I have been installing the Honeywell hd73 and hd4d outdoor cameras, I have had a problem with moisture collecting on the dome, I am wondering if anyone has installed these before and what is common practice as far as using silicone around the dome housing which I have done but my Honeywell rep says it not necessary. It hasn't even rained here and I have moisture issues twice now with a hd4d, the only thing I can come up with is that I put a little silicone inside the dome where the wires poke through the back housing and I am wondering if the moisture from the silicone is collecting on the lense while it is drying, though it should be dry by now, I have had it apart twice now. I am really at a loss...
