This could be a termination problem. What type of cable are you using (coax, utp, fiber, wirless) and if its coax is it an all copper center conductor with 95% copper braided shield 75 ohms? Then are you using crimp on/compression or twist on bnc's? this will make a huge difference if its utp is it passive or active....another thing to check would be the device the video is going into (if there are loops we need to check all devices) remember you never want to loop through more then 4 devices....and the end device (dvr, mux, matrix switch,ect) need to be set to terminate or 75 ohms all others set to high z or un terminated... The best check is to take a meter and go to the cameras location and check back to the head end if you are getting a good termination (depending on the distance you see see some ware between 80-95 ohms)..good luck and if you have any questions please let me know
Your camera is defetive, ask to the technical person who can check this
