I know a few people are having the same problem as me so I thought id post this as I don't see another forum like this. Basically I have disabled well over 10 cameras and no achievement I played though the whole game last night in one sitting and disabled all 13 cameras and still nothing, so if you have this problem please feel free to post or if you have a solution or an idea to get this  Please Please post. Thankyou

Clear your cache on your HDD and then try playing the game straight through again.

I actually got the achievement on my first play through without trying for the achievement.

Tried clearing the cache but still nothing Thanks anyway so im still looking for solutions

I will say it is glitched as well, as I have done the same thing.

I didnt get it either

Just an update for people having the same problem, i cleared the cache and disconnected from xbox live so i played the game offline and this didnt work either so i have run out of ideas any more ideas will be apprieciated thankyou.

Indeed it glitched for me as well,I disabled well over 10 and no chievo.
