I am about to install 6 speedomes on towers ranging from 300 to 700 metres from the control equipment (adpro,galaxy,etc). My first questions are regarding the power supply. I could really do without supplying 240v to the first tower for cost reasons so, what distances can a 24v supply stretch to without voltage drop? Do I have any alternatives other than 240v? I also intend installing redwall detectors on each tower (in conjunction with fence mounted 'acoustic' intruder wire)! I am certain I will suffer voltage loss with the PIR's but I will ask for more advice in the Intruder section. I will be using cat5 and active baluns for the video and telemetry which I have had success with over 1000m in the past. So any advice on the 24v supply to the domes would be appreciated. Thanks.

300 to 700m from PSU ??

I would say no chance at all of it working 100%

This should help you out...

It will help if you know the minimum volts required for the domes to work properly.

Thanks! Looks like i'm gonna need to run 240 then!

Unless you install bussbar trunking over 700m, it has to be 230v, dont forget complaince with the 17th edition

hi mate,

is it 24v ac or dc ? if its ac then i can show you a way of achieving 1000 metres without even 1 milivolt in drop also how many amps ?

why is the mains option costly ? is it so you can run many dome from 1 psu ?

Hi ICE,

Just out of interest how would you supply a load without incurring losses, if you can do it I'm off to get on the Dragons Den and make my fortune.

your a time traveller too ?

Ok, OK 14 weeks and counting LOL

why are you picking on your ICEbear for
