Wifi is really trivial to break into and doesn't leave meaningful traces unless you really do some enterprise monitoring stuff.

Unlike breaking into your window, you are unlikely to get the cops to do anything if someone breaches your network. There's also direct and indirect financial incentive.

So now your entire livestreaming security setup depends on the security of your wifi network, which can be broken with $20 of dedicated hardware.

And yeah, if someone puts hardcoded creds into their cameras.. they probably do it for all their firmware. It doesn't even have to be malicious, it's just a lazy way to test and debug software.
