I installed CCTV at work not long back, and used cat 5 and cheap baluns, this worked well.
THe only problem i had was the psu and the dvr wernt that close, so i had a big mass of messy wire inbetween where i had to split the pairs in the cat5.
WHats the way around this? Runinng 2 cat5?
Also, ive seen some suggestions that power should be ran over 2 of the pairs, how and why would you do this?
WIth regards to pricing, ive seen the shotgun cable (with power) for about £28+vat, where as i can get cat5 for £15, so yes it seems cheaper.
