It appears that the Rocu cameras can be viewed on my TV with ROKU. So, if I have a TV with ROKU at our Florida winter home, can I view my cameras located at my Michigan summer home.
Also, can the cameras be viewed on a ROKU app on an iPad or IPhone from anywhere?
Yes to both as long as the Roku device or phone app is logged into the same Roku account that the camera is linked to. I'm not sure about "anywhere". I don't know, but I'd be surprised if "anywhere" includes outside the US.
Thanks,
Use the ROKU Home app?
Yes, not the one with the remote control.
