Local Alarm
This tab handles input from alarms connected
directly to an alarm port on the back of the NVR,
if your NVR has an alarm block. An illustrated
example of an alarm block is shown in Picture
4-25.
Alarm Alias - You can create an easily identifiable
name for the alarm.
Network Alarm
If you are remotely monitoring your NVR from a
mobile device or computer, you can send an alarm
to the system to alert someone, trigger recording
or even scare off an intruder.
ABNORMALITY
If the NVR experiences an error with its hard disk drive (HDD) or its network connection, it can alert you
to the problem so it can be quickly fixed.
Hard Drive
Hard drive failure (or removal), disk errors or a full drive can all trigger a customizable set of alarms.
Obviously, recording to the drive is not one of the actions that can be performed.
Network
Loss of network connection and local network
conflicts involving IP and MAC addresses will
prevent remote monitoring.
•An IP address conflict typically happens when
the NVR’s address is manually entered rather
than automatically assigned by the router.
