Can any one point me in the right direction, I've been asked to quote for power supply only for 5-6 cctv cameras the distance of the cable is 1500 metres and have been told a maximum of 30 amps, doing cable drop calculations I'm coming out at over 95mm swa??? I must be doing something wrong? my heads hurting!!
 
Calculate for the actual current draw not the absolute maximum, 30 A sounds a lot for 5 cameras but perhaps they are PTZ. Run the cable as a ring if possible to reduce volt drop.
 
I think the solution might be to run a 230v ring, then a small local psu at each camera location?
Current will then be so low, volt drop will be negligible
 
just cameras, apparently they are roughly 5 amps per camera, but i have since found out that each column will have a poe that converts to 24v ac
