I'm wondering if I should be covering cameras with some sort of cover like this:

I'm thinking about getting a IPC-Color4K-T180, and judging by the wall bracket PFB203W | Dahua Technology (dahuasecurity.com), it doesn't look like it provides much cover. What are the recommendations for these professional grade cameras? They are IP67, but what about sunlight, rain, snow, are they meant to last a few years under the elements?
