A:Answer Yes, in theory there should not be any issues. You just want to make sure you have a strong router and a good amount of bandwidth. Each camera will need to have its own IP address. You will still need to scan the QR code on bottom of second device to get it to show up on the phone app. Our tech support can be reached at 217-903-5037 Mon-Fri, from 8am - 8pm CST to assist if you have any trouble. The phone app will definitely let you add another 4 cameras though.
