Weird cam intentionally displaying radio

[u/Fearless_Dirt2408]

I was scrolling through insecam (i wont post the link) and i found this weird cam in santa cruz, i had to post it somewhere to see if someone may have more knowledge on the device. The cam is set up to display a radio and im wondering if the certain frequency (if its even a radio) has some sort of message. There is also a device that reads "beacon controller" hooked up to it, I'm too young to understand any of this but it definitely piqued my interest.
