Maybe something like a LoRa network might wind up being more durable and flexible over the long term? If you have a tiny low-energy sensor that only wakes up for a few milliseconds out of every hour and can be powered by something like a little peltier element or turbine or pile-driven geothermal shaft, what's likely to go wrong besides someone stealing it? And with the design worked out, how much would a unit cost, $100 even with a rugged enclosure and special pricing for government jobs? You'd only have to maintain a handful of base stations as opposed to umpteen dozen fiber terminations, and you could freely move sensor nodes or install new ones depending on what you learn or changes to the program. But that said, it sounds like these sensors are A) along an existing infrastructure project like you said and I misunderstood, and B) also need to monitor for intruders which presumably also involves general surveillance. So...yeah, what gives? Well, whatever, it looks cool.
