Device Setting -> Alarm -> Exception
41
An Exception is any deviation
from the NVR’s normal behavior
- phrased another way, it’s like
saying the NVR’s been working
fine except for these events.
There are 4 Exception Type:
HDD Full: As the name suggests, this event occurs when the NVR runs out of space on the hard drive to
save new footage. This event is redundant if you’ve got overwrite enabled, as the NVR will automatically
delete old footage to ensure it can continue to record.
HDD Error: Occurs when the NVR has trouble accessing its hard drives, or when it cannot detect one at
all. This error could be generated by either an internal hard drive, or an external one connected to the
eSATA port.
Net Disconnected: Will occur if the NVR has problems connecting to the Internet. This may indicate a
problem with the NVR’s configuration, a fault with your network or a problem with your Internet Service
Provider (ISP).
IP Conflict: This event will occur if the NVR detects another device on the same network with a
conflicting IP address.
After above Exception type alarm happen, you may create any combination of the Audio Warning,
Send Email or show exception for the alarm action.
Audio Warning: The NVR will use its internal buzzer to emit an alarm tone.
Send Email: The NVR will send an auto-email alert when the event type you’ve selected occurs.
Show Exception: The NVR will display the ERROR icon at the bottom right corner of the live
view screen when the event type that you’ve selected occurs. Click on the icon to access the Event
Log and know more about the exception that occurred.
