That’s not the scary thing here. Better to future-proof it.

Running presumably unencrypted SNMP over shared lines is sketchy.

Well to be fair a number of traffic lights now have cameras to monitor the intersection as well. Didn't consider that.

It was only 100Mbps service, per the agreement, but yeah... >smile<

They do have cameras at each intersection, as well as networked audio at many (for all the speakers hanging from light poles that blare annoying instrumental covers of old popular songs).

The issue is that legacy copper plant has a finite lifetime. Paper insulated lines are already mostly useless today. If you have to replace infrastructure you may as well select a more robust modern alternative.

Cameras are cheap these days, and with a decent fiber link, just install one for each crossing, feed the live streams back to the pig sty and whoops you suddenly have all you need for a comprehensive monitoring solution to track people. No matter if they're suspects or not.

The shit you saw on NCIS a decade ago and dismissed as "science fiction" is getting ever more to reality.
