To keep your house safe, you could go the traditional route and have an elaborate security system installed. Or could just grab a Cocoon Home Security Device. This single, simple device aims to protect your entire home by using Subsound technology to sense activity even in other rooms. It learns your normal activity schedules to reduce false alarms, and also adds in a pet-friendly motion detector, a loud siren designed to disorientate intruders, and a wide-angle, night vision-capable HD camera with high-quality microphone to let you check in on things remotely and record evidence if necessary. All with only one wire to plug in: the power cord.
