Forgot to mention, when you use one cable per camera you must double up 2pairs for power and1 pair for video signal, otherwise unused cores can pick up interference.

I've been installing cctv for 30 years and seen a great deal of changes. The biggest one is going over to the new generation of kit. The biggest problem is always caused by wrong spec cable. It doesn't matter how big the power supply is you have to allow for voltage drop over a long length of cable. The higher the current required the thicker cable. Even if you have a 20amp supply the cable has to be able to conduct it. 5 pair cat5 cable is only capable of running 1 camera properly over a long distance. If you try running more than one and suffer voltage drop you will suffer from co-channel interference. My advice is to run one cable per camera. This will cure your problems. Alternatively you could fit a localized power supply.
