No software hands-free auto locking presence detector
The plug-n-play pcProx Sonar solves security risks and privacy concerns with unattended computers without requiring additional software or user action. This solution is a presence detector, not a badge reader. When a user steps away from the computer, the product automatically locks the computer. It detects a user’s presence so the computer will not lock until the user physically steps away, avoiding awkward time-out settings.
The Sonar easily attaches to the PC via a USB port and emulates a keyboard device. This operating mode allows the device to send individual keystrokes and delays to be defined by the user. For example, a Windows XP® equipped system would send a sequence such as Windows “GUI” + “L” to lock the computer when the user walks away.
No software is deployed on the client or server. The pcProx Sonar contains configurable flash memory which holds user- definable keystrokes, delays, settings, and trigger distance (2–5ft).
