How I've been waterproofing camera prior to install...... (Learning by seat of pants!!)

There is a LOT of Rain here in the Smokey Mountains! Western NC in the States! Humidity is a big problem for outdoor lights here.
I was quite concerned about this humidity, and the cameras....
I did extra waterproofing on the first camera, and my second will receive the same treatment prior to install...
My cameras: DS-2CD2042WD-1

First I tighten the three screws holding the camera together from rear... To make sure they are snug. I then squirt some 100% silicone glue in the 3 screw...
