CCTV Problem

Sheilded Cat 5 is never a bad idea either!

Overkill, not required. Standard Cat 5 is fine.

What kind of wire do I need to use with NVT devices?
Use Unshielded Twisted Pair, Category 2 or better, 16-24AWG, stranded or solid. Using a multi-pair wire (six pairs or more) with an overall shield is OK.

Can shielded twisted pair be used?
Some customers have successfully used shielded wire up to a few hundred feet. However NVT does not recommend it. Its high-frequency roll-off will severely degrade the distance performance. Use of an amplified receiver can compensate for some signal loss. Multi-pair wire (six pairs or more) can have an overall shield without degradation.

Thats direct from NVT (on their website), and they know a thing or two about baluns...
