Interval 
The interval for sending ranges from 0 to 3600 seconds. 0 means that 
there is no interval. 
Note: The system will not send an email immediately when the alarm 
occurs. When an alarm, motion detection, or video abnormality triggers 
an email, the system sends out the email according to the interval that 
is specified here. This function is very useful when there are too many 
emails activated by events, which might result in an overload for the 
email server.

NVR sends out emails to test the network connection. 
Email Test 
Click Test to send a test email. A popup message appears to indicate 
the state of the network connection.
