Spycams don't get much better than the Digital Window. Unlike most spycams, which show just one angle with grainy quality, the Digital Window shows a full 180-degree panorama in full high-definition.
Of course, shooting that much footage at once means this thing fills up a lot of data, and fast. The device uses 5 cell phone camera lenses that automatically stitch their pictures together, resulting in an output of 100 megapixels per second. Yeah, that'll fill your hard drive up fast. But if you just need to get the complete view of your office at all times to make sure no one is sneaking up on you, you really can't do much better than this.
