I guess all you’d have to do is buy one of the holsters and take the transmitter out of it. But yeah, maybe a bit difficult to get
While you’re at it, see about making a receiver so you either know when a gun is drawn. Or someone is trying to spoof a drawn gun.
I’m not sure how they’d address preventing the cameras from going off all the time in the normal course of removing the gun from the holster such as at the station house or firing range. Just don’t wear a body cam then?
