You want to install and operate a device at a remote site with restricted (or no) VPN access and where you don't trust the local staff?
A remote KVM, i.e TinyPilot will help avoid dealing with lack of trust in local staff. Additionally connection to the KVM can be done over LTE/Cellular if you don't trust the local connection too.
