Comprehensive Data and Hardware Security
The D-Link NVR ensures the security and integrity of
IP camera footage. Administrators may filter external
connections to the NVR by IP address, limiting access
and thus increasing security. Administrators may also
choose access privileges for users by specifying the
cameras they may access to for live view, playback,
audio and PTZ functions.
Recorded data is stored in a secure database. This
recorded data can be backed up to additional storage
locations periodically or whenever needed. The NVR
also includes the option to protect data using a RAID 1
configuration. RAID 1 duplicates the recordings database
onto two separate drives. In the event of an HDD failure,
data integrity is maintained on the secondary HDD.
A UPS can be used as emergency power supply for the
NVR. The UPS uses a USB interface to notify the NVR
to perform a proper shutdown before battery power runs
out. In the event of a power failure without a UPS, the
NVR will boot up automatically once power is restored.
Of course, the security of data is irrelevant unless the
device itself is protected from theft. For this reason, the
sleek NVR enclosure is compact and easy to conceal in
a secure remote location. A front panel lock protects the
HDD and a rear panel lock can be used to secure the NVR
with a cable.
Complete Network Functionality
The D-Link NVR takes advantage of existing network
architecture, taking advantage of features such as PPPoE
and ADSL services. The NVR can acquire an IP address
from a DHCP server to become easily searchable during
installation. Dynamic DNS is supported for systems
operating without a fixed IP address. The NVR can then
be reached from the internet using an easy to remember
domain name provided by the DDNS service.
Maintaining an accurate record of time is essential
if recorded data is to be used as evidence. To ensure
that the recorded time is always accurate, the NVR can
update the system clock from an internet server using
the Network Time Protocol (NTP).
D-ViewCam NVR Software
The D-ViewCam NVR software bundled with the D-Link
NVR consists of three main components: Playback
Manager, Backup and File Manager, and Multi-NVR
Viewer. The “Multi-NVR Viewer
1
” supports simultaneous
display of up to 16 channels. Easily organize the view by
directly dragging and dropping video onto the display
window. Cameras managed by the NVR can be viewed
as individual sites or categorized into groups. The
“Playback Manager” includes a clean and simple web
GUI interface that allows users to play, search or export
video. The Backup and File Manager” is a flexible backup
utility that simplifies the process of backing up video data
from the NVR to external storage.

Hard drive(s) not included with the NVR. An
internal SATA drive is required to store video files.
RAID 1 mirroring requires the use of two internal
SATA drives. 3TB capacity when two 1.5TB
3.5” hard disks are installed in your NVR. Disk
capacity may increase pending future advances
in HDD technology.
3
To avoid data incompatibility in RAID 1 operation,
use SATA drives from the same manufacturer.
Formatted drive capacity for RAID 1 operation is
dependant on the drive capacity of the lowest-
sized drive. Older generation SATA drives may be
incompatible. For a list of SATA drives that have
been tested to work with your D-Link NVR, visit
D-Link support web sites.
