I have exactly those Hikconnect all over my house. I always felt unsafe about them. My house doesn't have a static IP, so obviously the only way for me to connect to them when I'm away is through an intermediary
Having some technical networking knowledge I disconnected them from the Internet and set up a VPN where my wife and I first have to connect to prior to viewing the cameras.
Why do I surveil my own home? Because I have small children, when my wife and I go out and they stay with a baby sitter it gives us peace of mind to have the ability to verify everything is good. Also although we trust the sitters, we trust them even more knowing they know there's cameras.
Why did I get the cheap ass sketchy cameras? Cause I'm a cheap ass. The system I have cost about 2K with installation and spending 2 or 3x was outside our budget.
