We've had this issue before and our ETLs got into hot water over it. Apparently they aren't supposed to use the cameras to watch tms. They're not really even supposed to be in the AP office. Only the ETL-AP and AP tms should be using the cameras. We were told that they can't coach you for something they might see on the cameras. The cameras are for catching shoplifters, both internals and externals.
This is just my experience. I don't know what the directives r best practice have to say about any of it.
