I currently have a single 5231R-Z camera and a 130E junction box but have not installed them yet. I have test assembled them and found that the rubber grommet through which the camera's cable passes makes adjusting the eyeball's aim difficult, at least on the workbench. Even though the PFA137 is open-faced, the metal hood that contains the camera should provide pretty good protection as the gap would be facing down or to the side. Would applying some dielectric grease to the RJ-45 connection and using the boot be enough to protect the connection? Anything else I may be overlooking??
