kwkshift made it take longer for us to help him by not mentioning that he was preparing for being thirty feet up, where "pretty much" isn't good enough. (On the other hand, answering that you don't use one was not answering the question, and so, was not being helpful.)

I've done cameras eighteen feet up on a ladder where restaurant tables and fixtures that came in the next day made tweaking the camera later REALLY a pain. Since IP cameras don't have a video output per se, a monitoring device goes a long way toward simplifying the installation.
