5C Operations of the Reich. Brownshirt Surveillance Backdoor (Car Horn+Rooster)

In this video, when I open the backdoor a (recorded) rooster crows as an "alarm" at the same time another uses their car horn also as an alarm.
It shows a group effort in monitoring/harassment and acting as a threat. The town is a railhead but in the middle of the afternoon no freight, no trains are moving before or after the "alert". What is seen here is a standard rather than a coincidence as shown in small collection of videos. It can only be executed with satellite surveillance inside the home. All the more heinous with public access.
