I had a call once on a geared traction with a HW governor, trap call, governor overspeed switch tripped but not set. Father and roughly 10 year old son in car. Cars ran for 20 years and never had an issue and it's ran 2 years since and never had one issue. But the father/son said they most definitely didn't jump in the cab...
I agree on the cameras, they will pay for themselves many times over it sounds like. I have seen all different manner of cameras installed, even just had a customer put a battery powered Ring camera in his elevators. I reckon he's got good enough wifi and doesn't mind changing the batteries every few days.
