The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
I couldn't find any trope about "enemy awareness meter" in general.
Tropeworthy? (thumb up)

I'd say so.
At first I was about to suggest Alertness Blink, but that's broader than what you specified because it's not limited to someone noticing their enemies.
If not for this anchor I'd be dancing between the stars. At least I can try to write better vampire stories than Twilight.
^ Though it has some videogame examples of the enemy type.
"Alerticon" might be a good name for it?

Giving this a bump; I have an example in mind if this is going to be turned into a TLP project.
A form of Visibility Meter for things like grades of Alertness Blink and Confused Question Mark representing "this guard is getting suspicious of the cardboard box with feet"
I think there's also a place for a sister trope under Video Game Interface Elements, though, for representing a character's status and/or current activity via floating icons over their head. You see this in all sorts of games- say, a Turn-Based Strategy might have a shield icon over a character given a Defend Command or an eye over a character set to overwatch.

Do we have a trope for the game mechanic in stealth-based games of showing the enemy's level of alertness as icons over their head?
