What is NVR? and their types of NVR?

 

A network video recorder (NVR) is a device that includes software. All videos shot by cameras connected to the network will be gathered and stored by this system. These videos are recorded by NVR onto mass storage devices. It lacks specialized video capture hardware, in contrast to other storage devices, and the software is run on a separate device. NVRs are frequently used with IP video surveillance systems, and they may stream audio and video data over a single cable. Hence ICFix Service provides CCTV training courses in Chennai.

 

Types of Network Video Recorders: Depending on how they are powered, network video recorders (NVR) can be divided into two categories.

 

PoE NVR: PoE NVR has PoE ports and is only able to work with cameras that adhere to the PoE standards. These cameras are connected to the NVR’s PoE port. These recorders don’t need a different adapter. A CAT 5E/6 cable can be used to link the camera to the NVR. This will provide power to the camera and enable data, audio, and video transmission via a single wire.

 

Non-PoE NVR: These NVRs lack ports on the rear panel for attaching the camera. To connect to the network camera, you need a PoE switch or external power supply. The majority of non-PoE NVRs have built-in scan features that can locate the network’s cameras.

 

With or without a Power over Ethernet (PoE) or Non-PoE switch, NVR can be configured. With cameras that support PoE, PoE switches are used. There are no separate power adapters needed for the cameras because they are connected to the NVR’s PoE ports. Models without PoE don’t have any connectors for connecting cameras. They do, however, include an internal scan functionality that can scan cameras connected to the same network. PoE models also employ the scan feature.

 

 

 

You will need a few parts and accessories, including a power cable, an Ethernet cable, SATA cables, security screws, and a power supply cable for hard drive installation, to configure the NVR for the IP camera on the network using a PoE switch. The majority of manufacturers offer technical support for the connection procedure or include an easy-to-follow instruction booklet with the product and its accessories.

 

NVR and digital video recorders (DVR) are extremely similar. While NVR is typically used with IP cameras, DVR is typically used with analog cameras. It functions essentially as an IP camera’s DVR.

 

Ethernet switches for IP surveillance are available in a variety of configurations. A hardware configuration sets the stage for configuration. You can proceed with the hardware configuration as follows:

 

● Connect the Ethernet wire at the rear of the NVR using the one you took from the router. Verify the NVR’s Internet connection.

 

● Ethernet cables should be used to connect IP cameras to PoE NVR. The NVR can easily power the IP cameras because it is PoE technology enabled.

 

● Use a VGA or an HDMI cable to connect the NVR to the TV or monitor. Make sure you connect the TV or monitor using the appropriate input—VGA, HDMI 1, or HDMI 2.

 

When these steps are correctly carried out, connecting an NVR and an IP camera is simple. The next phase in configuration is software setup, which can be completed quickly by adhering to the manufacturer’s instructions.

 

The back panel of an NVR without a PoE switch is devoid of Ethernet ports. Each IP camera is powered by an external power supply or an external PoE switch. Similar to NVR with a PoE switch, hardware configuration is the first step in configuring NVR for an IP camera without a PoE switch.

 

Here’s what to do next:

 

● Use an Ethernet wire to link the router’s LAN port to the external PoE switch. The non-PoE NVR and router should then be connected.

 

● All IP cameras should be connected to the PoE switch’s RJ45 ports using Ethernet cables. The PoE switch will handle video transmission in addition to providing power.

 

● Connect the monitor and NVR with an HDMI or VGA connection. Always choose the appropriate input when creating a connection.

 

Only after users add the cameras to the NVR will recording be made possible. By using the instructions in the user handbook as a guide, this is simple to accomplish.
