I prefer non-IP cameras so they can't be plugged into the internet. Yes, it's annoying to get a feed other than locally... but that is the whole point.
If you need nurses to remotely monitor patients that's fine, there's a monitor in the nurse station. If those "nurses" are on the other side of the world... then anyone, anywhere, can see those feeds and there's nothing you can do to stop it. We've all seen leaked video from "secure" military systems... how much more secure is your hospital IT system than that?
Back in the day I set up Zoneminder... pretty good. I was able to write a custom perl script to run a loud wave file in my house to tell me a zone was activated :)
