Is the location you want to put it right under an eave? If so, a dome should be fine. If not, I'd skip a dome and go for a solid turret. Domes hate getting water on the dome. Screws up both the IR and the optics. Turning the IR off (my preference with all cameras except PTZs) helps but still isn't good when there's precipitation. A good solid turret like a Hik DS-2CD2342WD-I would be preferable over a Hik 3345-I, but personally unless it's in a high traffic public area I'd go with two of the cheaper turrets and use the other one to protect the first one AND expand your coverage in other areas. On most homes, if someone is going to screw with your cameras you're vulnerable. A prybar or a dollar store can of spraypaint will defeat any camera, as will any mask. I like turrets over bullets in exposed areas because they're more accident proof in locations with kids, plus they're better than bullets for attracting spiders (no tempting area for a web in front of the lens with the sunshade) and better than domes for weather, particularly if you use the builtin IR. Domes work fine indoors and under eaves but suck in inclement weather when exposed to precip. I might choose a Dahua 4431C-AS over the Hik 3345-I as well. Nothing wrong with the 2342WD-I either except the price. It is a sturdier choice and a bit better camera than the cheaper plastic ones.
