Xandem's security sensors can see through walls

Imagine a real-life version of Harry Potter's magical Marauder's Map, which showed the location of everyone prowling throughout Hogwarts castle. That's what startup Xandem is building: a new kind of all-seeing motion-detection system that's poised to shake up the security market.
