RE: Splitting composite video

["Paul" <groups@xxxxxxx>]

Thanks Keith,



I'm feeding 5 CCTV cams into an Extron switcher (don't want to mess with
that). Unfortunately I've run out of outputs from the switcher (all going
to other destinations such as Kat5 recipients).



So, I want to split the signals before entering the switcher and feed them
into a capture card(s) on the Linux box I'm going to be running ZoneMinder
on.



Any clues to the circuit design/schematic?



Thanks,



Paul.

Depending on what the equipment is, if you can remove the 75ohm termination
>from
the signal.

If that is not an option you need an active buffer which can be as simple
as
a few resistors, couple of caps and a transistor per desired output.
