Line-Crossing Detection
Add one or more lines that should not be crossed, then if the set line is 
crossed, the camera will send you notications or even sound an alarm. 
You can also set the crossing direction and detection schedule. It is ideal 
for fence detection, property monitoring, and parking areas.
 
Camera Tampering Detection
When the camera view is blocked, it will send you notications or even 
sound an alarm. You can adjust the detection sensitivity. Increased 
sensitivity results in more recordings and notications.
