ABNORMALITY
If the DVR 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.
Disk
Hard drive failure (or removal), disk errors or a full hard drive all can trigger a customizable set of alarms.
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 DVR’s address is manually entered rather
than automatically assigned by the router.
