I suspect the reference to cctv is in regard to cameras not working or not switching to stair view when the entrance doors are opening double deck vehicles. It was a constant battle between drivers and engineering to get these addressed, with engineering classing this as acceptable, and drivers not. Because unless your daft you make sure people are off the stairs before you pull away, if you don’t have the camera view then it’s guesswork, and if someone falls then you’ll get hauled over the coals for it and a responsible. You’ll also get management arguing with you that it isn’t a defect that prevents a bus for going out in service, but they’ll pull you in for tea and biccies and hold you responsible if anything happens. Some drivers would even go as far to take the bus but tape off access to the stairs, and I suspect this is where the contention comes in. CCTV defects unless you were at a main depot rarely got addressed in an adequate timescale simply because staff that could exchange hard drives weren’t based there, and the rest of the system was maintained by external contractors for the most part.
