Correct. Any time you need to use Wi-Fi, you need to unplug the ethernet cable. The Ethernet Card does not need to be removed.
Wi-Fi is enabled by navigating to Settings > Advanced Settings > Wi-Fi
Another thing I neglected to mention, once you install the card and connect via ethernet, you will likely get a Wi-Fi error on the System Check page of the home screen. To resolve this, you will need to disable Wi-Fi Warning Messages in Dealer/Installer Settings.
Tyler,
Thank you so much for your guidance… I installed an ethernet card, disabled Qolsys WiFi … all good now. The Power G siren/strobe is next…
One more question… for ADC-V724 cameras, is SD card based on-board recoding possible with ongoing cloud event recordings as well as on-site ADC-CSVR126 NVR? It would make sense since if WiFi is jammed, the videos will be recorded on SD cards as cloud/NVR recording will be down.
