IP cameras serve multiple purposes; they are employed in all modern video networks for surveillance purposes, and to record and store visual data. PoE switch directly to NVR But, this is only possible if Network Video Recorder or NVR is used along with IP cameras.
The NVR has a major role to play in the functioning of IP cameras. But, it cannot be utilized without the Power of Ethernet or PoE. Without PoE, the NVR has no Ethernet ports on the back panel to establish a direct connection with the IP cameras. This is where an external PoE switch comes into the picture. The connection is established between a PoE switch and NVR to operate IP cameras. It means a PoE switch can be directly connected to NVR.
Before we discuss how to set up a PoE switch with NVR, we will talk a bit more about NVR and how it is different from a PoE switch.
About Network Video Recorder
When NVR is integrated with PoE transmission protocols, it’s known as PoE NVR. It offers centralized controls for video or image management and storage. To form a managed Poe NVR network, the NVR technology is integrated with PoE switches.
The connection of PoE and NVR enables the transmission of electronic data and power over an Ethernet Cable. Sometimes, multiple switches are integrated for the increased number of powered devices. It’s because data distribution is performed by PoE switches.
When integrated, the PoE switches deliver video data to a specific IP address under the PoE NVR.
Difference between PoE switches and PoE NVR
NVR is an advanced video signal processing technology, while PoE switches act as an intermediate device. If only PoE switches are utilized in the Ethernet network, they will only allow managed networking and data transmission. On the other hand, PoE NVR benefits by enabling remote IP addresses and controlling video data transmission, processing and storage. This improves the quality of the video transmission network.
By now, you might have understood PoE switches and NVR functions and why connecting them will be beneficial for video networking, especially IP cameras. Next, you should learn to connect them.
How should you configure PoE switches with NVR?
As already mentioned, the PoE switches are configured with NVR for two important purposes. The purposes are to reduce Ethernet video transmission network complexity and get extra numbers of ports for transmission. The configuration is done accordingly so that these two purposes are fulfilled.
Configuration to reduce complexity:
- Start with interconnecting the NVR and PoE routers. Generally, the plug and play connectivity is available between NVR and routers. If it’s not available, you should follow the steps discussed in the product manuals.
- Get one or more PoE switches based on your requirements. You should connect the PoE switch to the LAN port of the PoE router using an Ethernet cable. Next, you should connect a power cable to the power outlet of the PoE switch.
- Next, connect the IP cameras to ports. See the number of ports on the PoE switches before the cameras to them. Typically, 1 to 8 switches are available. Connect cameras to ports properly.
- Last, connect IP cameras and a PoE NVR router. Here, operators often get confused. To operate IP cameras, you cannot skip connecting them to the NVR and router. The IP cameras should be interlinked with the PoE NVR router so that centralized control and video recording are enabled.
The configuration of PoE switches to NVR is complete. Now, turn on the power supply to the PoE router. This will eventually power NVR and PoE switches, allowing transmission regularly as NVR does.
With this configuration, video transmission from multiple IP cameras using a single Ethernet cable takes place, reducing the complexity of the network. The best part is that this configuration doesn’t require any external power sources or power wires.
Configuration to get more ports
- Sometimes, high-configuration switches with multiple ports are more in demand. Such applications or setups have nothing to do with complexity. To add more ports to the networking structure, follow the below-mentioned steps.
- Start with finding a PoE switch that has 1 to 8 ports and connecting IP cameras to it. Connect the selected PoE switch to the local area network or LAN. With this, the PoE switch will work as a hub or a common switch.
- The next step is a bit complicated. First, connect the hub or command port to the PoE router. Then, connect another PoE switch with 1 to 8 ports to the hub switch through an open port. Once you establish this connection, the number of PoE ports will increase to 15. Simply explained, the 7 utility ports of the hub switch and 8 ports of the secondary PoE switch.
- Last, connect the NVR with the PoE router, ensuring all the cameras are interlinked to NVR.
The configuration of PoE switches with NVR is complete. You can turn on the power to start the operations.
What else should you know to connect PoE switches with NVR?
The IP cameras, NVR routers, and PoE switches should be compatible with one another. Other than this, make sure you use quality products to avoid future problems like switch malfunction, network breakdown, etc
