Is it possible to have the webcam take a picture if my computer is woken from sleep mode?

I have seen that there are some programs with motion detection, but I would prefer a method that takes a picture when the machine is clicked or key pressed.

Platform: Windows 7 Ultimate 64-bit on an Acer Aspire 5755g.

Any possible answers to this would probably be platform-specific. I suggest you mention which platform you are interested in. –  Celada Jul 4 '13 at 1:09

If you are using Windows OS, you can create a Task in Task Scheduler that when a user Un-Locked his account (Also when logged in) it capture the webcam.

Required :
A) a small command line Webcam Capture utility.
B) find out what is and how to work with Task Scheduler.

For required A) you can use this utility for taking picture : Nirsoft WebCamImageSave
For required B) You can search Google ! (a bit Fun)


1) Open your Task Scheduler and create a task with trigger : When Workstation Unlock
2) in the Action tab make new action and select start program
3) you can browse that command line utility that you downloaded (nirsoft webcaminagesave for example.)
4) add these Parameters at the end of Nirsoft application path (With a SPACE between program path and parameters) :

/capture /Filename "C:\CapturedImage.jpg"


the full path with parameters will be something like this:

C:\MyFiles\WebCamImageSave.exe /capture /Filename "C:\CapturedImage.jpg"


5) Just save it and restart your computer :)

if you do everything right, it will take pictures from your webcam anytime that anyone logged (and Locked) your account.

Thanks for this. What if I wanted to see who was touching the mouse or keyboard but not knowing the password to actually unlock the machine? –  WillNZ Jul 4 '13 at 3:22
    
You can not do it easily! because windows blocks run the applications at Logon Screen for security reasons. But maybe there is some ways to do that. but i'm sorry because i can not say it for breaking security reasons. a tip: the easiest to do it is breaking Winlogon process. But it NOT RECOMMENDED –  Amirreza Nasiri Jul 4 '13 at 3:34
    
I have marked this as the answer as it seems the best solution for now. –  WillNZ Jul 15 '13 at 23:06
