Sense
A ceiling sensor's vape index, smoke, or sound level jumps past the alert level your school sets.

Sensors for the places cameras can't see.
Vaping in the restroom. A fight in the locker room. A server room overheating at 3 AM. Steadfast safety sensors measure the room, not the people in it: vape, smoke, THC, sound level, air quality, temperature, leaks, and tamper. When a reading spikes, an analyst checks the nearest hallway camera and gets the right person moving, with no cameras and no recordings in private spaces.
Where the sensors go
Three kinds of places, one set of eyes.
Private spaces
Restrooms, locker rooms, changing areas, the nurse's office, and counseling offices, where cameras never go.
- Vape, smoke & THC
- Sound spikes from fights or bullying
- Tamper alerts
Building systems
Server and network rooms, kitchens, boiler and utility rooms, where problems start when nobody's there.
- Temperature & humidity
- Water leaks & freezing pipes
- Smoke & carbon monoxide
Hallways & common areas
Corridors, gyms, and commons, working alongside cameras to catch what video alone can miss.
- Loud-noise spikes
- Gunshot sensors (add-on)
- After-hours motion
Where cameras can't go
No cameras in the restroom.
No cameras in the restroom.
Still not a blind spot.
Restrooms, locker rooms, and nurse's offices are where students need privacy, and where vaping, fights, and bullying often happen. Steadfast uses sensors there that measure the room, not the people in it: air, smoke, sound levels, and temperature. When a reading spikes, hallway cameras outside the door show who came and went.

What the sensors measure
Vape & smokeA vape index and smoke readings, with alerts the moment they spike.
THCTHC-specific sensing with an add-on sensor where districts want it.
Air qualityParticles, VOCs, CO2, and humidity: the signature of aerosols and sprays.
TemperatureOverheating server rooms, failed HVAC, freezing pipes.
Sound levelLoudness spikes that can signal a fight or bullying. Levels, not words.
Motion & occupancyCrowds gathering, or someone inside after hours.
TamperAn alert if a sensor is covered, sprayed, or pulled off the ceiling.
Water leakBurst pipes and overflowing sinks before the floor floods.
Carbon monoxideCO readings and alarm audio near boilers and kitchens.
GunshotIndoor acoustic gunshot sensors as a specialist add-on.

No cameras
Never in restrooms, locker rooms, or changing areas.
No recordings
Sound sensors measure loudness only. Audio recording is turned off in private spaces.
No guesswork
An analyst reviews every spike before anyone is sent, so staff respond to real events.
From spike to response
What happens when a sensor spikes.
A sensor alert on its own tells you something happened. Steadfast turns it into something an assistant principal can act on.
Check
An analyst reviews the reading and the hallway camera outside the door for who came and went.
Notify
The right administrator gets the room, the time, and the hallway clip, not just a beep.
Report
Patterns by room and time of day show up in regular reports, so you can staff and supervise where it matters.
Sensor scenarios
What the sensors catch.
Vaping in a restroom with no cameras
- DetectThe ceiling sensor's vape index jumps past the alert level.
- VerifyThe analyst checks the hallway camera for who came and went.
- RespondThe assistant principal gets the times and the hallway clip.
A fight in the locker room
- DetectSound levels spike and motion shows a crowd forming.
- VerifyThe hallway camera shows students gathering at the door.
- RespondThe nearest coach and staff are paged right away.
The server room starts overheating
- DetectThe temperature in the server room climbs past 85°F.
- VerifyThe analyst confirms the trend and the cooling status.
- RespondIT and facilities are called before cameras and door systems go down.
Questions
Safety sensor FAQ.
Do you put cameras in restrooms or locker rooms?
Never. Restrooms, locker rooms, and changing areas get sensors only. They measure air quality, smoke, vape, sound level, temperature, and tamper. Sound sensors measure loudness, not words, and audio recording is turned off in private spaces.
How do school vape detectors work?
A ceiling sensor tracks particles and chemical signatures in the air and reports a vape index. When it spikes past the level your school sets, an analyst checks the hallway camera outside the door for who came and went, and the right administrator gets the room, the time, and the clip.
Where else do the sensors go besides restrooms?
Anywhere a camera can't or shouldn't watch, or where nobody is around to notice a problem: locker rooms, changing areas, the nurse's office, and counseling offices; server and network rooms (temperature, humidity, leaks); kitchens, boiler, and utility rooms (smoke, carbon monoxide, leaks); and hallways and gyms (loud-noise spikes, optional gunshot sensors, after-hours motion).
Can the sensors detect THC?
Yes, THC-specific sensing is available as an add-on sensor where districts want it.
What if a student covers or damages a sensor?
Tamper detection alerts when a sensor is covered, sprayed, or pulled off the ceiling, and the hallway camera shows who was there.
