The same way Nasa does. Or airlines. If you don't have one, you don't go. If your's isn't working, you don't go. Cameras should have the same checks that guns do before you go out. And yes, sometimes they break, but that should result in an appropriate error code. Finally, a hundred million cars run off computers in the US pretty reliably - police cameras should run with a similar level of reliability. If we've authorized people with the use of deadly force then we should take their cameras seriously.
