Instant Live View
D-Link’s intuitive GUI interface simplifies 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
identification. 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 configuration
including compression, resolution and frame rate for all
connected cameras. The NVR records video from up to
8 local and remote IP cameras. A total of 2 NVRs can
be combined and administered with D-Link’s bundled 16
channel management software.
Once cameras have been set up, a highly configurable
scheduling system allows for continuous recording or
recording during specifically allotted timeframes. Each
camera can be set to record independently at preset
intervals. The NVR also provides event recording based
on specific triggers.
The NVR can be configured 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 notification can be sent via e-mail or to an external
device such as an audible alarm or LED display via a DI/
DO interface only.
Powerful Event Management
The NVR centrally controls the digital output, e-mail
notifications 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 notifications
via e-mail or output devices. Users can set up multiple
contact lists for event notification. 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 specified 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 and ASF
file formats 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.

The answer to expensive, outmoded, analog CCTV surveillance systems has arrived.
When coupled with D-Link’s high-resolution and feature-rich IP cameras, the Network
Video Recorder (NVR) offers a comprehensive video display, storage, and management
solution. The D-Link NVR provides reliable high-quality remote monitoring functionality at
a fraction of the cost of conventional surveillance systems.
