2-Bay Network Video Recorder (NVR), Pro Edition
The answer to expensive, outdated, analog CCTV surveillance systems has arrived. When coupled with D-Link or other compatible network cameras, the SecureCenter™ 2-Bay Network Video Recorder (DNS-726-4) offers a comprehensive video display, storage, and management solution. The DNS-726-4 provides reliable high-quality remote monitoring functionality at a fraction of the cost of conventional surveillance systems.
Instant Live View
The intuitive graphical user interface (GUI) 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. 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 simply drag and drop selected cameras to the viewing area. Camera names and recording status are displayed via OSD to aid in identification. Presets from within the interface can be set to instantly restore a previously saved view. A single camera may be viewed full-screen 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.
Extensive Recording Functionality
A clear single-page interface assists with configuration including compression, resolution and frame rate for all connected cameras. The DNS-726-4 records video from up to 4 local or remote network cameras. A total of four DNS-726-4 can be combined and administered with the bundled D-Link D-ViewCam™ NVR software to view up to 16 cameras. Once the cameras have been set up, a highly configurable scheduling system allows for continuous recording or at specifically allotted timeframes. Each camera can be set to record independently at preset intervals. The DNS-726-4 also provides event recording based on specific triggers. The NVR can be configured to overwrite the oldest data automatically when hard drive 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 hard drive 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. It also provides the option to stop recording when the hard drive is full. When the hard drive reaches capacity, a notification can be sent via e-mail or to an external device such as an audible alarm or LED display via the DI/DO interface.
Powerful Event Management
The DNS-726-4 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 e-mail or output devices. Users can set up multiple contact lists for event notification. A straightforward logging system organizes events by date for easy recall.
Searching through recorded data can be tedious and frustrating. However, the DNS-726-4's Smart Search function makes detecting notable events effortless. By selecting a target area on the video and setting search sensitivity, Smart Search will traverse the video database based on specified search criteria to locate noteworthy events. Search criteria include options such as motion detection, missing or abandoned object, and lost focus or camera occlusion. After selecting a desired video period for display, the NVR can instantly begin playback. The DNS-726-4 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 format will export raw video. The ASF format 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.
Comprehensive Data & Hardware Security
The DNS-726-4 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. Administrators may also assign 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 when needed. The DNS-726-4 also includes the option to protect data using RAID 1 configuration*. RAID 1 duplicates the recordings database onto two separate drives. In the event of a hard drive failure, data integrity is maintained on the secondary hard drive.
A UPS that supports 'smart' signaling over a USB connection can be used as an emergency power supply for the NVR. The UPS uses USB interface to notify the NVR to perform a proper shutdown before battery power runs out. Of course, data security is irrelevant unless the device itself is protected from theft. For this reason, the sleek NVR enclosure is compact and easy to conceal in a secure remote location. A front panel lock protects the hard drive and a rear panel lock can be used to secure the NVR with a cable.
Complete Network Functionality
The DNS-726-4 NVR utilizes existing network architecture, taking advantage of features such as PPPoE and ADSL services. The NVR can acquire an IP address from a DHCP server to become easily searchable during installation. Dynamic DNS is supported for systems operating without a fixed IP address. The NVR can then be reached from the Internet using an easy-to-remember domain name provided by the DDNS service. Maintaining an accurate record of time is essential if recorded data is to be used as evidence. To ensure that the recorded time is always accurate, the NVR can update the system clock from an Internet server using the Network Time Protocol (NTP).
D-ViewCamTM NVR Software
The D-ViewCam™ NVR software bundled with the DNS-726-4 consists of three main components: Multi-NVR Viewer, Playback Manager, and Backup and File Manager. Multi-NVR Viewer supports simultaneous display of up to 16 channels. Easily organize your live view by directly dragging and dropping video onto the viewing area. Cameras managed by the NVR can be viewed as individual sites or categorized into groups. Playback Manager includes a clean and simple web GUI interface that allows users to play, search or export video. Backup and File Manager is a flexible backup utility that simplifies the process of backing up data from the NVR to external storage.
* To avoid data incompatibility in RAID 1 operation, use SATA drives from the same manufacturer. Formatted drive capacity for RAID 1 operation is dependent on the drive capacity of the lowest-sized drive. May not work with older generation SATA drives.
