I know its been discussed before, but I thought I'd share some side-by-side photos of domes vs. turrets with IR enabled in the rain. "EastFront" is a Dahua HDBW4231F-E2-M/M12 dual starlight mini-wedge (dome) mounted on a PFB203W wall mount bracket so the domes face downward. "Gate" is a Dahua HDW4231EM-AS fixed starlight turret on a PFA130 waterproof junction box. Both are essentially directly exposed to the elements as the eaves are short and several feet above, providing little to no protection. When the rain comes at just the right angle to blast the dome, you can see the result. When the rain slows or the wind changes, the drops on the dome do dissipate fairly quickly. Turning off the IR virtually eliminates this issue. (middle image) The shot from the gate camera was also taken during heavy rain and blowing drops will show up and even trigger the motion sensor, but do not obstruct the view even with the IR enabled. For me, living in a relatively dry climate, the tradeoff of being able to cover the entire side of the house with one camera was worth having the view obstructed occasionally. Your climate and needs may vary. I just wanted to show what can happen during a heavy wind-driven downpour to exposed cameras.
