Good Video!! Always loved Evansville's system, it has good coverage. I wonder if the other Sentry (the one that continues) always does that or if it is a glitch. I tried recording a Whelen Vortex the same day you recorded this but my camcorder died midway and the siren did not go on for long, I guess cause of the high wind.

@TheWeatherGuys Yeah, close to Owensboro. The siren is located on Oak Dr. by a trailer park. It didn't blast for long (like 20 seconds) and I don't remember it doing the usual double activation, but I can't prove that since the camera battery died. It was still a cool experience though.

I think I know why that test seemed so short when I tried to record that Vortex, five months ago. The siren probably got the second activation code but not the first which would also explain the lack of the double activation.

@DSRX100 Where did you try to record? Owensboro?
