The 2-Bay Professional Network Video Recorder from D-Link is capable of holding 3.5" SATA drives with each bay supporting drive capacities of up to 4TB for a total capacity of 8TB. This video recorder supports IEEE 802.3/u/z standards allowing for Gigabit data transfer speeds via the integrated RJ-45 port. The integrated Auto MDI/MDI-X ensures an uninterrupted flow of data helping to eliminate any interference within the connections. Configuration and management of the drives is simple with "HDD Control & Manage via PC", you can also reformat the disks, and configure them in RAID 0, 1, or JBOD formats.
This Linux based Network Video Recorder supports a variety of cameras including all D-Link IP cameras as well as network cameras from Axis, Panasonic, Sony Mobotix, Arecont Vision, IQinVision, Cisco, and Acti. Along with a variety of compatible cameras, you can store your video in H.264, MPEG-4, and MJPEG formats.
- Instant Line 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, along with frame rate and bit rate information for each camera. The total available recording time for the system is also clearly displayed for each NVR.
- Live Monitoring & Camera Adjustment
- Users are provided with a variety of options for viewing and organizing camera footage on-screen. For a system with multiple channels, users can drag and drop selected cameras to the viewing area. Camera names and recording status are displayed via on-screen display (OSD) to aid in identification. Preset from within the interface can be set to instantly restore a previously saved view. A single camera may be viewed fullscreen 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.
- Recording Functionality
A single-page interface aids configuration including compression, resolution and frame rate for all connected cameras. The NVR records video from up to nine local and remote network cameras. Once cameras have been set up, a highly configurable scheduling system allows for continuous recording or recording during specifically allocated time frames. Each camera can be set to record independently at preset intervals. The NVR also provides even recording based on specific triggers such as when motion is detected.
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). The NVR also provides the option to stop recording when the HD is full. When the disk reaches capacity, a notification can be sent via e-mail or to an external device such as an audible alarm or LED display via a Digital Input/Digital Output (DI/DO) interface only.
- Event Management
- The NVR centrally controls the digital output, e-mail notifications, and recording for all 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 email or output devices. Users can set up multiple contact lists for even notification. A straightforward logging system organizes events by date for easy recall.
- Intelligent Playback
The DNR-326's smart search function makes detecting notable events easier. 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 important events. Search criteria include options such as motion detection, missing or foreign objects, lost focus, or camera occlusion.
After selecting a desired video period for the display, the NVR can instantly begin playback. The DNR-326 supports 4-channel simultaneous playback. Playback speed control allows for up to 16x speed fast forward or fast backward play. The step playback option displays one frame at a time. Additionally, users can enhance the recorded video with controls such as brightness, contrast, and sharpness. During playback, if a user has video that needs to be exported, two formats are available. The AVI and ASF file formats will also overlay a timestamp on the exported video.
If a printer is connected to the user's PC, the NVR can also print a selected still image. The D-Link NVR ensures the security and integrity of IP camera footage. Administrators may filter external connections to the NVR by IP address, limiting access and thus increasing security. The NVR also includes the option to protect data using a RAID 1 configuration. RIAD 1 duplicates the recordings database onto two separate drives. In the event of an HDD failure, data integrity is maintained on the secondary HDD.
