Hey guys, I have a project for work where we'll be installing iPads outside each conference room for meeting schedules. In doing so, we're going to need some wall mounts that lock the iPad in place but have an opening in the back to run our lightning port. I'll be running Power over Ethernet to each of these rooms and using a PoE to Lightning adapter to keep everything charged. We absolutely do not want to create busywork for someone just to manage charging which is why I need the opening to run the cables. Any suggestions would be greatly appreciated, we're trying to stick to ~$100 per mount but there is a bit of room to go up slightly if need be. Thanks guys.
