Good point. There have been any number of times I've had to removed a taped joint. I bought a PTZ dome camera from China and they sent along the biggest roll of teflon tape I've ever seen. When I ordered a second one, it came with an O ring to provide the same waterproofing. I spent quite some time (as Tony warned I might) trying to find out more from the Chinese vendors to no avail. Oh well, the camera was 1/4 what US vendors wanted for the same thing that probably came with the same obtuse directions.
Going to deploy one this weekend - not sure I should water test it with the garden hose before bothering to climb the ladder. Apparently water can get in through the wire entrance to the threaded dome cap. But I'd rather do it with tape because it might have to be taken down to dry out if the tape/gasketing doesn't work.
I bought some (wildly overpriced) stuff called Sugru that is a hardening putty that I might use to seal the wire entry because it's fairly easy to remove.
