How to Set Up Dahua CCTV Local Area Network (LAN)292

Setting up a Dahua CCTV Local Area Network (LAN) is a crucial step in ensuring the smooth operation and remote access to your surveillance system. By connecting your Dahua cameras and recorder to a LAN, you can monitor your property from anywhere with an internet connection, receive real-time alerts, and manage the system remotely.

Step 1: Gather Necessary Equipment* Dahua NVR/DVR
* Dahua IP cameras
* Network switch
* Ethernet cables

Step 2: Connect Devices to the Network Switch* Connect the NVR/DVR to the network switch using an Ethernet cable.
* Connect each IP camera to the network switch using an Ethernet cable.

Step 3: Assign IP Addresses* Access the NVR/DVR's web interface (default IP address: 192.168.1.108).
* Navigate to "Network" -> "TCP/IP" and assign a static IP address to the NVR/DVR.
* For each IP camera, access its web interface by entering the camera's default IP address in a web browser.
* Navigate to "Network" -> "TCP/IP" and assign a unique static IP address to each camera.

Step 4: Configure Network Settings* On the NVR/DVR's web interface, navigate to "Network" -> "General."
* Enter the LAN subnet mask (e.g., 255.255.255.0) and default gateway IP address.
* On each IP camera's web interface, navigate to "Network" -> "General."
* Enter the same LAN subnet mask and default gateway IP address as the NVR/DVR.

Step 5: Enable Port Forwarding* On your router's web interface, navigate to "Port Forwarding" or "NAT."
* Create a new port forwarding rule for each port used by the Dahua system, typically:
* NVR/DVR: HTTP (80), RTSP (554)
* IP cameras: HTTP (80), RTSP (554)
* Map the external port to the corresponding internal IP address of the device.

Step 6: Test the LAN Connection* Open the Dahua Smart PSS software on your computer.
* Enter the NVR/DVR's IP address and login credentials.
* You should be able to view the live feeds from the IP cameras.

Troubleshooting* Ensure that all devices are properly connected to the network switch.
* Verify that the IP addresses assigned to the devices are correct and unique.
* Check the network switch settings and ensure that the network is functioning correctly.
* Confirm that port forwarding is enabled on your router.
* If you encounter any issues, consult the Dahua user manual or contact technical support.

ConclusionSetting up a Dahua CCTV LAN is a straightforward process that allows you to remotely monitor your property, receive real-time alerts, and manage the system efficiently. By following these steps and troubleshooting any issues promptly, you can ensure a reliable and secure surveillance system.
