From the manufacturer's data, the cameras are weathertight, and OK to use outdoors.
Here is what their PDF for this exact camera says about this:
"Environmental
Dahua cameras operate in extreme temperature environments, rated
for use in temperatures from
-30 °C to +60 °C (-22 °F to +140 °F) with
95% humidity. The camera complies with the IK10 Vandal Resistance
impact rating making it capable of withstanding the equivalent of 55 kg
(120 lbs) of force. Subjected to rigorous dust and water immersion tests
and certified to the IP66 Ingress Protection rating makes it suitable for
demanding outdoor applications."
However, I've read elsewhere that the plastic domes over this type of camera can degrade when exposed to direct sunlight, due to the UV radiation. I can't say whether that applies to this particular camera or not, though, and their wording above seems to say that it should be no problem. I've wondered several things:
Will blowing dirt and sand here (it's windy here in the winter) damage the plastic dome?
Will the camera itself be damaged if it's left "staring at the sun" all day.
Under an eave, in the shade, and aimed so it's not looking at the sun, I suspect they'd work well for a long time. But still, I often read that "dome style" cameras are not suitable outdoors. That seems odd since the dome ought to protect things a lot better than a "normal" PTZ camera whose articulating joints would be exposed to blowing grit.
Thank you so much for that! Your camera has exactly the same model and part number as mine (and the others), and yet, you get the bonus audio wiring! Very interesting. I wonder if people will all start getting the audio connections as the stock of non-audio ones is depleted.
I need to study the photos against mine better to see exactly what the differences are, but the board layout in yours is different than the board in mine based on a cursory examination.
I really appreciate the time and work it took to remove your already-installed camera and photograph it for us. That's a lot of work, and you have my thanks for taking that time.
Here are some photos of mine. If anyone wants to see full-resolution versions, I can post them easily enough.
Thanks for the reply, and the information, going to order one from Andy for testing. If I get a few years from it I will be happy 
Wow, there are a LOT of differences. Should've taken a full above shot like your last one.

Hi Guys, what temperatures are you seeing on your cameras (OSD). I am seeing 115F during the mid morning. Outside temp is 80F. I am in FLA, its not even summer...
night time it sees 96F.
Other than that, I am liking this camera.

I believe that is the temp of the processor, not the air inside the cam. They all run warm.
In that case, Dahua should fix that. Processor temperature isn’t useful to user.
Well I know you can set additional positions, but it seems like the "home" can't be changed? And this unfortunate because it makes my camera look at a wall.
Have you tried PTZ > Function > Idle Motion? You can set an idle time (in minutes) and then tell it either to start a tour, or go to a preset (which you can set on the line below it).

The Audio cables are the old version, new version there is not available anymore, i checked this with them before.
Tom I hope your still following this thread. Would you remember where you purchase the one with the pics from? I have purchased three of these cameras off Amazon vendors. I have one which the board and PCB's are an exact match of your pictures. It is excellent and very much a starlight in that it requires almost no light at all and provides clear color night vision. The seller for it is no longer available. I have two others that I have bought subsequently from other sellers which match the other individuals photos on this board and, although they work great and have a good clear low light, they cannot do low light color.
