Introduction

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.



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 specified 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.

RAID

In this section, you may configure your hard drives by clicking the Set RAID Type and Re-Format button. All data will be lost during this process.

Standard: Creates two separate volumes (or one volume if only one hard drive is present). Each hard drive has its own volume.

JBOD (Linear): Combines both hard drives in a linear fashion which will create one large volume geared towards maximum available space.

RAID 0: Combines both hard drives in a striped fashion which will create one large volume geared towards maximum performance.

RAID 1: Mirrors the hard drives for redundancy. If one hard drive fails, the other still has all of the data.

Replace the failed hard drive and it will re-mirror, restoring maximum data protection.



What is RAID?

RAID, short for Redundant Array of Independent Disks, is a combination of two or more disks with the aim of providing fault tolerance and improving performance. There are several different levels of RAID, with each providing a different method of sharing or distributing data amongst the drives. The NVR supports RAID levels 0 and 1.

RAID 0 RAID 0 provides data striping, which spreads out blocks of data over both drives, but does not provide data redundancy.

RAID 0

Although performance is improved, the lack of fault tolerance means that if one drive fails, all data in the array will be lost.

RAID 1 RAID 1 provides mirroring over both disks, with the same read/write speed of a single disk. A

RAID 1 array can only be as large as its smallest member disk.

Because the data is stored on both disks,

RAID 1 provides fault tolerance and protection, in addition to performance advantages.


RAID 1

Section 4 - Troubleshooting

Troubleshooting

Check the System Status LED

The system status LED reports the condition of the enclosure fan and power supply:

Solid Blue: NVR is functioning normally

Blinking Blue: NVR is shutting down

If your unit is configured to work with a UPS, it will continue to run for a while after a power supply failure.

Check Disk Status LEDs

The disk status LEDs report the condition of the disk drives:

These lights will be solid BLUE when drives are connected but inactive.

The lights will blink when the drives are being accessed, formatted or synchronized.

They will illuminate AMBER if a drive has failed.

Replace a Failed Disk Drive

If a disk drive fails, the Disk Status LED will turn amber. If the disk drive belongs to a RAID Volume, the Volume will go Critical or Offline.

Replace the failed disk drive with a new disk drive of the same or slightly greater capacity. Please make sure you have powered down the unit.

Step 1: Open the unit’s front cover.

Step 2: Pull out the failed disk drive.

Step 3: Install a new disk drive into the slot.

If the failed drive belonged to a RAID Volume, the RAID Volume will begin rebuilding as soon as the new drive is installed. During the rebuild, the Disk Status LED will blink. If the replacement drive is free, i.e. not assigned to a RAID

Volume or as a spare, the Disk Status LED remains dark after you install the new drive.

Check RAID Volume Status

Click the Status -> Device Info tab from the menu.



Respond to a Critical RAID Volume

How the unit responds to a critical RAID Volume depends on the RAID level of your Volume and whether you have a spare drive available:

For RAID 1 Volumes, if a spare drive is available, the RAID Volume will begin rebuilding itself automatically.

For RAID 1 Volumes, when no spare drive is available, you must replace the failed disk drive. The RAID Volume will begin rebuilding itself when you install the new disk drive.

RAID 0 Volumes go offline after a disk drive failure. A RAID 0 volume cannot be rebuilt. All data on the volume will be lost.

Check Enclosure Status

Step 1: Click System/Device Info button from the main menu.

Step 2: If CPU temperature is above specification:

Be sure there is adequate air flow around the device.

Be sure that the ambient temperature is below 35°C (95°F).

Step 3: Check the fan speed.

If the fan speed is below 1800 RPM, contact Technical Support.

If any power status item is out-of-specification, contact Technical Support.

Restore the Default Administrator’s Password

If you forget the password, you can reset the password for “admin” to the default password: <empty>. Press and hold the reset button for 5 seconds until the Power LED flashes three times. The Administrator password will now be blank.

Caution

When you reset or recover your unit, sometimes it will cause data corruption. Backup your recorded data before resetting your unit.



Install ActiveX

If you cannot see the complete page of the system when using Internet Explorer, the ActiveX installation process may not be complete.

Step 1: Click the Live View/Playback button on the top right.

Step 2: The browser will ask whether to install ActiveX.

Step 3: Click the upper bar to begin the installation process.

Step 4: Click the Install button to complete the process.

Upgrade Process When Applying Windows Vista

Windows Vista limits the authority of some users, which cause the system to reject a connection through Windows

Explorer. In this condition, you must change the settings of Vista first.

Step 1: Go to Start -> Control Panel.

Step 2: Select Administrative Tools.

Step 3: Select Local Security Policy/Security Options.

Step 4: Select “Network security: LAN Manager authentication level”.

Step 5: From the drop-down menu, choose “Send LM & HTLM – use NTLMv2 session security if negotiated”.


Cannot Playback When Applying Windows 2000

1. Check whether Windows Media Player is installed.

2. If Media Player is installed, verify that it is version 9 or later.

Cannot Login to the Unit through Internet Explorer

1. Check the settings of your anti-virus software.

2. Adjust the settings of or disable anti-virus software.


Appendix A - Choose a RAID Level

Choose a RAID Level

There are several issues to consider when choosing the RAID level. The following summarizes some advantages, disadvantages and applications for each choice.

RAID 0

Advantage



Implements a striped disk RAID Volume, the data is broken down into blocks and each block is written to a separate disk drive



I/O performance is greatly improved by spreading the I/O load across many channels and drives



No parity calculation overhead is involved

Disadvantage





Not a true RAID because it is not fault tolerant

The failure of just one drive will result in all data in an RAID Volume being lost



Should not be used in mission critical environments

RAID 1

Advantage



Simplest RAID storage subsystem design



Can increase read performance by processing data requests in parallel since the same data resides on two different drives

Disadvantage



Very high disk overhead - uses only 50% of total capacity


Appendix B - Replacing or Adding a new Hard Drive

Replacing or Adding a New Hard Drive

It is recommended that you backup your important files before replacing or adding a new hard drive to the NVR.

Replacing a Hard Drive:

Please make sure the power is off before replacing a hard drive. After you have installed the new drive, turn on the

NVR and then connect to the Web UI. The NVR will prompt you to format the new drive (Standard, RAID 1 mode) or both drives (JBOD, RAID 0 mode).

Adding a New Hard Drive:

The NVR is able to work with one single hard drive under Standard mode. Please make sure the power is off before installing a second hard drive.

After you have installed the new drive, turn on the NVR and then connect to the Web UI. The NVR will prompt you to format the new drive.

Note: Formatting a hard drive will erase the data stored on the hard drive. Please backup important data before formatting a hard drive.

Remark 1: An external SATA drive is required to store or share files. (Not included.)

Remark 2: RAID1 mirroring requires the use of two internal SATA drives. To avoid data incompatibility in RAID 1 operation, use identical SATA drives from the same manufacturer. Formatted drive capacity for RAID 1 operation is dependant on the drive capacity of the lowest-sized drive. Some older generation SATA drives may not be compatible. For a list of SATA drives that have been tested to work with the DNS-722-4/

DNS-726-4, visit the D-Link support web site.
