D-Link DNR-326 2-Bay Professional Network Video Recorder DNR-326/KIT 사용자 설명서

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 full 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 important and should be protected from theft. 
For this reason, the sleek NVR enclosure is compact and easy to conceal
in a secure remote location. The rear panel features a cover lock that
protects the HDD and a security lock that allows the device to be 
secured with cable.

The D-Link NVR takes advantage of existing network architecture, using
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  accessed  from  the  Internet
using a 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).

The D-ViewCam NVR software bundled with the D-Link NVR consists of
five  main  layback  Manager,  Backup  and  File  Manager, Verification Tool,
NVR Search, and Multi-NVR Viewer. The Multi-NVR Viewer supports
simultaneous  display  of  up  to  128  channels.  Easily  organise  the  view
by directly dragging and dropping video onto the display window. 
Cameras managed by the NVR can be viewed as individual sites or 
categorised 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.  The
Verification Tool  verifies  whether  data  created  by  the  system  has  been
tampered with or not by adding a digital signature to each recorded
video frame. NVR Search allows you to search for NVR devices in the 
local area network.

2-Bay Professional Network Video Recorder (NVR)

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. The rear panel features a cover lock that 

protects the HDD and a security lock that allows the 

device to be secured with cable.

The D-Link NVR takes advantage of existing network 

architecture, using 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 accessed 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).

The D-ViewCam NVR software bundled with the 

D-Link NVR consists of five main components: 

Playback Manager, Backup and File Manager, 

Verification Tool, NVR Search, and Multi-NVR Viewer. 

The Multi-NVR Viewer supports simultaneous display 

of up to 128 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. The Verification Tool verifies whether data 

created by the system has been tampered with by 

adding a digital signature to each recorded video 

frame. NVR Search allows you to search for NVR 

devices in the local area network.

1 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. 6 TB capacity is provided when 

you install two 3 TB 3.5” hard disks in your NVR. Disk capacity 

may increase pending future advances in HDD technology.

2 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.
