Labeling could be a 14-page article all to itself, with every second page just repeating, "LABEL EVERYTHING".
That said, I've had instances where other trades (especially drywallers) will just hack off carefully-marked coils leaving you nothing.
To the rescue: Superior Essex and their "Cable ID" feature, in which the cable jacket includes a unique four-character alphanumeric identifier (in the form "AA11") along with every length marker (I'm sure others do this as well, but we get mainly Essex cable from Noramco).
Where we're doing multiple different bundles from a box, we'll designate each pull with a color, wrapping the bundles at intervals with matching PVC tape, as well as wrapping up the service loops and marking the camera ends of each cable with the color. Colored labels on the patch panel, bearing the ID of that cable, ties it all together nicely.
A floor plan showing camera locations can then show cable routing in multiple colours as well, to indicate the routes of separate bundles; the cable ID is also added to the drawing alongside its camera.
