Baluns - I got this one wrong (with schematic)
I got this completely wrong. I expected it to be for galvanic separation and impedance matching between the 75 ohm CCTV output and the 100 ohm CAT5/6 cable.
In reality it's just for impedance matching.
In my defense, it is called a balun (balanced to unbalanced) and I'd describe it more as an impedance matcher.
If you want to know what that's about then here are some Wikipedia links with enough formulas to satisfy the most geeky data-nerd. For the rest of us it will make some pretty tough reading.
