I have tried separate power supplies with no luck. I don't think it's specifically a power issue. I did take a 750ft piece of siamese RG59 and connect to one of the rear cameras and it works perfectly. SO... will be installing four individual runs of coax. I will still power them locally from the cat5 at the rear junction. measure once...cut twice

I am getting poor picture quality (ghosting - water shed, tearing) from four cameras and need some advice: The setup is this: This is a stockyard where cattle are bought/sold/auctioned. Front area has 4 analog cameras that use cat5e with baluns for each run back to DVR. average run length 150ft (picture quality is really good on these- but not perfect) Monitor is standard TV using VGA port DVR is Q-see 8 channel with 1TB hard drive. The rear area is approx 750 ft from the DVR (which is in the front area) I have a single cat5e running from DVR to a small building in back (junction) where it splits out on individual cat5e's to each of four cameras. The video signal is straight spliced at the junction passing through from back to front. Power is inserted on two pair of each of the camera cat5e cables at this junction. so basically i have 4 video signals coming down the single cat5e cable from the junction to the DVR. If i unplug power to three of the rear cameras, the other one clears up. I have tried a ground loop isolator but not sure i even have the right version of that part (there are several different flavors) keeping in mind that is is about 750 to each camera from the DVR, is the next step to add three more cat5e cables direct to each camera to separate the video signals? OR should I pull RG6 runs for each camera? Trying to figure out how to identify the next and appropriate step to resolve this. Site is about 30 miles away, so i need to have plan in place before visiting (and perhaps a backup plan). Thanks in advance
