I thought this would spark some interest ... run your CCTV system and why not your lighting systems with the same wire?

I have been dabbling with LED lighting ... remotes and occupation sensors to come up with a solution to eeeishkoms failure to "keep the lights on"

Drop a small solar panel on the roof ... a charge controller ... a lithium battery pack (or cheaper option ... like a few lead acids to keep the price down) a few cat 5 cables and you have a huge money saving solution.

no electrician ... coc required ... it can join the band of highly paid "technician" level skilled installers ... the part I like is no need to conform to any standard ... the customer does worry about the wires all over the place.
