D-Link 2-Bay Professional Network Video Recorder DNS-726-4 User Manual

SURVEILLANCE

DNS-722-4 / DNS-726-4

Instant Live View

D-Link’s  intuitive  GUI  interface  simplifi es  viewing  live 

and  recorded  video  from  the  NVR.  The  camera  status 

page shows connection and recording status, along with 

frame rate and bit rate information for each camera. Total 

available  recording  time  for  the  system  is  also  clearly 

displayed for each NVR.

Live Monitoring & Camera Adjustment

Users are provided with a variety of options for viewing 

and organizing camera footage on-screen. For a system 

with multiple channels, users can simply drag and drop 

selected  cameras  to  the  viewing  area.  Camera  names 

and  recording  status  is  displayed  via  OSD  to  aid  in 

identifi cation.  Presets  from  within  the  interface  can  be 

set to instantly restore a previously saved view.

A single camera may be viewed full-screen with optional 

two-way  audio.  Users  can  control  pan/tilt/zoom  (PTZ) 

functions  from  within  the  interface  using  the  provided 

interface buttons or by directly clicking on the video.

Extensive Recording Functionality

A clear single-page interface assists with confi guration 

including compression, resolution and frame rate for all 

connected cameras. The NVR records video from up to 

4  local  and  remote  IP  cameras.  A  total  of  4  NVRs  can 

be combined and administered with D-Link’s bundled 16 

channel management software.

Once cameras have been set up, a highly confi gurable 

scheduling  system  allows  for  continuous  recording  or 

recording  during  specifi cally  allotted  timeframes.  Each 

camera  can  be  set  to  record  independently  at  preset 

intervals. The DNS-726-4 also provides event recording 

based on specifi c triggers.

The  NVR  can  be  confi gured  to  overwrite  the  oldest 

data automatically when HDD space runs out, allowing 

for  continuous  and  uninterrupted  recording.  Users  can 

specify the number of days the recording should be kept 

(within the limits of the HDD capacity). For example, if the 

NVR has the capacity to store 7 days of recording, using 

the overwrite option, the NVR will record the 8th day and 

delete the 1st day.

The  NVR  also  provides  the  option  to  stop  recording 

when  the  HDD  is  full.  Should  the  disk  reach  capacity, 

a  notifi cation  can  be  sent  via  e-mail  or  to  an  external  

device such as an audible alarm or LED display via the 

DI/DO interface.

Powerful Event Management

The  NVR  centrally  controls  the  digital  output,  e-mail 

notifi cations  and  recording  for  all  the  connected 

cameras.  Input  triggers  from  camera  motion  detection 

or digital input interfaces can additionally be monitored. 

These events will be logged, with optional notifi cations 

via e-mail or output devices. Users can set up multiple 

contact  lists  for  event  notifi cation.  A  straightforward 

logging system organizes events by date for easy recall.

Intelligent Playback

Searching  through  recorded  data  can  be  tedious  and 

frustrating.  However,  the  NVR’s  smart  search  function 

makes detecting notable events effortless. By selecting 

a target area on the video and setting search sensitivity, 

the smart search will traverse the video database based 

on specifi ed search criteria to locate noteworthy events. 

Search criteria include options such as motion detection, 

missing  or  abandoned  object,  lost  focus  or  camera 

occlusion. (DNS-726-4 only)

After selecting a desired video period for display, the NVR 

can  instantly  begin  playback.  The  DNS-726-4  supports 

4  channel  simultaneous  playback  and  the  DNS-722-4 

supports  1  channel  playback.  Playback  speed  control 

allows for up to 16x speed fast forward or fast backward 

play.  The  step  playback  option  displays  one  frame  at 

a  time.  Additionally,  users  can  enhance  the  recorded 

video  with  controls  such  as  brightness,  contrast,  and 

sharpness.

During playback, if a user uncovers video that needs to 

be exported, two formats are available. The AVI format 

will export raw video. The ASF fi le format will transpose a 

timestamp on the exported video. If a printer is connected 

to the user’s PC, the NVR can also print the selected still 

image.
