When overall verification begins the 'Surveillance Monitor' will analyze the capture, and after every 10 seconds it will compute if the level of activity in that period was bellow or above the selected overall limit. In all cases it will:

_ If computed activity was above the overall limit then it will wait for another 10 seconds and continues with overall verification.

_ If computed activity was bellow the overall limit and those were the first 10 seconds of overall verification then it goes back to normal verification and no other action is taken.

_ If computed activity was bellow the overall limit and there has been at least 20 seconds or more of overall verification then it will keep a recorded copy of the activity, and/or send you a notification by e-mail, and/or execute an external program.

The overall level is a level above the sensibility level that intends to warn you only when important activity happens.
