its not necessarily for camera sends, its more of what is being sent to you. if you ever need to take a PA feed or plug into a mult box, I always use this. not saying Ive used it a lot over the years, but its always in my kit in my "problem solvers" pouch. depends a lot on your style of work, but do this long enough and you'll plug into something that'll give you a hum and you'll need it.
