All modern video networks utilize IP cameras. The IP cameras are employed for surveillance purposes, to record and store the visual data. To achieve these purposes, network video recorder (NVR) systems are also used. Owing to advanced protocols and functionality, the industry experts advice using NVR to support video networks integrated with IP cameras. You can configure NVR with IP camera. NVR either works with Ethernet or wireless communication protocols. Due to several benefits of Ethernet over Wi-Fi, Power over Ethernet (PoE) technology is preferred to be used with NVR. However, to connect NVR with PoE, one must know what NVR is, what PoE switches are, and how to interconnect both the technologies. This post discusses all these factors along with the difference between PoE NVR and PoE switches and the process of interconnection.

Before beginning the discussion over how to use the PoE switch setup with NVR, let us discuss both elements individually.

PoE Switches Discussed in Brief

The PoE switches are the intermediate devices that are driven by power over Ethernet (PoE) technology. These switches trigger or terminate the data transmission in an Ethernet cable network. PoE is the protocol that enables data transmission via a single Ethernet cable from single or multiple power sourcing equipment (PSE) to powered devices (PD) like the IP cameras. The switches perform the task of triggering or terminating data transmission to specific devices in the Ethernet network. Basically, the switches take data stream input from PSE and deliver it to the PD of specified IP addresses.

What is PoE NVR?

NVR stands for a network video recorder. When it is integrated with PoE transmission protocols, it is referred to as PoE NVR. This PoE NVR offers centralized controls for video or image management and storage. Often the NVR technology is integrated with PoE switches in order to form a managed PoE NVR network. This PoE NVR connection enables the transmission of electronic data and power over an Ethernet cable. Multiple switches are integrated for the number of powered devices, as data distribution is performed by them. The switches deliver video data to a specific IP address under the PoE NVR.

Difference between PoE NVR and PoE Switches

The difference between PoE NVR and PoE switches is that NVR is an advanced video signal processing technology, whereas PoE switches act as intermediate devices. If video transmission over Ethernet only adopts PoE switches in the Ethernet network, it only allows managed networking and data transmission. On the other hand, PoE NVR enables remote IP addresses and controlled video data transmission, processing, and storage, which improves the quality of the video transmission network.
If both the technologies, namely, PoE and NVR are integrated together, they generate a highly efficient video transmission network. Although to serve regular or advanced video transmission over Ethernet and NVR, the PoE switches are configured with NVR in two different ways. These configurations are discussed in detail in the next section.

Configuration Process of PoE Switch Setup with NVR

Generally, the PoE switches are integrated or configured with NVR for the following purposes.

To suffice these two requirements, the two types of configurations are done in the following ways

The following steps are performed for the PoE switch setup with NVR.

Once done, turn on the power supply to the PoE router, which eventually powers NVR and PoE switches and the transmission will follow in a regular manner as NVR does.
This specific configuration of PoE switches with PoE NVR allows video transmission from multiple IP cameras by using a single Ethernet cable, which reduces the complexity of the network. This system requires no external power sources or power wires.

Some applications may demand high configuration switches with multiple ports. If one cannot find a suitable high-density PoE switch, they can add extra ports in PoE NVR and PoE switch configurations in the following way.

In order to accomplish successful PoE switch configuration with NVR, it is important to ensure the compatibility of IP cameras, NVR routers, and PoE switches. Also, it is important to acquire quality products to avoid future problems like switch malfunction, network breakdown, etc. therefore, you must buy products from trusted suppliers like VERSITRON.
