daubs8 Posted March 28, 2008 Posted March 28, 2008 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.
whistle Posted March 28, 2008 Posted March 28, 2008 300 to 700m from PSU ?? I would say no chance at all of it working 100%
camstop Posted March 28, 2008 Posted March 28, 2008 This should help you out... http://www.pelco.com/support/tools/wiregacalc.aspx It will help if you know the minimum volts required for the domes to work properly. :
daubs8 Posted March 28, 2008 Author Posted March 28, 2008 Thanks! Looks like i'm gonna need to run 240 then!
spider Posted March 29, 2008 Posted March 29, 2008 Unless you install bussbar trunking over 700m, it has to be 230v, dont forget complaince with the 17th edition

Thanks. 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 ?
spider Posted March 29, 2008 Posted March 29, 2008 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.

"if you can do it I'm off to get on the Dragons Den and make my fortune" why are you picking on your ICEbear for
