Correct, one at a time on each bnc. The post on the overlay is very indicitive of this continuing problem. It does seem to have that look to it. Any thoughts perhaps in that direction?

We did try that this last weekend. Same problem persisted. I'm inclined to believe the cards are picking up interference, but not sure how 'possible' that is.

Where can we buy that? And anyone else, will it work?

We tried swapping out the pigtails themselves, but the same problem continued. And when we plugged in the portable/ remote video monitor at both end of the camera/ cable the pic is perfect. That being said, we have not tried the 1 at a time trial to see if its 1 bad seed causing all this. Will definitely do that next. Thank you very, very much for the response. Any other thoughts?

Just an update. We were told it could be a ground loop problem so plugged it into a battery backup and ran the entire system on battery. The same problem continued. Anyone have any additional ideas? Looking at it live-in it really 'looks' like some kind of frequency interference. Any ideas on that angle maybe? Any help or ideas would be appreciated. Thx

All those long white lines (I see about 6 in the picture) also move. They seem to be defined ghosting images of actual images in the shot. Then the more cloudy interference is with it as well. Thoughts?

Here is a pic - hopefully it comes through. The white moves on the actual, but from the static picture here you can definitely get the idea...

Hello all - Im hoping someone here can help... I am part of a crew that has helped install 16 systems into a series of cookie cutter restaurants. All the restaurants are similar in layout and equipment, and all 16 systems were built the same. The dvr systems are built using windows 7 with 2 pci-e digivue 8 channel cards, for 16 total cameras in each store. The cameras are your standard bullets and domes, all running into a box that powers up 24 cameras. In most locations, only 5-10 new cameras were added, and those are the only ones running on the new power box. The rest were left 'as is'. It must be stressed that at 15 of the locations, all using the same type of built system, everything is running fine - clear pictures. However, in our 'problem' location, we are getting severe ghosting on every channel. The older system was also a pc-based dvr, and worked just fine - no image quality issues. However, on the new system, even the old cameras have the ghosting issue - and they were untouched (plugged just from the old pigtails into the new). We plugged a portable monitor into the cameras at their installed locations, and the image quality was perfect. We also plugged the monitor in at the end of the cable line (at the dvr) and there is no image quality issue. The issue only shows up when the cable goes into the pc itself. We have tried 2 different pc's at this location (the other ran vista). On fresh installations of both, the image quality was significantly better (though minor ghosting still showed). However on both, the image quality has gotten much worse over time. At first, our new pc and the new power box were plugged into a UPS. This has since been taken out of the location. We have tried various outlets for both, tried moving the pc, etc... all to no avail. We have tried different sets of the digivue cards as well (switching in one of the older single 16 channel cards instead of the 2 newer 8's). The only possible difference is this restaurant location literally shares a parking lot with a power plant. If this is a problem though, the only question is, why didnt it bother the old dvr system? Any help or suggestions would be welcome...
