USB Sonar Presence Detector

Eliminate the security risks from unattended or unlocked computers! Here's an access control system that's advanced enough to know when a user steps away from a machine and automatically lock the system, yet sensitive enough to avoid awkward time-out settings. Keystrokes, delays and distance information is automatically stored in the device. You'll need one Sonar Detector for each computer that you want to safeguard. Helps you meet HIPAA requirements. It's even easy to install… and attaches as a USB keyboard; no software is deployed on client or server and there's no need for IT support or software updates. All configurations are done through a free utility provided to you. Specifications:
