1 Port Passive Twisted-Pair Video Balun Transceiver for CCTV Surveillance Cameras

New design! it use a razor blade instead of a block terminal,this design can help you to reduce a lot of work such as peeling and screw fastening.no tools are request in installation.simpler and faster.It is a UTP(Cat5) Video balun unlike any other. its revolutionary advanced design requires NO TOOLS and connects in seconds.The exceptional interference rejection insures that crosstalk is practically eliminated. Two stage surge suppression provides added protection against transient voltage spikes.

Q: What does BNC stand for?

A: BNC stands for Bayonet Neill-Concelman. They are named after the bayonet locking mechanism and their inventors.

Q: What are BNC connectors commonly used for?

A: BNC connections are typically used on RF, video and ethernet applications.

Q: How can I tell the difference between a 75 ohm and 50 ohm BNC connector?

A: On a 50 ohm connector the center pin is surrounded by a white dialectric. On a 75 ohm BNC connector is surrounded by air (no dialectric)

Q: Can a 50 ohm and 75 ohm BNC connector be connected together?

A: 50 ohm and 75 ohm BNC connectors will mate with each other. At frequencies under 10 MHz the impedance mismatch will not have any affect. If you are above 10 MHz the chances of signal distortion becomes more significant.
