Walls have ears, or so they say. The fear of having a recording device near you without your awareness is very real, especially if more and more devices like the Halloween Howler Recorder are released. This motion-activated device would be way more useful though if it has more than just 10 seconds of audio capacity. This is meant to be more of a prank gadget, allowing you to record a short audio clip through the integrated microphone, using these spooky sounds to startle or scare folks who wander around your home in the middle of the night. Powered by four AA batteries, the Halloween Howler Recorder retails for $19.98.
