Have You Used Or Considered Inline Cutoff Switches For IP Cameras?

I was inspired to ask this because occasionally I have seen where this could apply in some cases. Especially where IP cameras are in sensitive areas like bedrooms.

This might have prevented the situation in the IPVM article "Florida Integrator Techs Found Not Guilty of Video Voyeurism", where two technicians were accused of accessing a couple's cameras in their bedroom and changing rooms. If a cutoff switch like the one below had been installed inline with the cameras in question, the couple could have easily shut down the camera at will without needing the technical knowledge if how to disable cameras in the system.
