The DNS-722-4 and DNS-726-4 are based on D-Link's proven 2-bay network attached storage (NAS) device technology. The DNS-726-4 NVR Pro version works with D-Link as well as Axis, Sony and Panasonic network cameras.
“Both are standalone serial ATA RAID NVRs that feature a security lock, 24/7 recording with a PC, friendly graphical user interface (GUI) for multiple camera management and direct access for viewing live video or playing back recorded data through the Internet from anywhere at any time”, says Harrison Albert, Regional Sales Director at D-Link Middle East.
One of the most powerful features of the cameras is flexible event management. 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.
