Solved! What is this?

This was installed into our in ceiling heating/air unit over night at my job. It was never been there before and my coworker was panicking and making a fuss about it.

Its a Mitsubishi ceiling cassette, that sensor lets the HVAC system know if someone is in the room. Its called 3D i-sensor

If you find this "exciting" have yourself checked out.

Let me Google that for you and your coworker:

The device mounted on the upper-left corner of the ceiling air conditioner unit is a Mitsubishi Electric 3D i-See Sensor(specifically part of the PLFY or PLA series 4-way cassette indoor units). [1]
Functionality & Features

Thermal Imaging: It uses an advanced infrared sensor to detect the exact temperature profile of the room by continuously scanning the floor and walls.
Occupancy Detection: The sensor detects the location, number, and heat signatures of people in the room.
Direct/Indirect Airflow: Using the occupancy data, you can configure the air conditioner via its controller to either direct airflow directly at people for quick cooling/heating, or direct it away from them to prevent uncomfortable drafts.
Energy Efficiency: When the room is unoccupied, the sensor automatically signals the unit to switch to an energy-saving mode or turn off completely, reducing energy consumption.

If you are experiencing issues with room temperature regulation, draft directions, or need assistance configuring this sensor using your remote control, please let me know your thermostat or remote model number!

had one of these at my old office too

So it IS a surveillance device….

Lol no its for hvac

u/DntCllMeWht 7h ago

But technically, it is a surveillance device.

In much the same way a motion sensor for controlling lights is, yes.

Yes. Yes it is.

Dont pick AI copyslop for post solves. This is a place for humans to interact and connect with other humans who have experience with things other humans want knowledge about.

If you were going to just accept an AI explanation you could have burned up a small lake to get your question answered all on your own.

That’s not AI. It’s a GIF from the movie Signs.

Sure right- and it's just YOU prompting OP to stay engaged by asking unsolicited follow up questions that are overly eager to helpful.If you are experiencing issues with room temperature regulation, draft directions, or need assistance configuring this sensor using your remote control, please let me know your thermostat or remote model number!

Sure riiiight- it's just definitely YOU prompting OP to stay engaged by asking unsolicited follow up questions that are overly eager to helpful like a clingy appliance salesman.

u/tommysteakbone 5h ago

Seems economically unjustified if only used for HVAC fine tuning. Can also be additional recurring revenue streams. Whoever owns the capture theoretically can resell it several times - maybe to energy auditors / researchers who need to fill large datasets, utilities, and surveillance companies can pay a retainer to be able to access it on demand when they're asked for site-specific or local data. Aggregating these data and cross referencing with license plate readers, outside cameras, security systems, facial recognition, and other types of identifiable individual data can be very useful. Finer and finer detail can lead to more individual types of thermal signature and other identifiers. Interesting to follow this as far as one can imagine it.

u/CharlesPrawnson 5h ago

I don’t disagree and they’re always going to know who’s hiding a stiffy.

u/CertifiedGlizzler 9h ago

Any chance the lights switch on automatically when you enter the room? This looks a lot like the motion detectors my job just put in for its auto light system. No camera in it.

0

u/NerdyAutistic 9h ago

Nope, the lights are not automatic and the building is never empty because someone is stationed here 24/7.

u/JediCarla 9h ago

It could be a motion sensor. It turns off the system when no one is in the room/building (or adjusts the temperature). It helps the company save money on their utility bill.

-11

u/NerdyAutistic 9h ago

We apparently make our own power and send it back to the grid so i dont know if this is true.

7

u/Valuable-Analyst-464 9h ago

Energy conservation in this case would mean that running the system less would allow the company to send more to the grid, to make them more money.

-2

u/NerdyAutistic 8h ago

This makes sense, thank you.

3

u/DeKwaak 9h ago

If they make their own and sell it to the grid, then it is still money saving, because they can sell more to the grid.

u/whiteboyfresh2316 9h ago

Tell your coworker that it's for surveillance. It records audio, video, and x-ray scanning to make sure your not stealing pens and Post-It notes out of the supply closet. 😁

u/franke_tsu 9h ago

seems to be a presence detection or light sensor...

2

u/Its_the_way_now 7h ago

Occupancy sensor

2

u/CaveCanem234 9h ago

Presence detection? Only thing that makes sense for it seemingly being added directly to the AC unit?

But also, it's a workplace, I'd generally say it's safest to assume anything you do at work is being monitored by someone

0

u/No_Arachnid6493 9h ago

I appreciate the paranoia, especially in the era of Flock-you cameras, but it's an infrared sensor.

While you were taking pictures of it, it was taking pictures of you.

We have this in our office. We wish we could have it where we get to pick which vent opens..lol.

Occupancy sensor. Usually for lighting . But can be configured for HVAC as well

Part of a mini-split AC system, with temperature sensor.

I believe that is an electro magnetic frequency clit stimulator.

It's a temperature and occupancy sensor for your dispatch centers air conditioner

it just looks like they did maintenance and one of the buttons/ switches to access the panel got flipped

u/BudgetPresent2089 9h ago

It's not a fastner because there is only 1. A side shot would show how much it extends, it's hard to decipher in your pictures. I can't tell if it's a ball or not?? It does appear to be some type of sensor and the best place to have a temperature sensor is close to the return grill (the center grill). I'm sure you can zoom in and see if it appears to be something different.

2

u/NerdyAutistic 9h ago

It does extend out into a some what dome shape but idk why this wouldve been added as our system is not new and has been in this building for several years.

2

u/Sensitive_Ad3578 8h ago

Because these systems are modular and a Mitsubishi rep likely contacted your building's engineering department telling about an upgrade that would provide more energy efficiency. These types of systems are becoming more and more common to save energy

u/FlattenInnerTube 7h ago

More efficient? So hotter in the summer and colder in the winter, right?

Yes, more efficient than heating/cooling a room that no one is in.

Split system ac unit, you usually see them in Data closets or rooms that have equipment to help keep them cool.

u/CowRepresentative468 5h ago

This is the equivalent of being offended over the movement sensor in my office that turns the lights off when they don’t detect movement for a period of time. I call it the heart attack preventer. If the lights in my office click off, means I’m sitting still for too long.

u/One_Bit_3839 9h ago

Its a camera of some kind it doesn't look remotely opperated but it is adjustable not sure why its on the AC unit though it doesn't look like any surveillance camera I've ever seen before.

u/realtorbrittyc 9h ago

Looks like a camera to me

Infrared sensor. There's no lens.
