Dahua NVR Setup (Ultimate Guide)

Dahua NVR Setup (Ultimate Guide)

Dahua NVR Setup: An NVR (Network Video Recorder) is widely used in CCTV systems. It is the heart of the IP system. Dahua NVR system provides centralized controls to easily view, manage and store video. What is the Dahua NVR recorder and what is it used for? How is Dahua NVR setup done for IP cameras with or without a PoE switch? We will answer all these questions in this article.


What is the Dahua NVR and What is it Used for?

The Dahua NVR is a video recording device used for IP cameras in the UK. It is responsible for the communication with the cameras and the constant recording of all data received from the cameras connected via network cable or Wi-Fi. The NVR most often integrates into an IP video surveillance system to receive live images or video streams, and record them digitally on a hard drive, USB key, or other mass storage devices.

  • The Dahua NVR allows you to manage your cameras and configure them. You can view all events from the cameras.
  • The NVR has an intelligent motion detection function for your cameras. You can set alerts in case of motion detection and be notified by email.
  • The NVR allows remote viewing of your cameras. By connecting the box to your internet network, it is possible to configure it to access your images from anywhere.
  • Thanks to PoE technology, the NVR can power IP cameras.

How is Dahua NVR Setup Done? 

There are two types of Dahua NVRs on the market: PoE NVRs and non-PoE NVRs. Dahua NVR setup is easy. Here, we will provide the necessary instructions to configure the NVR of IP cameras, including PoE NVR and non-PoE NVR connections.

Please note that it is important to check the compatibility between the NVR and IP cameras during setup.

  • Make sure that the surveillance cameras you have are compatible with your NVR.
  • Make sure the NVR supports the resolution of the cameras, as not all of them are compatible with 4K security cameras or 12MP cameras. Once the resolution of the camera is higher than the resolution supported by the NVR, users should go to the web interface of the IP camera and lower its resolution.

PoE NVR Setup for IP Cameras

Dahua NVR setup with POE switch: The PoE NVR functions as a Lan switch by creating a closed internal network for IP cameras. The IP cameras will be connected directly to the NVR by a single RJ45 cable that powers and connects the IP camera. This simplifies the installation of a video surveillance system, there are no electrical cables to install. So, a separate power adapter is not necessary. In the event of an internet outage, the video recorder will continue to record video streams from the cameras. Here are the installation steps:

  1. Use an Ethernet cable to connect the router to the PoE NVR. Make sure the NVR has internet access.
  2. Directly connect IP cameras to PoE NVR by Ethernet cables. Thanks to PoE technology, the NVR can power IP cameras.
  3. Connect the NVR to a monitor or TV via a VGA or HDMI cable. Ensure that the monitor or TV is connected using the correct input (e.g., VGA, HDMI 1, HDMI 2, etc.)

If all connections are successful, the NVR will be connected to the IP cameras.


How to Set Up a Non-PoE NVR with a PoE Switch

Dahua NVR Switch Setting: A non-PoE NVR means that it does not have Ethernet ports on its rear panel, so it cannot be connected directly to IP cameras. A PoE switch or power adapter is required to supply power to each IP camera. Follow the steps below to complete the Dahua NVR setup:

  1. Use an Ethernet cable to connect the LAN port of the PoE switch to the router, and connect the non-PoE NVR and the router. Make sure the PoE switch and the NVR are in the same network.
  2. Connect the IP cameras to the RJ45 ports of the PoE switch by Ethernet cables. The PoE switch provides power and video transmission the same as the PoE NVR.
  3. Connect the NVR to a monitor or TV via a VGA or HDMI cable. Make sure the monitor or TV is connected via the correct input (e.g. VGA, HDMI 1, HDMI 2, etc.).
  4. Please note that users need to install the cameras to the NVR to view the cameras and enable recording. To do this, follow the steps in the user manual attached to your NVR.

Dahua NVR Frequently Asked Questions

Does the NVR require internet?

The NVR can work without the internet and still record and stream video. On the other hand, without the Internet, users will not have access to remote recordings. Users will not be able to receive notifications or alerts in case of intrusion, nor save videos to cloud storage.

What is the difference between a DVR and an NVR?

DVRs and NVRs are two types of recording devices used to record and store videos on hard drives. The DVR (Digital Video Recorder) records analog data. It works with analog cameras and allows to compress of the analog stream to finally store it.

A DVR records video from cameras that are connected via coaxial cable. It does not power the cameras. Each camera connection requires a splitter that powers them. Compared to the NVR which works with IP cameras by Ethernet cables, the DVR costs less. The following table provides a comparison of these devices to help you make the right choice.

Basic principlesIt is a device that wirelessly records data from IP cameras.It is an electronic device whose input comes from a direct connection to the analog camera and the video is encoded and processed from the DVR.
CompatibilityCompatible with digital cameras or IP cameras.Compatible with analog cameras.
TechnologyBased on IP technology in ethernet cabling. It is used to connect cameras via ethernet cabling.Based on coaxial cabling technology. It is used to connect cameras via coaxial cabling.
ConfigurationManual or automatic configuration. Sometimes difficult, especially in terms of assigning IP addresses.Plug & play
InstallationDahua NVR setup is easier and more flexible. No need to install cables on the NVR recorder. PoE provides both power and network to the cameras through a single cable.More difficult. Several holes must be drilled in the walls to route the cables to the DVR.

5 Best Dahua Security Cameras & Recorder Systems 


How far can a PoE camera be operational?

IP security cameras use cat5e or cat6 network cables. The connection between an IP camera and a Dahua NVR is made by Ethernet cables. Due to signal attenuation, the maximum transmission distance of the Ethernet cable is 100 meters. Therefore, the maximum distance the camera can reach from the NVR is also 100 meters. If users need to go beyond 100 meters, they can use an Ethernet extender which is a device that allows greater distances to be reached.
