Cameras are not allowed to be placed in the facility bathrooms or any bathroom for that matter. Thats voyeurism and against the law.
If you happen to spot a camera in the bathroom, get the name of the facility (and its operator) and inform your States Attorneys Office pronto. In addition to criminal charges being filed against the facility, the donor can also be entitled to civil remedy.

If in the event that an observed collection takes place, a live observer (who must be the same gender as the donor) must enter the stall with the donor and directly watch the flow of urine exit the body and into the sample cup. Mirrors are also not permitted.
