cameras for viewing, recording, playback, and conguration.
• Centralized Interface for Conguration: NVR provides a exible and economic alternative to manage and
congure 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.
Features
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 xed 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).

installation.
4D-Link DNS-722-4/DNS-726-4 User Manual
Section 1 - Product Overview
Fully Functional Recording
1. Flexible Recording Schedule: Once cameras have been set up, a highly congurable scheduling system
allows for continuous recording or recording during specically allotted time frames. Each camera can be set
to record independently at preset intervals. The NVR also provides event recording based on specic triggers.
2. Recording Automatic Overwrite: The NVR can be congured 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 notication 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 lter 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.
5D-Link DNS-722-4/DNS-726-4 User Manual
Section 1 - Product Overview
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 conguration 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 notication 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 notication.
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
identication.
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.

Section 1 - Product Overview
Intelligent Playback
1. Smart Search: (DNS-726-4 only). 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 specied
search criteria to locate noteworthy events. Search criteria include options such as motion detection, missing
or abandoned object, lost focus or camera occlusion.
2. Multiple Channel Playback: Multiple channels can be selected for playback or monitored live.
3. Quad View: The DNS-726-4 supports 4 channel simultaneous playback and the DNS-722-4 supports 1 channel
playback.
4. AVI/ASF Outputs: During playback, if a user uncovers video that needs to be exported, two formats are
available. The AVI and ASF format will transpose a timestamp on the exported video.
5. Playback Speed Control: Playback speed control allows for up to 16x speed fast forward or reverse play.
The step playback option displays one frame at a time.
6. Video Enhancement: Users can enhance the recorded video with controls such as brightness, contrast, and
sharpness.
7. Print Picture: If a printer is connected to the user’s PC, the NVR can also print the selected still image.
