So Ive run into a problem. . .
I'm trying to power these 8 24vac cctv cameras for an art project - the technician at my school instructed me to daisy chain the cameras in series - explaining that in this way each camera would receive approx 30volts each (UK mains at 220vac) - we speculated that this should be well within tolerance for the cameras. So being as trusting as I am - whole hog went for it.
One pop later - and I think a few of these cameras have bitten the dust - never mind that my multiplexer now also seems to be on the fritz.
the question is - what SHOULD I have done? Running them parallel was clearly not an option - running them in series seemed to make sense. . .
Taking a multimeter to the mess indicated that current from the first to the second camera was hot at about 140vac, second to third at about 47vac and then things went down to about 3vac afterward. . . I don't really want to recheck those numbers as you can well understand.
Any ideas? - I clearly only know enough to get myself into serious trouble. . .
Cheers - ben
