2-Bay Professional Network Video Recorder

Extensive Recording Functionality

A clear single-page interface aids conguration 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 congurable scheduling system allows for continuous

recordingorrecordingduringspecicallyallocatedtimeframes.Each camera

can be set to record independently at preset intervals. The NVR also provides

eventrecordingbasedonspecictriggerssuchaswhenmotionisdetected.

TheNVR canbecongured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). 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. The NVR also provides the option to stop

recordingwhentheHDDisfull.Whenthediskreachescapacity,anotication

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 organises 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 easier.

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 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 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. The NVR also includes

the option to protect data using a RAID 1 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.
