I have two IP2M-841 cameras, ultimately they will be on security duty. The one I have set up here, now works well as does the other one at a remote location. They (or the 4k version) would be handy in certain uses, if they had USB control and such, (think webcam type of application) My issue right now is the lag from the camera (plugged into ethernet) is huge through my router going to my laptop also plugged into the router, also the audio/video sync is off.
Just a thought.
