Anyone know of security alarms that go off if RJ11 or USB jack unplugged?

Hello Reddiverse!

This one is eluding me because any attempts at searching inevitably get conflated with just trying to use a phone line for alarm systems.

I’m looking for a physical security device that will simply go off if an RJ11 or USB-host (or maybe RJ45 but would have to be ethernet passthrough) is unplugged. We have some devices that keep getting stolen and trying to figure out a simple off-the-shelf alarm system that can go off if they are unplugged. Could also work for USB as these devices do have an micro USB host connector on them. I have seen some charging cable alarms, but they seem to be based on detecting when the client device is disconnected, not the host device.
