I have absolutely no problem using these kinds of devices.
I have an old phone and a generic Play account that I used for setup so the companies have nothing of consequence but my public IP address. Setup takes less than 15 minutes and after that all Internet access is completely blocked just like it would be if I unplugged my cable modem. There is no way for the cameras to override my router settings.
My smart TV is much more of a concern.

So, what security cameras would you use or are you just back seat driving without a good suggestion?
