Hikvision NVR DNS Configuration: A Comprehensive Guide356

This comprehensive guide delves into the intricacies of configuring Domain Name System (DNS) settings on Hikvision Network Video Recorders (NVRs). Proper DNS configuration is crucial for a smoothly functioning surveillance system, enabling remote access, firmware updates, and seamless integration with other network devices. This guide will cover various scenarios, troubleshooting common issues, and providing best practices for optimal performance.

Understanding the Role of DNS in Hikvision NVRs

A Hikvision NVR, like any network device, relies on DNS to translate domain names (like ) into IP addresses (like 192.0.0.1). This translation is essential for accessing the NVR remotely via its designated domain name or accessing cloud services offered by Hikvision. Without correct DNS settings, you'll be unable to connect remotely, receive firmware updates, or utilize many of the advanced features available in the Hikvision ecosystem. The NVR uses DNS to resolve hostnames within its own internal network and for external connections to the internet.

Accessing the DNS Settings on Your Hikvision NVR

The method for accessing the DNS settings varies slightly depending on the NVR model and firmware version. Generally, you'll need to access the NVR's web interface using a web browser. The process typically involves:
Connecting your computer to the same network as the NVR.
Finding the NVR's IP address. This can usually be found through your router's DHCP client list or by using network scanning tools.
Opening a web browser and entering the NVR's IP address in the address bar.
Logging in using your administrator credentials. Default credentials are often provided in the NVR's documentation. If you've changed them, ensure you use the correct username and password.
Navigating to the Network settings. The exact location of this menu varies, but it's typically found under "Network," "System Settings," or a similar menu item.
Locating the DNS settings. These are usually labelled as "DNS Server," "Primary DNS Server," and "Secondary DNS Server."

Configuring DNS Settings: Different Scenarios

The optimal DNS configuration depends on your network setup. Here are some common scenarios:

1. Using your ISP's DNS Servers: This is the simplest configuration. Your Internet Service Provider (ISP) automatically assigns DNS servers when you connect to the internet. You can usually find these by looking at your router's configuration. Enter the primary and secondary DNS server addresses provided by your ISP into the NVR's settings.

2. Using Public DNS Servers: Public DNS servers, such as Google Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1), offer improved speed and reliability compared to some ISP-provided DNS servers. Using these public servers can enhance the responsiveness of your NVR, especially when accessing cloud services.

3. Using a Static IP Address and DNS Servers: If you're using a static IP address for your NVR, you'll also need to configure the DNS servers manually. This is common in corporate networks or when you need precise control over your network's configuration. Ensure the DNS servers you specify are reachable from your network.

4. Using a Domain Name: While less common for the primary DNS setting, you might use a domain name pointing to your internal DNS server. However, the NVR must be able to resolve this domain name to an IP address. This usually involves configuring your internal DNS server correctly.

Troubleshooting DNS Issues

If you're experiencing problems with your Hikvision NVR after configuring DNS, here are some troubleshooting steps:
Verify Network Connectivity: Ensure the NVR is connected to the network and has a valid IP address.
Check DNS Server Addresses: Double-check that you've entered the correct DNS server addresses. A single typo can prevent connectivity.
Ping the DNS Servers: Use the ping command (from your computer's command prompt or terminal) to check if your NVR can communicate with the DNS servers you've specified.
Restart the NVR: A simple restart can often resolve temporary glitches.
Check Firewall Settings: Ensure that your firewall (both on the NVR and your network) isn't blocking DNS traffic.
Consult the NVR's Documentation: Your NVR's manual provides detailed instructions and troubleshooting tips specific to your model.
Contact Hikvision Support: If you continue to experience issues, contact Hikvision support for assistance.

Best Practices for DNS Configuration

For optimal performance and reliability, follow these best practices:
Always use at least a primary and a secondary DNS server. If the primary server is unavailable, the secondary server will be used as a backup.
Use reliable DNS servers. Public DNS servers like Google Public DNS or Cloudflare DNS are generally reliable choices.
Regularly check your DNS settings to ensure they are correct and up-to-date.
Document your DNS settings in a safe place for future reference.

By following this guide, you can confidently configure the DNS settings on your Hikvision NVR, ensuring seamless operation and access to all its features. Remember to always consult your NVR's documentation for specific instructions relevant to your model and firmware version. Proper DNS configuration is a cornerstone of a robust and reliable surveillance system.
