DNS-722-4 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.

Instant Live View
D-Links 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-Links 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 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).

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, Backup and File Manager, and Multi-NVR Viewer. The Multi-NVR Viewer supports simultaneous display of up to 16 channels. The Playback Manager includes a clean and simple web GUI interface that allows users to play and 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.
