Ask HN: Industrial smart glasses with online / offline capabilities?

I am working for a company that is providing technical support to farmers in rural areas. We have local teams for support, but they often have to collaborate with remote teams/specialists. Idea is to have the field technician equipped with smart glasses so that the remote specialist can work with something more than just static images and verbal descriptions. Does anyone have positive (or negative) experience with industrial grade solutions in difficult environments (think humidity, dust, temperature)? Ideally the solution should be durable, easy to operate, have good picture and sound quality and be well supported by the vendor. As farms are often outside 5G network reach, offline capabilities for just recording are also valuable.
