Just ask them if it's pure copper. CCA is "copper-clad aluminium", a product that is patently NOT pure copper ..but it *is* cheaper, and that's the draw card. See this page for some background; read further at your leisure.
When the basic cabling spec calls for a (nominal) 100m between devices, what do you define as long distances?
Frankly, because you just DON'T/can't truly know what you're dealing with, it's just kark cable. You want an idea of how bad? Call Rudi at Cable Applications and ask him his feelings on CCA.:erm:
and, frankly, the best way to run those *is* PoE.

But, some practical points to consider:
- it's not make to a standard, who is to say one outfit's CCA is the same grade as the same *cough* quality as the one made by anyone else - what is the published standard?
- for pulling wire (heh), it's stretchier ..and may break a wire somewhere in there. You won't know at the time, but will find out later.
- it has higher resistance, which affects signal propagation. That MAY bother you on a GbE network that you spank; and is something to fear if you run PoE down the wire: resistance == heat, and heat in bundled, no escape/vent route cables is ..not.. good. I also know that you're going the IP camera route (lurking rulz!)
- you're running infrastructure cable, something that goes in and tends to STAY in for many years: what's the benefit of cheaping out when your timeline is what - 5 years ...more?
No worries, happy to help (and save the world from the sin that is CCA!)
This is why I DESPISE wishy-washy terms like "proper". I HAD to know so I called and spoke with a guy I've dealt with before that I know to be on the ball and he gave me the stock code for the "UniQue" brand cable they push: KDUT8001-CCA ...CCA - 'nuff said. You may choose to buy it, but I certainly won't. Note: this has NOTHING to do with the "UniQue" brand in and of itself, this is only about that craptastic cable.
Your wallet would likely have known at the time
. Also, you would likely have seen in the labelling, PoE goes beyond what standard siwtches do, and will be branded as such.You want to, you really want to: it's just a whole lot simpler to run the one cable out to the respective cameras to be part of the network, and not have to worry about power too. It also centralises your power, and therefore makes it simpler to get your network/security core onto clean/backed up power.
The question is less will CAT5e suffice but rather will your (fully gigabit) cope with that kind of traffic ...what do you think?
Aye, basic VoIP phones tend to be 100TX; and if you're building for GbE, you have to run separate cables to the PCs and phones. Note that the two phones I linked are native PoE so it makes sense to not have to worry about power by going PoE; and, ultimately, if you're doing any kind of quantity of phones, you're just going to be better off with a PoE siwtch to handle the phones with a separate, main switch for the PCs, and you then bridge the two through one port on each.
