I think you need to read both and possibly involve the unions
for example they cant install them for prevention of crime
and then use them for time serving
but THAT could be remedied by ... telling you of the new use
however once you have plodded thro both
you will see that it ( CCTV ) may not be proportionate to the degree of damage
in whcih case you would need to go down the grievance path and then onto the ICO
you can see why I was saying the union rep should do this
as you could easily end up being fired for being a troublemaker
