NVR Overview
The Network Video Recorder (NVR) provides a dedicated platform to perform multiple simultaneous recordings of live streams coming from VBrick encoders. The NVR lets you
The NVR is available in two
•Dedicated platform – NVR servers are available on a dedicated hardware platform which eliminates resource contention and guarantees successful recording.
•Software only – NVR servers are available as a
•Redundant storage – both NVR servers offer RAID 5 for storage redundancy as well as dual power supplies.
•Large storage capacity – the NVR 10 provides 720 GB of storage; the NVR 40 provides 1492 GB.
•Load Balancing – Load balancing is used when multiple NVR servers are installed. Rather than recording to a specified server, the system records to a dynamically selected server based on a load balancing algorithm.
•Software Development Kit – VBrick provides an SDK to interface with the Portal Server or the NVR. In a typical security, surveillance, and monitoring applications application (without a complete Portal Server), you can write a custom application that will record streams directly to a standalone NVR.
In a basic Portal Server installation (without an NVR), the standard recording functionality allows a maximum of two concurrent recordings. In order to expand this recording capability, you can purchase a Network Video Recorder to offload recording tasks and improve overall
