this is stupid. proposals and bids are done: the contractor already chosen.
the fact is that cheaper nicer looking fence with sensors (or satellite) could work.
BUT ALL PROPOSALS included use of expensive drones, allot of black boxes (unknown cost and requiring power outlets $$$$)
NO REASONABLE BID WAS EVER MADE
contractors didn't want to be reasonable. they only wanted money for nothing in the box (and to get $$$$$$$$$$ for continually upgrading boxes)
when the contract was "price per foot" the sensor-aided people walked out the door
