The clever uses for file-syncing utility Dropbox never seem to end. In addition to the many creative uses for Dropbox we've already highlighted, Digital Inspiration explains how to use Dropbox to remotely monitor your computer and catch any unauthorised users.
Setting up Dropbox to monitor your computer can be useful if you want to track the progress of a task or you want to know how your computer is being used while you are away. The idea behind the trick is straightforward: set up your computer to take screenshots of your desktop in regular intervals, and place the screenshots into a synced folder. Once the files are uploaded to the server, the images will be accessible through any Dropbox interface.
You'll need two utilities: a screen capture utility (like Lifehacker favourite Snagit or free utility Screen Grabber) that will save shots to your Dropbox folder and a tool to automate the screenshots. Digital Inspiration offers suggestions for both tools, including an AutoHotkey script for automating your screengrabs. As Amit from Digital Inspriation notes:
When you lock your workstation, the screen capture process is suspended but it resumes automatically as soon as you log in. You can run this tool on your office desktop and lock the workstation – if you find any screenshots in your Dropbox stream the next day, someone else probably used that machine.
