I agree.  I don't think they should say that the hub works with 16 cameras then limit the use of continuous recording to 4 devices.  I now have 5 cameras and I have to set one to Event Detection although that's really not what I want.

  @Wayne-TP On reddit thread I made on this issue there were multiple users that reported multiple cameras working just fine. Someone from TPLink chimed in that the limit was placed because of performance issue but did not elaborate further and ignored us asking for more details about it. At least they provided us with an explanation as for why some H500 are allowing more than 4 cameras. Although some user with fairly new H500 also reported being able to add more.

And a big reminder that US is not the whole world. When I open US tplink site the first thing that happens is I am told to move to my regional site. There was not a single mention of such limitation on our regional site. There was nothing about it in FAQ or in the User manual. And on Europe site there was just a very small fine print mentioning it.

  @PEIguy Unfortunatelly unless you got one of first H500s made then you are stuck with 4 cameras on 24/7. 16 supported cameras is basically useless functionality as regular tapo app already offers the same functionality of live view. And event based recording is gimmick at best and totally useless at worst.
