Switching Off Camera Mic, Preferably By Physical Wall Switch?

I have a law enforcement client that has a need to turn off/on a mic. This is preferred to be done by a physical wall switch. Easy enough to have a switch to turn off low voltage power to the mic. However the current system they have is NVR with only one external input (they need two) and cannot introduce the mic into the IP camera they have. The camera vendor has no other options but via software which is not preferred by my client. Any ideas? My option is to install a second system with cameras that have a mic lead on the camera and power separately.
