After a few months of using an Axis P1378 I remain disappointed in the image quality, compared to even the cheapest IP cameras I have that claim to be in 4K. In fact I was so disappointed in the footage after spending $$$ on the setup I got a regular camcorder with the same 1/1.8 sensor in 1080 and upscaled it to 4k in a video editor and added sharpening until it looked just about as good as this over-processed footage. I guess that's cheaper for them than just making a better camera.
The advertising worked on me though I guess, From a video quality standpoint I paid 3x the price for the same quality footage in a better enclosure. FYI you just can buy durable camera enclosures to suit your needs and still have money leftover to get another camera.
Now that's my rant about the video quality which I had particularly high hopes for, but beyond the footage being merely comparable to most other surveillance cameras available, you and your company will need to consider the warranty, security, scalability, plus your repair, replacement and installation budget etc, when choosing the cameras for YOUR particular project...
