Baluns And Power (max Current Draw)

[Hooner]

No, one pair for video and one pair for power (so 2 spare pairs) .. the distribution hubs (in the pdf) are sealed, so unless I absolutely corned beef hash it using nasty ald' terminal strips I'm stuffed.

If tomorrows tests prove inconclusive and 24v doesnt work, I think I'll just run fresh "proper gauge" two core around the building for the power and tell them that's how it's got to be!

LOL Lots, COP enough said.

Not Much COP

whistle dont think the make of balun has anything to do with it realy, i would say that its an ohms law thing and the demand is too high for the cable size. 24v may help.. good luck

Well ... all cameras were being supplied 11.6v even the ones within 5m of the Balun power hub thing.

When the IR kicked in this shot down to 6v for two seconds then 0v

There was mention in the hub's wiring diagram that it was only suitable for 12v DC so I didnt chance putting 24v AC across it.

Instead I ran 1mm twin to each of the cameras and the problem was cured, got a constant 12v at every camera

Bloody cat5, useful only for non ir cams.

Thanks for your replies chaps.

Glad your sorted

I think COP is great stuff...for the price. Not their fault if the engineer doesnt understand the pretty basic

concept of V over IR and tries to power Infra red cameras, not even supplied by COP, over a single 24 guage pair.

Even high end manufacturers expect a little technical naus on the part of the bloke who specs the job.

Handy little bit of info for some though. Even for those who now have the benefit of hindsight!
