VIVOTEK - Built with Reliability
NOTE:
1. Although the system supports MAC Binding, the system should be able to detect VIVOTEK's
cameras within the network regardless of the presence of a DHCP server. Ideally, cameras
and the NVR should reside in the same subnet. If a camera's IP is changed for some reasons,
the system should be able to detect its new IP.
2. Note on external storage enclosure via the USB 3.0 interface:
2-1. If external USB 3.0 storage is attached, a max. volume size of 16TB is supported (6TB
max. for single disk drives). The NVR supports the connection to a USB3.0 storage with
a maximum of 5 disk drives. The minimum storage size in the external storage is 64GB.
2-2. The external storage must be powered on first before the NVR.
2-3. Hot-swapping is not supported. If the external storage is disconnected, recording will be
continued using the NVR's internal disk drives.
2-4. The storage configuration on the external storage is separately configured, e.g., RAID
configuration. The RAID volume on the external storage appears to the NVR as a single
large disk drive, and you should create a volume from it from the Storage configuration
page.
2-5. If the disk drives in the external storage are not configured into the NVR's storage
volumes, you can use them as the external backup devices. To do so, you should format
disk drives in the external storage in the FAT32 or NTFS format, and export the recorded
video on NVR to these disk drives.
2-6. Limitations:
• When you are exporting video to the disk drives in an external storage, you cannot
select the other disk drives to create a new volume.
• If the disk drives or volumes in the external storage is smaller than 1TB, you cannot
configure them as volumes for the NVR.
• The connection interface to external storage must comply with the USB 3.0
specifications.
2-7. The RAID or volume configuration in the NVR does not extend to include devices in the
external storage.
