Loitering and dwell time
Loitering and dwell time sensor monitoring
No cameras. Live operators, 24/7.
Restrooms, locker rooms and stairwells are where people are most alone and where cameras cannot go. A camera-free sensor knows when someone stays too long, stops moving or is joined by too many others, and the alert goes straight to the Sirix command center. A live operator responds on your site’s protocol, day and night, across the US and Canada.
Loitering and dwell time monitoring, also called restroom loitering sensor monitoring, uses camera-free sensors to flag when someone stays in a private space too long, stops moving, or when too many people gather. With Sirix, every alert reaches a live operator at a 24/7 command center, who responds on the site’s protocol, with or without cameras.

How does loitering and dwell time monitoring work?
The sensor measures presence and movement. The alert goes to a live operator. Your protocol decides what happens next.
Too long inside. The sensor tracks how long someone stays in a room. When a visit passes the limit you set for that space, an alert goes out with the room's location. Each site sets its own limits, room by room.
No movement. When a person inside stops moving for longer than expected, the sensor raises a stillness alert. In a restroom, that can be the first sign of a fall, a fainting spell, a seizure or a suspected overdose behind a locked door.
Too many people. The sensor counts how many people are in a space. A group gathering in a school restroom during class or in a stairwell at night triggers a crowding alert. To know what they are doing there, pair it with l'utilisation de cigarettes électroniques..
What a loitering sensor can flag
Heure
- A visit longer than the limit set for the room
- Presence in a room that should be empty after hours
- Repeated long visits to the same space
Mouvement
- A person who stops moving for longer than expected
- No motion after someone enters and the door closes
- Movement in a space that should be closed
Occupancy
- More people in a room than its limit
- A group forming in a restroom, stairwell or vestibule
- Live people counts for each monitored space
Manufacturer reported: detection types, ranges and limits vary by sensor model and are confirmed during your site assessment.

How a monitored loitering sensor alert works. Too long inside: a visitor passes the time limit set for the restroom, the alert reaches a live Sirix operator, who checks the hallway camera when one is available, can speak through a speaker in the room where one is installed, and notifies the site contact on the site's protocol. No movement: a person inside stops moving, the operator treats it as a possible medical emergency and sends staff or calls 911 on the site's protocol, with no voice intervention. Too many people: more people gather than the room's limit, the operator checks the hallway camera, can ask the group to clear the room through the speaker, and notifies staff. Every alert and response is documented.
Illustration, with time sped up. Each site sets its own limits, and its protocol decides every step.
La couche Sirix
The sensor knows something is wrong. A live operator acts on it.
A sensor can tell you someone has been inside too long. It cannot check on them, call for help or decide what to do next. Sirix connects to any sensor, camera or not, and a trained, bilingual operator takes every alert 24/7 and follows your site’s protocol to the letter. When cameras cover the hallway or the entrance, operators also check them through surveillance vidéo à distance. before and while they act.

The sensor raises an alert
Too long inside, no movement or too many people. The alert reaches the Sirix command center with the exact room and the type of alert.
An operator takes it
A live Sirix operator responds immediately. No alert waits in an inbox or on a phone that nobody checks.
Cameras add proof, when you have them
If cameras cover the area around the room, the operator checks who went in, whether they came out and whether anyone else is involved. No cameras? The operator still acts.
The operator follows your protocol
Your protocol sets the actions for each situation and their order. Depending on the site and the situation, operators can contact the person on site, use voice intervention where speakers are installed, call 911 or an ambulance, dispatch a guard through RSPNDR or your own guard agency, and notify the contacts you name. Every alert and response is documented.
A sensor knows someone has not moved. A live operator makes sure someone checks on them.
Il n'y a pas de caméra dans la pièce ? C'est justement ça.
La vidéo sert de preuve, jamais de condition préalable. Chaque alerte fait l'objet d'une intervention immédiate.
Lieux où les appareils photo sont interdits
Restrooms, locker rooms and changing rooms cannot have a camera. The sensor still knows when someone stays too long or stops moving, and a hallway camera, if you have one, shows who goes in and out.
Là où il manque des caméras
Stairwells, back corridors and storage rooms often have no coverage at all, and they are where people stay unseen the longest.
Dans tous les cas, les opérateurs agissent
With or without video, a live operator follows your protocol for every alert. The task leaves your team’s hands.

Le respect de la vie privée dès la conception
Safety in private spaces, without surveillance
Loitering sensors measure presence, time and movement, never identity. That is why they can protect the private spaces where people are most alone.
- That someone is in the room
- How long they have been inside
- Whether they are still moving
- How many people are inside
- Who they are
- What they look like
- What they say
- Any personal information
No video or audio is ever captured in the room.
Covered, moved or unplugged, the sensor tells our operators.

No personally identifiable information captured, manufacturer reported. Privacy requirements vary by jurisdiction, and capabilities vary by model.
Où cela fonctionne-t-il ?
Built for the spaces no one can watch
Loitering and dwell time monitoring belongs wherever someone can be alone behind a closed door. Sirix operators respond for every industry below.
Santé et résidences pour seniors
Patient restrooms, clinic washrooms and resident bathrooms are where a fall, a fainting spell or a suspected overdose can go unnoticed behind a locked door. A stillness alert brings a live operator, who notifies your staff or calls for medical help on your protocol, while privacy stays intact.
Retail, quick service and convenience stores
Public restrooms see long stays, drug use and unresponsive visitors, and your staff are often the ones who find them. With theft and violence rising, the National Retail Federation reports an 18% increase in shoplifting incidents and a 17% increase in theft-related violence in 2024. Operators respond to every restroom alert so your team does not have to guess.

Multifamily residential
Stairwells, laundry rooms, garage vestibules and common restrooms are shared, often empty and rarely watched at night. Alerts for long stays and after-hours presence reach an operator who checks nearby cameras and acts on your protocol.

Écoles et campus
Restrooms and locker rooms are where students gather out of sight during class, and where cameras are never allowed. Crowding and long stay alerts tell staff where to look, and stillness alerts make sure a student in trouble is found fast.

Quels sont les enjeux ?
When someone stays too long, minutes matter
Restrooms are where emergencies happen out of sight, and where staff are usually the first to find them. In a New York City business survey published in 2017, 58% of managers had encountered drug use in their business bathrooms, and 90% had no overdose response training. Loitering itself is not always a crime; local rules decide what counts as loitering. A response protocol decides what happens next.

Devoir de diligence
Staff, patients, residents and students count on someone noticing when something is wrong. A notification does not notice. A live operator does.
Responsabilité
When an emergency in your restroom goes unanswered, the exposure lands on you. A documented response changes that story.
Staff safety
Your team should not be the only ones checking locked doors. Operators share the load, around the clock.

Sensors protect people without watching them. Help arrives without a camera in the room.

Foire aux questions
Loitering and dwell time monitoring, answered
What is loitering and dwell time monitoring?
Loitering and dwell time monitoring, also called restroom loitering sensor monitoring, uses camera-free sensors to flag when someone stays in a private space too long, stops moving, or when too many people gather. With Sirix, every alert reaches a live operator at a 24/7 command center, who responds on the site’s protocol, with or without cameras, across the US and Canada.
How does a loitering sensor work without a camera?
A loitering sensor measures presence, movement and the number of people in a room using technologies such as radar or body heat sensing, depending on the model. It knows that someone is there and how long they stay, never who they are. When a limit set for the room is passed, it sends an alert to the Sirix command center.
Can a sensor detect an overdose in a restroom?
A sensor cannot detect drugs. It detects stillness: a person inside who stops moving for longer than expected. That can be the first sign of a suspected overdose, a fall, a fainting spell or a seizure behind a locked door. A Sirix operator receives the stillness alert and follows the site’s protocol, which can include notifying staff or calling for medical help.
What happens when a loitering or dwell time alert is triggered?
The alert reaches the Sirix command center with the room and the alert type. A live operator follows the site’s protocol, which sets the actions and their order for each situation. Depending on the site, that can mean contacting the person on site, checking nearby cameras, using voice intervention, calling 911 or an ambulance, or dispatching a guard.
Do operators need cameras to respond?
No. Sirix can be the command center for any device, camera or not. Without video, operators still follow the site’s protocol for every alert. When cameras cover the hallway or entrance near the room, operators also check who went in and whether anyone else is involved, which adds proof before and during the response.
How long counts as loitering in a restroom?
There is no universal limit. Each site sets its own, room by room. As an example, a British Columbia health authority trial sent alerts when a restroom occupant had not moved for one minute or had been inside for 10 minutes. Sirix configures limits for each space during setup and adjusts them over time.
Does a loitering sensor record video or audio?
The loitering and occupancy sensors Sirix monitors have no camera, record no video or audio and capture no personally identifiable information, manufacturer reported. That is why they can be used in restrooms, locker rooms and other private spaces where cameras are not allowed. Exact capabilities are confirmed during the site assessment.
Is it legal to put a sensor in a restroom?
Camera-free sensors that record no video or audio are designed for private spaces such as restrooms. Privacy requirements vary by jurisdiction, so Sirix reviews placement with each site during the site assessment, and sites should confirm any local notice requirements.
How much does loitering sensor monitoring cost?
Loitering and dwell time sensor monitoring in North America generally costs between $10.00 and $75.00 per device per month, depending on the services required. These are typical market rates, not a Sirix price list. Self-monitored service sits at the low end. Professionally monitored service with live operators sits at the high end. Sensor hardware and installation are separate, and a site assessment confirms the rate.
What is the difference between loitering sensors and loitering detection AI?
Loitering detection AI uses cloud analytics on cameras to flag people lingering at entrances, parking lots and building exteriors. Loitering sensors work without cameras, inside private spaces such as restrooms, stairwells and locker rooms. Sirix monitors both, and every alert from either reaches the same 24/7 command center.
Can the sensor tell when too many people are in a room?
Yes, on models with people counting. The sensor counts the people in a space and raises a crowding alert when the number passes the room’s limit, such as a group gathering in a school restroom during class or in a stairwell at night. A Sirix operator then follows the site’s protocol.
Which loitering sensors can Sirix monitor?
Sirix supports 500+ manufacturers and is technology agnostic. It connects loitering, dwell time and occupancy alerts from multisensor brands such as HALO, including its Amplify occupancy sensor, and Triton. If a device can send an alert, Sirix can receive it. Through its partners, Sirix can also recommend the right equipment for a space.
Where can loitering sensors be installed?
Loitering sensors suit closed or quiet spaces where people can be alone or out of sight: restrooms, locker rooms, changing rooms, stairwells, laundry rooms, vestibules and storage rooms. Sirix recommends placement during the site assessment.
Who responds to the alert?
A trained, bilingual Sirix operator takes every alert, 24/7. The site’s protocol decides who goes next: staff on site, a guard through RSPNDR or the site’s own guard agency, or 911 and an ambulance when the situation calls for it. The operator stays on the alert until the protocol is complete.
Can loitering sensors work with vape detection?
Yes. Many multisensors combine occupancy, dwell time and vape detection in one device. A crowding or long stay alert shows that people gathered, and vape detection shows what they were doing. Sirix monitors both through the same command center.
Which industries use loitering and dwell time monitoring?
Healthcare and senior living, retail and quick service stores, multifamily residential buildings, schools and campuses, and office buildings use it most. Libraries, municipal buildings and banks with ATM vestibules use it too. Any space where someone can be alone behind a closed door can benefit.
