If my dogs bark at night, I listen to them, they dont bark just to bark. Hunting dogs keep quite for the most part, dogs can be trained easily to not bark unless someone or something is there.
The motion sensor floods are second level, they go off something is there. Usually a deer
but one time, dogs went off, I open deck door and shine a lite, 2 guys run off leaving me with a brand new 5 gallon gas can and some rubber hose
I then put up the motion sensors.
Country living is keeping vigilant, thieves come out and steal the stuff we use around the place. Lawn tractors, tillers mowers etc. So we are always on our toes so to speak. Thieves will come and strip off wire for the copper. I see a city lost its Christmas tree due to this reason.
A good dog can be the best first alarm you have. I also like geese, they will go off and attack
