
These are at night so you may or may not see anything and the motion sensor like comes on to show the yard.
This last one was from Wednesday night. The sound was closer (you do hear a dog walking and panting and the ac unit turning on). Towards the end there is an odd sound that came from the woods. And then I heard the sound and another respond back to it.
