D-Link DNS-722-4/DNS-726-4 User Manual

Section 1 - Product Overview

DNS-722-4/DNS-726-4 is a standalone wired NVR (Network Video Recorder) which supports multi-channel network

cameras with M-JPEG, MPEG4, H.264 recording using two high-speed 3.5-inch SATA hard disks (up to 3TB total

capacity for extended recording). The NVR can record video directly sent from local and remote network cameras

without the need for a dedicated PC.

DNS-722-4 supports D-Link network cameras only.

DNS-726-4 supports D-Link, Axis, Panasonic, Sony, Mobotix, Arecont, IQinvision, Cisco and ACTi network cameras.

The bundled 16-channel (DNS-726-4 only) recording software can connect to multiple NVRs and manage them as a

group. The DViewCam NVR software provides a total solution for high quality remote monitoring with reliable network

functionality.

Features

Comprehensive IP Surveillance Solution

•

Total Solution:

The D-Link NVR is a standalone SATA RAID network video recorder capable of 24/7 recording

without a PC. The NVR can manage multiple network cameras, providing direct access to view live video

and play recorded data through the Internet from anywhere anytime. The device itself is compact in size and

incorporates a physical security lock.

•

Easy to Use:

A user-friendly GUI simplifies network and camera setup, allowing users to easily access multiple

cameras for viewing, recording, playback, and configuration.

•

Centralized Interface for Configuration:

NVR provides a flexible and economic alternative to manage and

configure multiple IP cameras on a centralized web interface.

•

Megapixel Resolution Support:

The major advantage of digital over analog video is its higher resolution

support. The NVR supports high resolution megapixel recording for vivid video with high clarity.

Complete Network Functionality

•

PPPoE Support:

The D-Link NVR utilizes ADSL services. It can connect to the Internet via an ADSL modem

over Ethernet.

•

DDNS Support:

Dynamic DNS is a solution for users without a fixed IP address. With DDNS service, users

can connect to the NVR from the Internet using an easy-to-remember domain name.

•

NTP Support:

Maintaining an accurate record of time is essential if recorded data is to be used as evidence.

To ensure that the time recording is always accurate, the NVR can update the system clock from an Internet

server using the Network Time Protocol (NTP).

•

DHCP Client:

The NVR can acquire an IP address from a DHCP server, making it easy to locate during

installation.

Fully Functional Recording

1.

Flexible Recording Schedule:

Once cameras have been set up, a highly configurable scheduling system

allows for continuous recording or recording during specifically allotted time frames. Each camera can be set

to record independently at preset intervals. The NVR also provides event recording based on specific triggers.

2.

Recording Automatic Overwrite:

The NVR can be configured to overwrite the oldest data automatically

when Hard Disk 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 Hard Disk 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.

3.

Recording Stop Alert:

The NVR also provides the option to stop recording when the Hard Disk 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.

Comprehensive Data and Hardware Security

1.

Secure Data:

RAID 1 duplicates the recordings database onto two separate drives. In the event of an Hard

Disk failure, data integrity is maintained on the secondary Hard Disk.

2.

Auto Boot after Power Recovery:

The NVR will boot up automatically once the power is recovered after a

power outage.

3.

Access List Control:

User can specify safe and blocked IP addresses to filter the external connections; this

feature increases data security.

4.

Physical Security:

NVR enclosure is compact and easy to conceal in a secure remote location. A front panel

lock protects the Hard Disk and a rear panel lock can be used to secure the NVR with a cable.

5.

Multiple User Privilege Control:

Administrators may also choose access privileges for users by specifying

the cameras they may have access to live view, playback, audio, and PTZ functions.

6.

UPS Status Monitor:

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.

7.

Backup Recording Data:

Recorded data is stored in a secure database. This recorded data can be backed

up to additional storage locations periodically or whenever needed.

Powerful Event Management

1.

Camera Status:

The camera status page will show connection, recording, frame rate and bit rate information

of each camera. Meanwhile, the estimated available recording time is also displayed for quick reference.

2.

Flexible Event Management:

Event setup is another key configuration of the NVR. The NVR can monitor all

of the camera triggers from motion detection or digital input interface(only DNS-726-4 support DI/DO). One

of the most powerful functions is notification application. The NVR centrally controls the digital output, E-mail

and recording of all the connected cameras. For example, if camera 1 detects motion, the NVR can trigger

camera 2 to record, camera 3 to output a light.

3.

Event Log:

With the simple event log, the log pages are organized by date for easy look up.

4.

Multiple Mailing Lists:

Administrators can setup multiple contact lists for event notification.

Instant Live View

1.

Full Screen:

Enlarge the display to full screen of live view and recorded video.

2.

Drag and Drop GUI:

With multiple channels enabled, users can change channel by drag and drop.

3.

Camera Name and Status on OSD:

Camera name and recording status are displayed via OSD to aid in

identification.

4.

PTZ/Audio Support:

Users can control pan/tilt/zoom (PTZ) functions from within the interface using the

provided interface buttons or by directly clicking on the video. A single camera may be viewed full-screen with

optional two-way audio.

5.

Preset Point:

Presets from within the interface can be set to instantly restore a previously saved view.

6.

Digital Zoom:

Videos can be enlarged by digital zoom.
