The current campmeter is also added to the awp tower. It's added everywhere besides on top of a few surf platforms and all the edges of the surf platforms as well (but if you add the last, then you can only surf 14 seconds, before you will constantly start to die). The current problem is that it's bugged and it doesn't work for everybody always. I'm not going to tell you guys how to avoid the campmeter, but I know how to and it's quite ridiculous...
That's one of the reasons why we have the issue with the current campmeter, it's because some people can avoid it...
