Defocus detection 
The camera can detect image blur caused by defocusing of the lens, triggering a series 
of alarm actions.  
The sensitivity level determines how much blur is tolerated by the camera before 
triggering an alarm. When enabled, the camera regularly checks the level of image 
fuzziness (to allow for variations in light during the day) and then compares the current 
image to that of the reference image to see if there is a difference. A high sensitivity 
level means that there cannot be a large variance between the reference and current 
image.
