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 with frame rate and bit rate information for each camera, along with total available recording time.

Live Monitoring & Camera Adjustment
The D-Link NVR offers 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 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 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 DNS-726-4 also provides event recording based on specific triggers (e.g. motion detection). 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).

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. The DNS-726-4 supports 4 channel simultaneous playback. Playback speed control allows for up to 16x speed fast forward or fast backward play. The recorded video can be enhanced with built-in controls such as brightness, contrast, and sharpness. AVI and ASF formats are available for exporting video.

Comprehensive Data and Hardware Security
The D-Link NVR ensures the security and integrity of IP camera footage. Administrators may apply IP filters and also choose access privileges for users by specifying the cameras they may access to for live view, playback, audio and PTZ functions.

Recorded data is stored in a secure database. This recorded data can be backed up to additional storage locations periodically or whenever needed. The NVR also includes the option to protect data using a RAID 1 configuration. RAID 1 duplicates the recordings database onto two separate drives. In the event of an HDD failure, data integrity is maintained on the secondary HDD.

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. In the event of a power failure without a UPS, the NVR will boot up automatically once power is restored.

Of course, the security of data is irrelevant unless the device itself is protected from theft. For this reason, the sleek NVR enclosure is compact and easy to conceal in a secure remote location. A front panel lock protects the HDD and the NVR chassis can be secured using Kensington lock slot at the rear panel.

D-ViewCam NVR Software
The D-ViewCam NVR software bundled with the D-Link NVR consists of three main components: Playback Manager Pro, Backup and File Manager, and Multi-NVR Viewer. The “Multi-NVR Viewer” supports simultaneous display of up to 16 channels. The “Playback Manager Pro” includes a clean and simple web GUI interface that allows users to play, search or export video. The “Backup and File Manager” is a flexible backup utility that simplifies the process of backing up video data from the NVR to external storage.
