How bad is CCA Cat5e cable

[BuckRogers]

I bought a roll of CCA Cat5e cable from dbg, only to realize later that it is CCA.
How bad is this. I'm wanting to use it for POE IP cameras - will it be less efficient than solid copper ?

Don't use it for POE. It generates heat and can damage not only itself but other cables nearby.
