what is needed to interface with iOS or Android "doorbell cameras" on ubuntu?

[Mike Marchywka]

I've seen a couple products like this, 20 dollars for camera and intercom,

https://www.amazon.com/Doorbell-Wireless-Intercom-Rechargeable-Apartment/dp/B0BNVH3PSG/

Doorbell Camera Wireless,Smart Video Doorbell Cam Home Intercom HD Night Vision WiFi Rechargeable Security Doorbell Cameras,2-Way Audio,Cloud Storage,APP Control,Doorbell Camera for Apartment

but not sure what i need to talk to it from ubuntu or how to reverse engineer a protocol.
Any odea how it works? I've seen a lot of open RTSP ports on home appliances lately, does
it just do streaming? If it has a REST API https I could easily talk to that.

Thanks.
