I normally work alone so I always use wire markers.
I also have multiple boxes or reels on the go at the same time.
The 3M brand wire numbers are the best. They are a cloth type with really good adhesive. The book comes in either #'s 1-45 or 45-90. Each page in the book has two long stickers and one single digit. I stick one on the wire end, the other on the plastic spout on the box or reel until I cut it, then transfer it over to the wire. The single can be stuck on the face plate, patch panel, or the floor plans.
With security, I draw a rough map of the place and mark on the drawing where all the devices are. I then stick the single digit marker on the drawing for each location and place it in the alarm panel box.
