Have new cameras, new customer and can not connect to cameras for initial setup
At the link below, select your camera model and search out the setup instructions. Make sure your phone is connected to a 2.4 GHz Wi-Fi network.
Welcome to the forums! You can follow the link that @oldgeek listed to find the Support pages, or provide as much info you can herr so the forum folks can get an idea as to your issues. Camera models, wifi system, app version, what step of install you are getting stuck in, etc. “Paint the picture”. Thanks in advance!
It may also help to temporarily turn off mobile data and any “private network” feature on your phone.
