"The patrol bots aren't going to attack," she explained, circling bits of the design with her finger. "They'll have a camera attached and constant video footage. They'll divvy up the island with separate paths, and they'll have GPS trackers. There will be a spot somewhere with one monitor per droid, and a quick map of where each droid is. They'll send out a minor alarm when something in their range signals violence: just enough that whoever's nearby can peek at the monitors and see what's up, not enough to worry anybody if it's just two squirrels getting into a fight. If the trooper station has someone around all hours, then they can peek at the monitors whenever something there beeps. If it's nothing, they hit a button and let the droid know to go back to patrolling. If it's not nothing, then we've got a good look at it and we know exactly where it is, and who needs back-up in a big hurry."
