People Counting Sensor Technology Explained
A people counting sensor is a ceiling- or door-mounted device that tallies individuals crossing a defined line or region and outputs an anonymous numeric count rather than video. Milesight 3D Time-of-Flight models reach up to 99.8% counting accuracy with a measuring resolution under 3.5 cm — Milesight datasheet figures — and they satisfy the Privacy Act 1988 because no personally identifiable imagery leaves the device.
Five sensing methods solve different site problems across this people counting sensor range. Time-of-Flight emits 940 nm infrared light and reconstructs a depth map, so it counts in total darkness. Binocular stereo vision pairs two lenses for 3D imaging across wide retail floors. Dual passive infrared, thermal sensor people counting via thermopile, and infrared break-beam options cover budget passage work where overhead mounting is limited. Where you only need binary presence rather than a headcount, our Occupancy & Presence Sensors [Link to: Occupancy & Presence Sensors Category Page] suit better, and selecting the right people counting solution starts with ceiling height and walkway width.
| Model | Technology | Counting Accuracy | Max Mount Height | Transmission (AU915) |
|---|---|---|---|---|
| VS133 | Second-gen ToF + AI | Up to 99.8% | 3.5 m | LoRaWAN / PoE (VS133-P) |
| VS135 | Ultra ToF + deep-learning AI | Up to 99.8% | 6.5 m | LoRaWAN / Wi-Fi HaLow / 4G / Ethernet |
| VS125 | Binocular stereo vision + AI | Up to 99.8% | 6 m | LoRaWAN / PoE / Cellular |
| VS350 | Dual passive infrared | Single ~95% / Multiple ~80% | 3.0 m | LoRaWAN / Milesight D2D |
| VS351 | Thermopile + radar | Up to 90% | ~3 m | LoRaWAN / Milesight D2D |
| VS360 | Infrared break-beam (paired) | Up to 80% | Wall / door | LoRaWAN / Milesight D2D |
A robust people counting solution follows a short hardware-led sequence:
- Measure mounting height — Confirm floor-to-ceiling height; ToF and stereo vision need 2.2 to 6.5 m clearance.
- Map entrance width — Match detection coverage to doorway or corridor span to avoid edge miss-counts.
- Set accuracy target — Specify ToF for over 98% retail conversion data; beam counters suit rough footfall.
- Confirm privacy scope — Select anonymous ToF, thermal sensor people counting, or beam where image capture is prohibited.
- Plan the backhaul — Pair each people counting sensor with a LoRaWAN gateway [Link to: LoRaWAN Gateway Category Page] or PoE switch for clean data egress.
People Counting Sensor Range from Milesight
The people counting sensor range from Milesight groups six models by sensing physics: Time-of-Flight, stereo vision, passive infrared, thermopile, and break-beam. Each unit also acts as an occupancy counting sensor or directional counter, and every model carries the AU915 LoRaWAN radio at up to 22 dBm transmit power, storing counts locally for retransmission after a network outage.
Milesight VS133 ToF Counter
The VS133 [Link to: AI ToF People Counting Sensor VS133 Product Page] is a second-generation ToF counter that builds a 98 degree by 80 degree depth map to separate overlapping bodies. It filters U-turns, differentiates adults from children, detects lanyard-wearing staff, and works as an occupancy counting sensor across up to four regions, fusing up to four units for wider coverage. With 4 GB onboard flash, the VS133 retains roughly one million counting records, and the VS133-P [Link to: AI ToF People Counting Sensor VS133-P Product Page] variant adds Power over Ethernet with BACnet/IP for native BMS integration.

Milesight VS135 High-Mount Counter
The VS135 [Link to: Ultra ToF People Counter Sensor VS135 Product Page] is a high-mount people counting sensor rated for ceilings up to 6.5 m, covering 22.05 m² per unit. Its deep-learning algorithm sustains up to 99.8% accuracy in tall lobbies and atriums, and the ToF illuminator dims when no presence is detected to conserve power. As a high-mount counter, the VS135 spans LoRaWAN, Wi-Fi HaLow, 4G, and Ethernet for flexible backhaul.
Milesight VS125 Stereo Vision Counter
The VS125 [Link to: AI Stereo Vision People Counter Sensor VS125 Product Page] is a binocular stereo vision counter that combines two lenses with RGB imaging and AI to count across floors up to 6 m high. It recognises dwell time, line crossings, and regional headcount, and stitches up to 16 units for shopping-centre-scale coverage. Automatic tilt correction and infrared light adjustment hold accuracy near 99.8% as conditions change. As an occupancy counting sensor, the VS125 maps net headcount per zone; for full video surveillance, specify the network camera range [Link to: Camera Category Page] instead.
Milesight VS351 Thermopile Counter
The VS351 [Link to: Mini AI Thermopile People Counter Sensor VS351 Product Page] is a compact thermal sensor people counting unit that fuses a thermopile array with radar activation and a passive infrared trigger. Radar wakes the thermopile only when motion appears, extending battery life while counting bi-directional passage at up to 90% accuracy. This thermal sensor people counting method needs no ambient light and captures no personal data, so the VS351 suits private meeting rooms. As a Milesight D2D controller, it triggers lighting or mechanical plant directly without a gateway round-trip.
Milesight VS350 and VS360 Passage Counters
The VS350 [Link to: Passage People Counter Sensor VS350 Product Page] is a dual passive infrared passage counter delivering up to 95% single-person accuracy across a 2.8 m doorway at 3 m mounting, powered by two replaceable 2700 mAh lithium cells for roughly four years of service. The VS360 [Link to: IR Breakbeam People Counter Sensor VS360 Product Page] is a paired infrared break-beam unit that forms an invisible ribbon across an entry, counting interruptions regardless of ambient temperature or clothing colour. Both are anonymous occupancy counter sensor options for restrooms, back-of-house, and open thresholds.
Australian Building Compliance and Milesight Sensors
Every people counting sensor on this page feeds Australian compliance and rating frameworks, not just operational analytics. Under the NCC Section J of the National Construction Code, occupancy-driven controls cut conditioned-air energy, while NABERS (National Australian Built Environment Rating System) Indoor Environment scoring relies on verified occupancy density from each occupancy counting sensor.
Live headcount feeds ventilation logic governed by AS 1668.2, so outdoor-air rates track real occupancy rather than fixed schedules; pair the data with environmental sensors [Link to: Environmental Sensors Category Page] for full indoor-air-quality evidence. For Green Star Buildings v1.1 fit-outs, the same count data supports space-efficiency and wellbeing credits. Because each Milesight ToF, thermopile, and break-beam occupancy counting sensor captures no images, it aligns with the Privacy Act 1988 and the WHS Act 2011 duty to monitor safe occupant loads without surveillance. A compliant people counting solution therefore doubles as an audit instrument.
Why Specify Qantec for People Counting Sensors
Specifying a people counting sensor is the engineering task of matching sensing physics, mounting height, and network backhaul to a venue before procurement. Every unit Qantec supplies runs on the AU915 LoRaWAN band at up to 22 dBm, and the VS133-P exposes counts as BACnet/IP objects under ASHRAE Standard 135. Specifying a people counting sensor through Qantec returns a complete people counting solution, not just a line item:
- Local AU915 stock and dispatch — Every people counting sensor ships from Australian inventory, so project timelines never wait on overseas freight or grey-market parts.
- Engineer-to-engineer support — Our team sizes mounting heights, gateway capacity, each unit, and BACnet/IP points before you order, which reduces return visits and rework.
- Verified firmware and warranty — Hardware arrives on current, authorised firmware with full manufacturer warranty, never refurbished or parallel-import stock.
- Transparent project pricing — Trade accounts unlock the people counting sensor price breaks and priced-up bills of materials that tenders demand.
VS133-P Network Hardening and Encryption
Physical and network layers both harden a people counting sensor deployment. The VS133-P supports IEEE 802.1x port authentication, SSH, and HTTPS, so counts traverse the network encrypted rather than in clear text. Segment this traffic onto a dedicated VLAN, terminate remote access through a VPN tunnel, and restrict gateway logins with role-based access controls. Firmware integrity matters too: apply only Milesight-signed images, verify checksums, and disable unused serial ports to shrink the attack surface. LoRaWAN payloads carry AES-128 session encryption end to end.
Milesight VS133 and VS350 Technical FAQ
Does a people counting sensor work in complete darkness?
Yes. Time-of-Flight and thermopile units emit their own 940 nm infrared or read heat signatures, so the VS133 and VS351 count accurately at zero lux, unlike RGB-only cameras.
What ceiling height does the VS133 people counting sensor need?
The VS133 mounts up to 3.5 m with a 0.5 to 3.5 m detection range. For atriums and tall lobbies, specify the VS135, which is rated to 6.5 m.
Does ambient temperature affect the VS350 passage counter?
Passive infrared sensing loses sensitivity as ambient temperature nears body heat, so in hot plant rooms specify the temperature-independent VS360 break-beam counter instead.
How does a people counting sensor differ from CCTV analytics?
It exports only an anonymous count, never imagery, so it sidesteps the surveillance, storage, and Privacy Act exposure that camera-based analytics carry.

Extended People Counting Sensor FAQ
How many people counting sensors can connect to one LoRaWAN gateway?
One Milesight gateway such as the UG65 or UG67 supports dozens of people counting sensors, because each unit sends only a small periodic count payload rather than video. Capacity scales with the reporting interval and the AU915 duty-cycle limits; longer intervals let more nodes share the airwaves. For dense entrances, stagger reporting windows or add a second gateway to keep packet collisions low.
How do you connect a LoRaWAN VS133 to a BACnet building management system?
A LoRaWAN VS133 reaches a BACnet building management system through a Milesight gateway that decodes the count payload and maps it to a BACnet/IP object. On the UG65 or UG67, the built-in network server decodes the uplink, then the BACnet Server page publishes In, Out, and regional counts as analog objects with optional Change of Value notifications. Only the Ethernet VS133-P speaks BACnet/IP without a gateway; BACnet itself follows ASHRAE Standard 135 and ISO 16484-5.
What reporting interval does a Milesight people counter sensor use?
The Milesight people counter sensor reporting interval is configurable from 5 seconds to 86,400 seconds in the device web interface. Short intervals feed live occupancy dashboards; long intervals conserve LoRaWAN airtime and battery life on the passage models. Schedule Settings can pause uploads outside set weekly blocks, so a retail counter reports only during trading hours.
Why does a ToF people counting sensor show a red image over dark floors?
A dark or black floor reflects too little 940 nm infrared back to the sensor, so the live view turns red and counting accuracy drops. Raise the ToF Noise Filtering strength — Milesight suggests around level 2 in open areas and up to 10 in narrow ones on the standard unit — or enable Enhance Detection Mode. Mounting a standard model above 3.4 m can trigger the same red scene, so verify the height matches the variant.
Do two Time-of-Flight counters interfere when mounted close together?
Two Time-of-Flight people counting sensors mounted near each other can interfere, because both emit 940 nm infrared light. Assign each adjacent VS133 a different ToF frequency modulation mode in the settings to stop cross-illumination corrupting the depth maps. Keep any other 940 nm infrared source out of the field of view as well, since stray light produces phantom counts.
What clearance does a VS133 need from walls and obstructions?
A VS133 needs at least 30 cm clearance from walls on its short side and 50 cm on its long side, with no object inside a 30 cm radius of the lens. Mounting too close reflects infrared back into the sensor and produces an unusable red image. Above swinging doors, keep the door normally open or mount the unit on the opposite face, clear of the swing.
How do you set the target height range on a people counting sensor?
Set the maximum target height to the tallest expected pedestrian plus 0.035 m and the minimum to the shortest minus 0.035 m, which offsets the ToF sensor’s 35 mm measurement error. For a population from 1.6 m to 1.8 m, configure 1.835 m and 1.565 m. Correct bounds stop trolleys, luggage, and raised objects from registering as people.
Can a people counting sensor detect tailgating at a secure entrance?
Yes — the VS133 detects tailgating and card piggybacking by tracking each separate body crossing the line, flagging when two people pass on one card tap. Correlate the count with the access-control event to surface unauthorised entries at card readers and speed gates. Detection runs on the anonymous depth map, so it adds security analytics without recording identities.
What objects cause false counts on a ToF people counter sensor?
A ToF people counter sensor miscounts when an object’s depth profile stops resembling a human, so a wide-brimmed hat or a box carried at shoulder height can leave a person uncounted. A tall human-shaped object on a trolley can be counted as a person instead. Tune the noise filter, target-height range, and U-turn area to suppress these cases during commissioning.
How do you align multiple sensors for stitched coverage?
Align stitched sensors by overlapping their live-view markers rather than measuring physical offsets between units. Cut reflective staff-tag strips, lay them on the floor across the shared zone, then drag each sensor’s live view until the highlighted markers coincide. Accurate overlap prevents double-counting where two fields of view meet.
