If you work in a busy office it’s a good idea to lock your PC whenever you step away from it. Whether it’s to prevent someone from tampering with your work, viewing sensitive documents or most likely, pranking your system. But if you’re the forgetful type the TF2000 Proximity Sensor can automatically lock your system for you, anytime you walk away. It looks like a small webcam you attach to the top of your screen and it uses ultrasound technology to detect your presence or lack thereof.
The included software configuration tool allows you to specify what keystrokes are triggered when you walk away, how long before they’re sent and most importantly, how far away you have to be before it locks you out. The TF2000 also has ‘walk-to’ settings which can be used to start the login process when you get back to your desk. For example under Windows the CTRL+ALT+DEL command would be automatically sent meaning you just have to enter your password to get back to work.
You can find the TF2000 online for about $85.
