The Screen Keeper is a personal, automated, computer privacy system, which blanks and locks your computer screen when you are away from your system. While most other system systems lock your computer based on the amount of time since the last activity, the Screen Keeper system is based on proximity. Walk away from your system and it will automatically blank the screen and lock out input. Come back and it automatically unlocks and restores your computer screen!
The Screen Keeper system comes with a dongle receiver, which plugs into your computer's USB port. A small, low-power RF transmitter can be attached to your clothing or put into your pocket. Whenever you are within a few meters of your system it will be active and you can use it normally. Whenever, the transmitter moves to 4-9 meters away, your screen is automatically blanked and the system locked to prevent tampering.
The distance at which the system is locked and blanked is adjustable over three ranges (short, middle, long). The software also allows you to let the monitor go into power-saving standby mode whenever you are away for the specified amount of time. The transmitter device will also go into power-saving standby mode whenever you are away for a while. To reset the device, simply turn it off, then back on and it will be ready to activate your system whenever you are within the appropriate range.
The single CR2025 battery in the transmitter device will last about a year, based on a standard 5-days/week, 8-hours/day work schedule. For best results, the receiver dongle should be placed on top of the desk, next to the keyboard, which may require the use of a USB extension cable.
