By XGtE you MUST observe the casting components of the spell while it is being casted(V,S,M) or spell has visible effects. It says that it is impossible to determine the caster of a spell that is in effect.
Concentration is already too easy to break, so I would rule that are no visible effects on the caster.
Unless you see direct effect of the spell and you character knows that that spell requires concentration.
you can just hand wave it as "it's magic" so it works EXACTLY as I meant to it.
or maybe you have this kind of aiming device projected while you are casting fireball.
Can be anything...
same way you know if you are 155 feet away from your target, so you need to make 2 steps to avoid...

30ft is enough to walk around but not to useful for scouting

Yes, we could have a debate if we had...
