'Lectronic remote-signalling motion sensors are getting cheaper than a Super-size with Cheez-wiz (and oblig Personal-meal defibrillator kit) though. Ditto: "X-10" controlled floodlights and any other AC-gadgetry, operable via any AC outlet in the house.

One Really does Not wish to peer out at one's small backyard oasis of greenery ... and see biped eyeballs peering back.
