Our company has switched over to using CAT5e for many of our CCTV / Surveillance installations for many different reasons. Although, we seem to run into bad baluns fairly frequently like 3 out of 20 or so. Is anyone else finding this?
I think this a common occurrence especially now days. Baluns from china run 32 cents. You can imagine the quality you are getting. I think its safe to say this is whats happening to you.
