The advantage of using an NVR with Dual NICs

NVR with Dual NICs

What’s a ‘Dual NIC’?

We have been asked about using an NVR with Dual NICs (Network Interface Cards) and why some NVRs have them. To understand the advantages of a NVR with a Dual NIC, we should first understand exactly what ‘Dual NIC’ means. Essentially, a Dual NIC means that an NVR has (2) Network Interfaces or Ethernet Ports. Most NVR recorders only have one ethernet port for connection to your network. So you may ask, “How do you use Dual Ethernet Ports on an NVR?”

Well, we will get into the advantages, but we want to mention that just because your NVR has a Dual NIC does not mean that you have to use both ports. You can use the NVR just as you would an NVR with one port, by plugging into Port #1. In addition, remember that if you do decide to use both ports (to accomplish one of the advantages below) both NIC ports can NOT be on the same gateway/subnet. This will result in neither port being able to work.

What are the advantages of using a Dual NIC on my NVR?

There are 3 main advantages to using the Dual NIC feature on your NVR. Essentially, they are:

  1. Multi Address
  2. Fault Tolerance
  3. Load Balance

We will explain the benefits below in order to bring some insight as to whether a Dual NIC NVR can be useful in your next application.

Multi Address

First, lets talk about the Multi Address and what that means. Multi Address allows for the implementation of two different gateways, or IPs on your NVR. This would allow your NVR to be on your main network, or port #1, while your IP Cameras are on a separate network, or port#2, using a switch or PoE switch. Let’s say that your IP Camera System consists of 30-40 cameras or more. Using the Multi Address would be especially beneficial since it would allow your cameras to be on a separate network so you don’t have 40 cameras bogging down your main network. Keep in mind, the cameras will be on a separate subnet or gateway, but can be accessed manually over the main network. The two networks must be configured using different gateways in order to work properly and avoid conflicts.

 

Fault Tolerance (Net Fault Tolerance)

A second advantage or benefit of using an NVR with Dual NICs is called Fault Tolerance. Fault Tolerance allows for your NVR’s NICs to be configured in a redundant state. In other words, your NVR can be connected to two different switches on your network, so if one fails, the NVR will automatically pop over to the secondary switch and remain operational. This creates a safeguard or redundancy for your data. Fault Tolerance can be a great benefit for applications that require more redundancy, or when the NVR must remain on the network at all times. In applications that require constant remote monitoring, this feature can offer a great benefit to your client.

Load Balance

That brings us to the third main advantage of using an NVR with Dual NICs, which is Load Balance. You can probably ascertain from the terminology, where we are going with this one. Again, this feature is especially beneficial in large applications with 50 or more IP Cameras. Load Balance allows for both NIC ports to ‘share’ the load of video data on your system. The result is that ‘lagging’ or ‘skipping’ on video from the cameras is greatly reduced. Large Security Camera installations can use a lot of bandwidth and Load Balance can help deal with the challenge. The are a few different options when using a Dual NIC for Load Balance with your IP System. Your specific application will determine the configuration that best meets your requirements.

Universal Block Storage (UBS) incorporated in Uniview NVR’s

UBS Technology from Uniview (Universal Block Storage)

Uniview has been a leader in surveillance technology since IP Cameras were first introduced. Since then, the company has continued to dedicate large resources to developing new technology to serve the surveillance industry. One of UNV’s many innovations is their UBS Technology that is incorporated in their NVR Recorders. UBS, or Universal Block Storage was developed by Uniview to help solve some of the issues presented by modern video data recording requirements, as well as dealing with efficiency.

Uniview UBS

 

What is UBS?

A critical job/feature for video surveillance systems is to ensure the video data recordings keep all necessary information. The current trend in Video Surveillance is to increase the date range for recording and to have enhanced volume. Unfortunately, this can threaten the efficiency and reliability of the data.

To solve this problem, Uniview has developed an innovative technology—Universal Block Storage (UBS) which ensures the safety of data while enhancing efficiency.

Unlike traditional file recording methods (packing video data into common file systems like FAT or NTFS and then writing it to hard disk) the Uniview UBS solution directly divides and maps the video data into a hard disk data block, which forms the minimum data unit onto a hard disk.

Benefits of Universal Block Storage:

Higher I/O Efficiency:
By using UBS technology, a higher writing efficiency can be realized. This is because of the reduction of file packing and the rewriting process, plus the ability to directly write to a hard disk. All this reduces the virtualization as well as the data processing layer.

Secured Data:
In common file systems, data is not secure because the video is packed with a common file format. To remedy this, UBS technology has adopted a private algorithm to do all of the data mapping, thus assuring there is no way to directly view video data from the hard disk.

Data Anti-theft and Accurate Playback Retrieval:
Due to the minimum size of data block and higher I/O efficiency, UBS is able to retrieve recording data which contains less than 1 second of video. The playback retrieval can narrow down to a time scale of less than 1 second. This provides accuracy in finding the exact playback data required.

In a common file recording system, if there is a sudden power outage when the recording is not packed into one complete file, the data will be totally lost from the Flash (which may contain a few seconds of video). Using UBS technology, a sudden power outage will not affect the recording. This is because all the video data has already been mapped and written onto hard disk.
