When PREDATOR has locked your session, if somebody types some key(s) on your keyboard, or moves the mouse, PREDATOR displays a password dialog with a countdown.
If this person enters invalid passwords, or if the password dialog times out, PREDATOR triggers an alarm.

PREDATOR's Password Dialog
A 20 seconds countdown starts. At this point, you are supposed to insert your flash drive, or to type your password (the one you have defined in the program's Settings) to unlock your session.
If the flash drive has not been inserted after 10 seconds, or if the correct password has not been typed, the PC starts beeping.
If an invalid password has been typed or if the Password Dialog timed out, PREDATOR does the following:
- it plays an audible alarm
- it writes a record in the Log
- it displays the Access Denied screen
Furthermore, PREDATOR will take these actions, if you have configured them:
- Take a picture with the webcam
- Take a picture and send it by email
- Take a picture and upload it to a remote ftp server
- Send a simple email
- Run a custom command
You can configure these actions with the settings form.
All access attempts are recorded in the Log. Later, when you finally unlock your session, PREDATOR will automatically show this log to inform you about this intrusion.
