Setting up Dahua surveillance over the public network allows you to remotely access and monitor your security cameras from anywhere with an internet connection. This guide will provide step-by-step instructions on how to configure your Dahua surveillance system for remote access.

Prerequisites
Dahua surveillance system with IP cameras installed
Router with internet access
Computer or mobile device with internet access

Step-by-Step Guide

1. Configure Router Port Forwarding

Log in to your router's web interface (usually accessible by typing 192.168.0.1 or 192.168.1.1 into your browser's address bar)
Navigate to the "Port Forwarding" or "Virtual Servers" section
Create a new port forwarding rule with the following settings:

Name: Dahua Surveillance
Protocol: TCP
Port Range: 37777 (or any other port you prefer)
IP Address: IP address of your Dahua surveillance server

2. Configure Dahua Surveillance Device

Log in to the Dahua surveillance device's web interface using the default IP address and password
Go to the "Network" > "TCP/IP" settings
Configure the following settings:

IP Address: Assign a static IP address to the surveillance device (e.g., 192.168.0.100)
Gateway: Enter the IP address of your router (e.g., 192.168.0.1)
DNS Server: Enter the IP addresses of your preferred DNS servers (e.g., 8.8.8.8, 8.8.4.4)
HTTP Port: Enter the port number you used for port forwarding in step 1 (e.g., 37777)


Click "Save"

3. Access Surveillance System Remotely

Open a web browser on your computer or mobile device
Enter the following URL, replacing "your_public_ip" with the external IP address of your router:

URL: your_public_ip:37777

If prompted, enter the username and password of your Dahua surveillance device
You should now be able to view live video footage from your security cameras

Tips
Make sure your router has a strong firewall to protect your surveillance system from unauthorized access
Consider using a Dynamic DNS service to keep your public IP address updated if it changes
Regularly check your surveillance system's logs for any suspicious activity
