Transmit power and video signals over standard UTP CAT5 cables up to 2000ft. The video/power balun system carries DC power along with video over standard UTP cable making your installation faster and easier. The 82-9300 UTP splitter/transmitter delivers power to all 4 cameras from a single power input terminal connection on the back (note: 82-9200, 12VDC, 1.5A power adapter for transmitter sold separately). The built-in DC plug on each of the 4 video/power baluns (#82-9295, sold individually) connects to each camera's DC12V power input jack so you don't have to worry about mounting the cameras within reach of a power outlet. The 4CH video balun (82-8140) receives the video signal from the 82-9300 transmitter over a single UTP cable and breaks the signal back out to 4 75ohm BNC connections (for connecting to DVR). The system transmits distances up to 1000' for color video and 2000' for black and white using category 5E or greater.
