How to let officers pee without also letting them turn off cameras at every "inconvenient" time presents a challenge...
Why? They have no problem nudie-scanning the public at airports and calling their buddies over and having the chick pass through the machine a few more times if she's really hot.
They could have a button that turns it off for five minutes.
It could reactivate instantly if they start running, fighting, draw a weapon, etc.
