I think DS-7216HQHI-K2/P is a PoC DVR isnt?
Regardless, it looks like a power supply issue - perhaps the cameras are not suitable and require more power than the recorder can feed?
Thanks Xerob! Sorry, yes, that is what I mean - PoC DVR ... jsut really tired of trying to solve the issue for the last few hours!
How do I find out the power required vs suppled?
I've sort called it a day by now... but how will try tmrew.
I was also wondering if this may have something to do with faulty cables? Should I try using shorter cables?
I would check the power specs first to eliminate this as a problem. If this does not work, then check the cables!
