We are trying to set up cameras to view LED digital signs. The video is always scrambled. It appears that the sign's refresh rate is much slower than any of the cameras we try, so we get flashes with the image, and then distrored noise. The cameras all work fine on the parts of the image that is not the led sign. Its like trying to use a camcorder to record a TV screen. The question is - are there any cameras anyone knows of that we can adjust the speed of the capture? Using a good quality digital SLR to photograph the signs we need to go to about 1/10th second shutter speed to get a 'full' screen. Changing the FPS on the DVR will not help, as its the camera itself that is capturing too fast. Any help would be appreciated!

Same reason for me - but for some reason mfgr says manual shutter will not capture sign image, only progressive scan will. I can't see why and was wondering if anyone else had same issue.

New Information The sign manufacturer now says we need 60 fps progressive scan in order to see the sign properly. Can anyone advise if progressive scan is necessary, or will shutter speed control all us to capture 1 field properly, and are cctv bullet cams even available in progressive scan??

Each sign has a static ip hardwired to allow our update software to upload the spots, also used to allow the software we designed to control brightness etc to be controlled remotely.

Thanks for the super fast reply. We are currently using rather cheap IR bullet cams, like what KGuard sells in their kits. The cam needs to be waterproof, IR should not be a necessity as its pointing at a LED sign thats on, and reasonably wide angle lens. The current lenses are just standard what comes with them and they are fine. Due to number we will eventually need - the cheaper the better, rather replace the odd camera than up the cost. The use is mostly to confirm sign is up and no missing modules etc, so hi quality is not the important factor here, just an image that you can see. Not and IP cam, current are bnc composite video out. Any suggestions?
