If you would like to watch more than a few IP cameras, it’s recommended to use your NVR (Network Video Recorder) port settings (i. e. using the web client of your NVR) instead of those of every single IP camera.

If necessary, minimize the security and privacy levels of the browser to get the required plug-ins or built-in Active-X installed. (e. g. “Phishing and malware protection” or “Pop-up allowed” options may temporarily need change in defaults)

The same procedure applies to the second camera, but make sure you apply different Custom service name, Server IP address, External and Internal port numbers.
