Last evening (August 24, 2014) my wife and I were watching TV. We have large windows facing west with a large screen TV on the wall in between the two windows. We have Venetian blinds on both windows, I keep mine closed at night so that ‘visitors’ outside can approach without the fear of being seen.
Around 10 p.m. I started hearing what sounded like small pebbles hitting the window. This went on for well over 5 minutes. I hit mute on the TV so my wife could hear better and the sound quit.
It is impossible to use my 3rd gen NV without being seen myself.
This morning on review of the sound recordings nothing unusual was heard.
