Identifying NVR Internet Issues and Common Problems:


  1. Ping the DDNS or IP address to check for connectivity. Use Command Prompt (CMD) and type "ping [DDNS or IP address]".
    • If there's no result, it could be a DDNS issue or an internet issue.

Common issues and solutions:

a. Request the building superintendent to reboot the modem, router, and NVR. b. Contact the ISP to ensure the modem is in bridge mode. c. Ask the building superintendent for a public IP address to determine if the DDNS is the problem. d. Run an Nmap scan to identify potential network issues.

  1. If you get a result from the ping, it may indicate a port issue.

Common issues and solutions:

a. Check UPnP settings on both the NVR and the router. b. Ensure that UPnP on the NVR side is set to manual and that the ports are correctly configured.
