DVR Network Connectivity
To ensure seamless connectivity and remote access to the DVR/NVR, follow these key guidelines:
Important Things to Note
Gateway Configuration:
- The correct gateway IP (Router IP) of the DVR/NVR network must be assigned.
- Ensure that the gateway is within the same subnet as the DVR/NVR for proper communication.
DHCP Settings:
- Disable DHCP in the DVR/NVR network settings to prevent automatic IP changes.
IP Address Management:
- The DVR/NVR IP must be unique and should not conflict with other devices on the network.
- Before assigning a static IP, check the network to avoid duplicate IP assignments.
Port Configuration:
- Verify the ports used by the DVR/NVR for remote access (e.g., HTTP, RTSP, and server ports).
- If multiple DVRs are connected, document the ports assigned to each to avoid conflicts.
- Ensure that the required ports are forwarded correctly in the router for remote access.
DNS Settings:
- Set the Primary DNS to 8.8.8.8 and the Secondary DNS to 8.8.4.4 (Google Public DNS) for stable network resolution.
Network Stability Checks:
- Verify the network cable for any physical damage or loose connections.
- Check the router’s firewall settings to ensure that necessary ports are not blocked.
ISP Considerations:
- If the ISP provides a dynamic public IP, configure DDNS (Dynamic DNS) for consistent remote access.
- Ensure the ISP is not blocking required ports.
Connectivity Testing:
- Ping the DVR/NVR from a PC on the same network to confirm it’s reachable.
- Check network status in the DVR/NVR settings to verify proper gateway communication.
By following these steps, DVR/NVR connectivity issues can be minimized, ensuring stable operation and seamless monitoring.
