Question about Ubiquiti UniFi AP AC-LR

I have been operating several units outdoors on a farm for 3-4 years. Of course under the roof where it can't rain, but so far I haven't noticed any problems.
Certainly, sealed units would be more suitable.

The AP should not be mounted outside, it is not waterproof (at best in an outdoor housing). As it gets slightly warm during operation, it would also attract insects that climb inside.
UniFi offers separate transmitters for outdoor use, such as the Ubiquiti UniFi AP AC Mesh (UAP-AC-M).
