Ronnstor 0 Posted December 12, 2006 I have a corrosive environment. What camera manufacturer makes a NEMA 4 camera and enclosure? I thought a Sony RZ550 in a nitrogen filled enclosure might work, but I am told that the enclosure stays pressurized for about a year then it needs to be pumped up. I have heard rumors that Pelco may have one. Any ideas? Share this post Link to post Share on other sites
