TLIK, this seems like a good approach and it would work with an observant therapist, but not like the doctor heterim, as ujm points out. I wonder whether the phone connection can indeed solve the problem. Just put the spouse/mother/friend on an app. Possibly just video, reduced resolution. If connection goes down, they should call the office to do a check.
One problem with the above is the experience of security monitoring. There is almost never a case when a security person discovers low-level crime in real time. It is after a computer is stolen, you can wind the tape and find the perp. But even a lapsed security monitoring should make the doctor aware of consequences. The key is that the monitor should be independent of the doctor.
