Network video recorder family

D-Link has released a family of internet-based surveillance products - network video recorders (NVRs) - designed with advanced features and compact size to meet the camera monitoring needs of small-to-medium businesses.

The D-Link 2-Bay NVRs record live video from up to four IP-based network cameras. Based on D-Link’s network attached storage (NAS) technology, both NVRs contain two 3.5” SATA hard disk drive bays and support RAID 1 configuration where recordings are duplicated onto two separate drives for backup if required.

The DNS-722-4 2-Bay NVR Basic is designed to work with D-Link network cameras. The more fully featured DNS-726-4 2-Bay NVR Pro works with D-Link’s network cameras as well as a range of Axis, Sony and Panasonic models.

Both NVRs feature a friendly graphical user interface for multiple camera management and direct access for viewing live video or playing back recorded data through the internet from anywhere at anytime. Up to four NVRs, supporting up to 16 attached network cameras, can be centrally managed via the included D-ViewCam NVR software.

The NVRs can monitor all camera triggers from motion detection or digital input interface. The DNS-726-4 can centrally control the digital output, email and recording of all networked cameras. For example, if camera 1 detects motion, the NVR can trigger camera 2 to record, camera 3 to emit light and camera 4 to turn to the preset position. An event log keeps track of log pages by data for easy look-up, and multiple contact lists can be created for event notification.

Both NVRs boast intelligent playback features. With Smart Search users can save time searching through recorded data. The NVR’s intelligent search function quickly retrieves data by finding a selected area on the video and setting the search criteria (motion detected, object missing, focus lost, camera occlusion, etc). The NVR will display the list and play from the event timeframe. With multiple channel playback - after selecting the desired video period - the DNS-726-4 will begin playback and display up to four simultaneous channels. The DNS-722-4 supports one channel.
