IP Cam Cloud - insecure video data in the cloud?

Question

CCTV

Good afternoon.
When using a cheap Chinese IP camera (such as Sricam), the video is transmitted to a smartphone by connecting to the cloud (for example videoipcamera.cn), using login and password authorization.
Question: do I understand correctly that all broadcast videos from all cameras are theoretically (and most likely practically) available to cloud owners? (especially considering the fact that the application from the market is not open source, and the cloud is also not "transparent"). Moreover, the Telnet port with an unchangeable root password is open in the camera's OS (maybe this is a trifle, of course, given NAT?...) The question is, how much do I open the cloud owners the ability to view from my camera?
Thank you.

Answer 1

Yes available. The software running in the camera remains a "Black Box" and what and where it sends can only be judged by external signs. So NAT and Firewall rules (in the router) will help you. May need to update the firmware - after the incident with camera-based botnets, some manufacturers removed backdoors from their firmware (after they were poked into this shit with their noses).

Answer 2

You understand correctly
If there is physical access to data, then it is there, no matter how much the owners of dropboxes swear and beat themselves on skinny plywood with the heel of their left hind leg. It is clear that they profit from premium accounts.
But after all, apart from the premium, they tolerate a huge army of freeloaders, without demanding anything from them! They don't even show ads in their client! This means that there must be some other profit that they receive and which would compensate for such very considerable costs. Guess which one?

Answer 3

of course if you use the cloud they can watch all the videos

Answer 4

Yes, and you should not count on nat, because the camera itself establishes a connection with the server.
