• Set the system language, time zone, and date/time.
• Create an admin password (use a strong, unique password with at least 12 characters, including numbers, symbols, and mixed case).
• Configure network settings (static or DHCP). For static IP, set the NVR to 192.168.1.100 (subnet 255.255.255.0).
• Enable ONVIF protocol (under System > Network > Advanced > ONVIF) to support third-party cameras if needed.

Once the NVR is configured, navigate to the Camera Management section (usually under Main Menu > Camera > Camera Management).

Step 2: Discovering and Adding Cameras Automatically

Dahua NVRs support Plug-and-Play (PnP) camera discovery via Dahua’s proprietary protocol (Dahua Discovery) and ONVIF. Here’s how to use the auto-discovery feature:

1. Connect your IP camera to the same network as the NVR (via PoE switch or router).
2. Power on the camera.
3. In the NVR interface, go to Camera Management > Add.
4. Click Auto Search. The NVR will scan the local network for available cameras.
5. Select the camera(s) from the list. You’ll see the camera’s model, IP address, and MAC address.
6. Click Add. The NVR will attempt to connect to the camera.

Note: If the camera is password-protected (default credentials: admin/admin123), you’ll be prompted to enter the username and password. Always change default credentials immediately after adding.

Step 3: Manual Camera Addition (When Auto-Discovery Fails)

Auto-discovery may fail due to:

• Cameras on a different subnet
• Firewall or VLAN restrictions
• Camera firmware issues

In such cases, use manual addition:

1. Obtain the camera’s IP address (check via camera’s web interface, label, or network scanner like Advanced IP Scanner).
2. In the NVR, go to Camera Management > Add > Manual Add.
3. Enter the camera’s IP address, port (usually 80 or 37777), username, and password.
4. Select the protocol (RTSP, ONVIF, or Dahua Private).
5. Click OK to connect.

Example: You’re adding a Dahua IPC-HFW3441E with IP 192.168.1.200. Enter:

• IP Address: 192.168.1.200
• Port: 37777
