This seems like it would probably be trivial to defeat either via legacy tech or simply by removing/disabling the receiver, interrupting the signal itself, hacking the firmware, etc.
Police could try to counter this by using lights (either visible or anything a camera’s sensor can pick up) to blind the cameras, but then people could also start doing stuff like using polarizing filters to minimize this, hiding cameras, or some other more clever method I’m not smart enough to think of.
