I use syscall call buttons for my restaurant business. They are not waterproof but water-resistant I’m pretty sure I seen a water proof version in their catalog.
Hi. Could you share a link? I’m not in a large city so I don’t have access to businesses that sell the fancy tech.
This is the place I bought my buttons from. I just googled a few keywords and out of the few places that showed up syscall seemed the most promising. The call buttons I’m using are solid, it’s been alomost 2 years since I purchased the items. Don’t have an opinoin on their waterproof models though.
