Radio signal used to trigger Dallas sirens

[@LB2234]

Sirens are triggered in most areas by DTMF codes. The suspected person probably got their hands on those DTMF codes and the radio frequency the DTMF goes out on. My guess is some kind of HAM radio used to send the tones. Just my theory.

The power of radios are just amazingly awesome not only that the people trained to do that will remain anonymous and will not be disclosed how they did it it happened get over it!!!!!!!!!!!

why am I watching this? I’m British…

[@jacash44]

unless they pulled a maintenance check to see if it didn't malfunction. they can't claim it wasn't hacked in this video they admitted the city was going to look into upgrading it. so why don't they pull a maintenance exam on it and if it does pass the up to snuff standards then search into the hacking mystery. this is only a common sense comment...
