Why is it in Hollywood movies every time there is a vent or AC unit someone has fixed little ribbons on it? Is that a thing americans do? Why? The vent in this movie is close to the floor in the toilets of a train. This implies someone got on all fours ON THE FLOOR OF A TRAIN’S BATHROOM to stick those ribbons there for a reason i can’t even begin to comprehend.
Why would you be using a camera? Is Hollywood inside you house lmfao. The vents are also easily reachable without a ladder, so you wouldn’t need a camera anyways? So why are you suggesting a camera?
This isn’t a thing in real life, never has, never will be. It’s a Hollywood trope…. Let’s see someone post a picture from their house, this isn’t a thing and people here are yanking your chain OP.

In my first comment I explained how it’s used in COMMERCIAL buildings.
And techs will use tools instead of ribbons, since tying ribbons to ducts, attract dust and can be a fire hazard, most codes explicitly forbid their use.
And great story about the hack company fixing your MUA and leaving their garbage behind since they were too cheap to pay someone to remove stuff they shouldn’t have put in in the first place.
It’s always funny when laymen’s try to say something they saw a hack doing is somehow an industry standard technique or something…. Anemometers are cheap and standard hvac tech equipment. Gives you an exact answer instead of, it flutters….
It’s a Hollywood trope, full stop. People think it’s used in real life since people see the trope and some idiot desk worker wants to think their AC isn’t working.
HVAC techs aren’t going around tying fire hazards that’ll collect dust and look like garbage in 2 weeks to vents people…. Hollywood really loves exposing rubes with these hella obvious fake tropes…
