What is Sonar Proximity Detection?
This is an ultra-sonic proximity detector
functioning as a USB keyboard. The primary
purpose is for detecting users stepping away
from a computer terminal they have un-locked
(log-in active), and issuing keystrokes to lock or
log-off the session on the computer.
Now when you walk away from your system, you
will benefit from a hands-free means of locking
your computer.
How Does the System Work?
The concept of the pcProx-Sonar is easy to
understand. The unit incorporates a
sophisticated ultrasonic sensor to detect the
presence of the user.
Your computer simply ‘thinks’ that the pcProx-
Sonar is a USB keyboard that is attached to
your system. The device sends programmable
keystrokes to lock your computer when you
leave the workspace. It’s that simple. No more
unattended and unlocked computers. The unit
will lock the system for you…and you can now
do this hands-free!
The objective is to detect two events. The most
important is the detection of you leaving the
defined work zone of your computer. When the
pcProx-Sonar detects that you have left the work
zone, the unit sends the keystrokes necessary
to lock your systems. For example, when
Windows 2000 users leave their workstations,
they would normally hit the CTL-ALT-DEL-Enter
key sequence to lock their systems. With the
pcProx attached, the CTL-ALT-DEL-Enter
keystrokes are automatically sent for the user.
