Far be it from us to tell you what to do with this 1.3-megapixel infrared USB Qcam with NightVision and 1280x1024 resolution. It includes a microphone to pick up the sounds of those things that go bump in the night. There are three white LEDs underneath that add just a bit of light, and two infrared LEDs that enable the webcam's nightvision capabilities.
By showing you this device, were actually doing you a service—we're thinking it's probably not clearly marked "Nightvision Spycam," so if you see one somewhere and then you end up staying there after dark, be aware of that unseen eye that might be watching you. One thing has us worried about this product: at $35, its video quality must be atrocious, even in the bright light of day.
