Figure 10. Standard and Standalone NVR Examples
Standard NVR
A Standard NVR's record capability is managed by a Portal Server or Standalone NVR. In a
standard NVR installation, the full Portal Server or Standalone NVR application is installed
on one machine and the NVR application is installed on a separate machine. If you need to
add recording capacity, you can add multiple NVRs as necessary. You use the Portal Server or
Standalone NVR application to configure the Standard NVR (see Configuring a Standard
NVR). A standard NVR has these characteristics:
• supports record only.
• records 10 or 40 concurrent streams depending on license.
• is configured with the standard Portal Server Admin Console or the Standalone NVR
Console.
• records from the
Record
button or the
Scheduler
module.
• Supports "batch" recording where one large file is recorded into multiple smaller files.
Standalone NVR
A Standalone NVR manages the record capability of itself and any attached Standard NVRs.
A standalone NVR is typically used in security, surveillance, and monitoring applications or
anywhere where full Portal Server functionality is not required. In a standalone NVR
Note The NVR 40 lets you record any combination of up to 40 MPEG-1, MPEG-2,
MPEG-4, and WM streams at a time. There are however performance limitations
when recording multiple, simultaneous, high-rate MPEG-2 or WM streams. At
MPEG-2 rates up to 5.5MBps or WM rates up to 1.2MBps 40 simultaneous
recordings are supported. At higher rates however the full licensing capacity cannot
be used. For example, when using the
Best Quality
WM template at 4.5MBps, 10
simultaneous records are supported; when using MPEG-2 at 15MBps, 15
simultaneous recordings are supported.
Note When purchasing additional NVRs, VBrick provides a single combined license that
includes recording capacity for all NVRs onsite.
