I am currently using nylon terminal blocks to connect up 12v dc to my cameras with internally and externally. There must be a better way!!

What is the preferred method of connecting 12vdc when you dont use the provided plugs from the psu? Internal and externally.

I have seen some terminal blocks which can be pulled apart, does anyone know what thesde are called?

I guess you are talking about Bullet cameras and fixed domes. If you dont have screw type terminal blocks, then just splice and tape, just as good once done neat and proper :-) Other Methods are soldering and heat shrink tubing.

Wholey Cow Rory!!! :roll:

yeah yah learn something new every day huh :D
