mshaffer 0 Posted November 30, 2014 Can anyone recommend a good brand and type balun for this type of connection? Not sure if active on both ends, etc.. Also do you think a balun will work in -15F cold if it's only rated for 32F? BTW the cable is cat5e UTP direct burial, solid copper. Thanks Share this post Link to post Share on other sites
survtech 0 Posted November 30, 2014 Passive-passive is good for up to ~1,000 feet. Active-passive (either end) is good for up to ~2,000 to ~3,000 feet. I would use a passive balun at the camera end and an active receiver at the head end. Typical passive baluns are rated down to -10 degrees Celsius (-30 degrees Fahrenheit). If installed in a heated enclosure, you wouldn't have to worry about the temperature. Share this post Link to post Share on other sites
