worried that the cameras could be used for disciplinary issues for the staff.

We did have one teacher who begged for a camera in his classroom because he had a group of 'mean girls' who started to report that he was sexually harassing them. We were able to get a camera in there, but there was a whole bunch of rules regarding who had access. Fortunately the camera footage was able to be used to prove that this guy wasn't doing what the girls said, but his reputation was shot, so he ended up moving across the country to teach in another state.
