  • Noise in the UTP installations for digital recordings -burns more HD space?

    I just finished an installation, where we used cameras with built in video over twisted pair transmitters. We used (CAT5e) for wiring, and passive receivers at the DVR side. Two cameras were connected using coax (RG59U). The install went OK, the results were acceptable. I used a Camera Master from FM Systems to set the correct video levels.
    The problem I'm having - and this after a few weeks of recordings - the cameras using UTP are taking 50% more HD space than the camera running on coax. The view is similar, same motion zone, same hours of operations.
    I believe the video over twisted pair is inducing a lot of noise, which is recorded by the DVR as data?!
    Any thoughts, suggestions, comments on it?

    Attila, was an electronic footprint made of the facility? Was an event recorder used to determine the frequency, amplititude and duration of the noise? Have the technical folks determined if noise is inductive or radiative? What type of an electronic environment does this facility enjoy? Suggest you contact Herb Goldstein as he might be able to guide you better than I. Email [email protected]
