I was on Google Maps and I came across this siren. Any idea what this could be? Link: https://www.google.com/maps/@45.7695385,-99.623595,3a,27y,342.99h,111.64t/data=!3m6!1e1!3m4!1srAHnkzxOT6AqkIqqHvAdlg!2e0!7i13312!8i6656 Looks like a variant of a Sentry to me, especially with that mounting bracket.
