3rd party camera hardware with API

I hope questions about third party APIs are allowed. If not I guess a delete is in order. That said.... I am looking to do an app for dog owners, trainers and enterprises such as shelters & boarding, and a couple of features require access to one or more cameras in real time. So I have been looking for hardware that provides an API and coming up empty. So far as I can tell none of the major pet cam companies, like Furbo, Petcube or Eufy. Even security cameras like the TP-Link Tapo doesn't seem to. Am I just failing epically in my search formulation, or are all these companies playing the printer game and selling the camera cheap and making all their money in the monthly subscription to actually be able to use the hardware, and keeping that to themselves? And, can anyone recommend decent to good third party hardware that does provide a Swift API? Or am I better off just targeting the use of iPhone & iPad and Mac cameras? It's not ideal, but it's better than nothing.
