Yes, I do have a scanner. I have had one since my parents bought it for me back in 3rd grade to listen to all the stuff going on when there would be an accident up on the highway I live near. Although a scanner won’t do you any good in St. George. They use Nextel cell phones as walkie-talkies to talk to each other. This PD is a big joke.
Have you considered using something like a Verizon or Sprint AirCard to stream video to an actual secure location. Maybe use a tethered cell phone to do so.
Looks like a fun project and I’d love to help work on it with you if you like.
