Hikvision NVR and DVR DNS Configuration: A Comprehensive Guide211

Hikvision, a leading manufacturer of video surveillance equipment, produces a wide range of Network Video Recorders (NVRs) and Digital Video Recorders (DVRs) that are used globally. These devices heavily rely on Domain Name System (DNS) for remote access and network connectivity. Understanding how to configure DNS correctly on your Hikvision NVR or DVR is crucial for ensuring smooth operation, reliable remote access, and efficient network management. This comprehensive guide will explore the intricacies of Hikvision DVR and NVR DNS configuration, troubleshooting common issues, and offering best practices for optimal performance.

Understanding the Role of DNS in Hikvision Surveillance Systems

The DNS acts as a phonebook for the internet. When you access your Hikvision device remotely using its IP address or domain name, your device's request is first translated by your DNS server. This server maps the domain name (e.g., ) or IP address to its corresponding numerical IP address, enabling communication. For Hikvision devices, this process is essential for accessing the live feed, reviewing recordings, and managing settings through the web interface or mobile app. Without proper DNS configuration, you won't be able to remotely access your Hikvision NVR or DVR.

Types of DNS Servers and Their Impact

There are primarily two types of DNS servers relevant to Hikvision device configuration: public DNS servers and private DNS servers. Public DNS servers, like Google Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1), are publicly accessible and provided by third-party companies. They are generally reliable and offer high availability. Private DNS servers are maintained within your local network and are managed by your network administrator. Using a private DNS server offers more control and security within a controlled environment but requires more technical expertise to set up and maintain. The choice between public and private DNS depends on your network infrastructure and security requirements.

Configuring DNS on your Hikvision NVR/DVR

The exact steps for configuring DNS on your Hikvision NVR or DVR may slightly vary depending on the specific model and firmware version. However, the general process remains consistent. Typically, you'll access the device's web interface through your web browser by entering its IP address. Once logged in, navigate to the Network settings section. You'll find options to configure the DNS server addresses. Here, you can input the IP addresses of your preferred DNS servers. Remember to save the changes after configuration. For most users, selecting a reputable public DNS server is the easiest and most effective approach. However, if your network utilizes a private DNS server, you'll need to use the relevant IP address assigned by your network administrator.

Troubleshooting DNS Issues with Hikvision Devices

If you're experiencing problems accessing your Hikvision device remotely after configuring the DNS, several troubleshooting steps can be taken:
Verify the IP address and DNS server settings: Double-check that you have correctly entered the IP addresses of both your DNS servers and your Hikvision device.
Check network connectivity: Ensure that your Hikvision device has a stable network connection. Check the network cable, router settings, and internet connection.
Firewall settings: Ensure that your firewall isn't blocking access to your Hikvision device. You might need to configure firewall rules to allow inbound and outbound connections on the necessary ports.
Port forwarding: If you are accessing the device remotely, ensure that the necessary ports are correctly forwarded on your router to your Hikvision device's IP address.
DDNS service: Consider using a Dynamic DNS (DDNS) service if your Hikvision device's IP address changes dynamically. A DDNS service maps a static domain name to your constantly changing IP address, simplifying remote access.
Restart your devices: Sometimes, a simple restart of your Hikvision device, router, and computer can resolve minor network glitches.
Consult Hikvision documentation: Refer to the user manual for your specific Hikvision NVR or DVR model for detailed instructions and troubleshooting tips.

Best Practices for Hikvision DNS Configuration

To optimize your Hikvision surveillance system's performance and security, consider these best practices:
Use reputable DNS servers: Choose well-known and reliable public DNS servers like Google Public DNS or Cloudflare DNS for better performance and stability.
Regularly check your DNS settings: Periodically verify your DNS configuration to ensure it remains accurate and functional.
Implement strong network security: Protect your network with a robust firewall and secure passwords to prevent unauthorized access to your Hikvision devices.
Keep your firmware updated: Regularly update the firmware of your Hikvision devices to benefit from bug fixes, performance improvements, and security patches.

By understanding the role of DNS in your Hikvision surveillance system and following these guidelines, you can ensure optimal performance, reliable remote access, and enhanced security for your video surveillance network.
