Here’s an idea.
I’d like to have a wireless or blue tooth microphone that is linked to a small speaker which can be mounted on a wall or to an electrical outlet.
Next, the idea would be to take several of these and set them up so that the mic is outside the house and the speaker is under the nearest windowsill.
When they are all switched on, I could hear all the sounds from outside at the windows of my house. If the volume was high enough. I could hear the sounds from all angles.
