What is a balun?

A balun can send HD video up to 200M down CAT5!
Baluns contain small signal transformers that are specially tuned to match the cables impedance and convert the unbalanced signal to a balanced one. PASSIVE baluns just have the transformers and very little else in them.
On some PASSIVE baluns that carry video and data signals, the data terminals do not go through a transformer or any other electronics and are a direct electrical connection to the CAT5 cable. These terminals can be useful for lots of purposes including sending low voltage (5 or 12V) from one balun to another.

Working with CAT5 Cable
Baluns are a popular solution as they allow the engineer to use existing spare CAT5 cable runs within a building for the CCTV installation. They are a great way of adding extra HD TVI, CVI or AHD cameras to a remote part of the site.
