DNR-326 2-Bay Professional Network Video Recorder (NVR)

should be kept (within the limits of the HDD capacity). For example, if the NVR

has the capacity to store 7 days of recording, using the overwrite option, the

NVR will record the eighth day and delete the rst day. The NVR also provides

the option to stop recording when the HDD is full. When the disk reaches

capacity, a notication can be sent via e-mail or to an external device such as

an audible alarm or LED display via a DI/DO interface only.

Powerful Event Management

The NVR centrally controls the digital output, e-mail notications, 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 notications via e-mail or output devices.

Users can set up multiple contact lists for event notication. 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 eortless. By

selecting a target area on the video and setting search sensitivity, the smart

search will traverse the video database based on specied search criteria to

locate noteworthy 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 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 uncovers video that needs to

be exported, two formats are available. The AVI and ASF le formats will

transpose a timestamp on the exported video. If a printer is connected

to the user’s PC, the NVR can also print the selected still image. The D-Link

NVR ensures the security and integrity of IP camera footage. Administrators

may lter external connections to the NVR by IP address, limiting access and

thus increasing security. Administrators may also choose access privileges

for users by specifying the cameras they may access 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 RAID1 conguration. 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.

D-ViewCam NVR Software

The D-ViewCam NVR software bundled with the D-Link NVR consists of ve

main components: Playback Manager, Backup and File Manager, Verication

Tool, NVR Search, and Multi-NVR Viewer. The Multi-NVR Viewer supports

simultaneous display of up to 128 channels. Easily organize the view by

directly dragging and dropping video onto the display window. Cameras

managed by the NVR can be viewed as individual sites or categorized into

groups. The Playback Manager includes a clean and simple web GUI interface

that allows users to play, search, or export video. The Backup and File Manager

is a exible backup utility that simplies the process of backing up video data

from the NVR to external storage. The Verication Tool veries whether data

created by the system has been tampered with by adding a digital signature

to each recorded video frame. NVR Search allows you to search for NVR

devices in the local area network.
