This Chamberlain Wireless Home Intercom System gives you the power of communication through walls, with none of that nasty, germ spreading, eye contacting, spit risking human contact stuff. You’ve got a 1000 feet range on this puppy, which means you probably never have to meet another person ever again. Adjust meal times right and you’ll be able to just hang out and fester in the garden shed for ever. Perfect. $119.95.
Unlike lesser models that transmit a signal through a home’s electrical system and cannot reach rooms on different circuits, this unit uses a wireless 900MHz digital spread spectrum signal to transmit clear, uninterrupted sound to every room, up to 1,000′, ensuring that all conversation is private and free of interference from other wireless devices in your house or the surrounding neighborhood.
