1. Briefing
Although D-Link NVR supports up to 9 channel recording, it seems only suitable for small scale deployment. Actually, DNR-326, the Pro version NVR is bundled with a useful free program – Multi-NVR viewer which can support up to 128 channel monitoring simultaneously on dual screen. Powered by this program with multiple NVR deployment, it can bring a flexible and scalable solution to meet a lot of small to medium scale surveillance projects.
2. What is Multi-NVR Viewer?
DNR-326 is bundled with a software pack, called “D-ViewCamNVR Pro”, it includes several useful tools which can be installed from CD. One of the most important tools is “Multi-NVR Viewer”. It is a Windows program which can support dual-monitor display and each of them displays maximum 64 channel cameras from multiple NVRs, includes DNR-322L and DNR-326. Only DNR-326 bundled with Multi-NVR viewer, therefore if end user need to monitor more than one NVR at the same time, at least one DNR-326 is needed.
3. Multi-NVR Viewer application
NVR records all the video footage in its HDD bays locally. A PC or notebook is mandatory for initial setup for NVR. Afterward, user still can login NVR thru web interface to view the live view or playback of single NVR. The web interface is capable for all required setups and basic operations like split screen, full screen, PTZ and manual recording. But it has limitation of maximum 9 channel physical cameras display when live viewing. In a lot of applications, over 9 channel recording is required or multiple site deployment is necessary, for instance the chain store application or multiple product lines in a factory, thus the multi-NVR viewer is especially designed for this kind of application. To install and run the Multi-NVR viewer on the PC allows end user to monitor multiple NVRs at the same time, they can manage to group the NVRs by physical locations or specified demands. It means the NVR still records up to 9 channels at every site independently, but up to 128 channels can be monitored simultaneously at a central or remote location.
NVR supports user privilege settings by demand which is important for the management of video surveillance. For example, the administrator can only grant selected channels for live view or playback for the user named “Security guard” and not allows this user to do the PTZ operation to avoid view angle tampered. And the user privilege applies to web interface and Multi-NVR Viewer by the login name and password.

Web browser
The web interface is a major portal for NVR, user can simply open the Internet Explorer (IE) browser to login NVR and get all necessary operations thru this interface. Figure below shows it provides the Live View, Playback for video display, the Setup, Maintenance for device setup includes IP cameras, Hard Disk Drive(HDD) , recording schedule and all other general functions, the Status shows the NVR system statics and log.
Multi-NVR Viewer
The first step of running Multi-NVR viewer is to add NVR(s) into the Server or Group list in the General Setting menu. It can add as many NVRs as needed and maximum camera channel support for display on single monitor is 64 while dual monitors is 128. The Multi-NVR viewer is majorly for central monitoring purpose when multiple NVRs are already deployed (no matter what locations or networks they are). It perfectly suitable for applications like security guard centre for a building or factory, regional management for chain stores and so on. Figure below is the Multi-NVR viewer with the software package named “D-ViewCam NVR” shown at the right upper corner.
How many NVR can be connected by Multi-NVR viewer is a frequently asked question, the answer is no limited (by design). The only limitation is the display grid, which is 64 on single monitor and 128 on dual monitors. So user can add 200 NVRs, for example, each NVR has 4 cameras connected, but the maximum display channels is 64 or 128 simultaneous. Those cameras list in each NVR can also be grouped in Multi-NVR Viewer for easier operation and management. As the same example above, if the 200 NVRs are all installed in retail chain store, there is one channel in each store called "Entrance". Then user can create a group named "Entrance" and add this specific camera from each NVR to this group.
5. Think big with the small NVR
As many small scale applications just need cameras under 9 channels. NVR is a perfect match in terms of size, HDD capacity, functionality and price. By this post, it introduces the possibility for larger scale applications with NVR(s). And most important it’s a FREE bundle software with DNR-326 as real benefit to end users who need to monitor multiple NVRs without any additional cost. Utilize this good idea can stimulate the local IP surveillance business by NVR and its powerful features.
