The devices

A modular sensing system,
installed in about 15 minutes.

Every device uses non-invasive magnetic mounting. Installation requires no drilling or connection to the controller and can be completed during a routine maintenance visit. The design brief was simple: make installation straightforward enough to scale across a fleet.

01 · The sensing devices

Two that stay. One that travels.

The Fixed Monitor and the Point Collector work as a pair for continuous oversight. The Portable Inspector travels with the technician — on-site verification at the car top, the counterweight, the machine room or the pit. All three share the same sensing core and the same data model, so a portable reading and a fixed trend are directly comparable.

Fixed Monitor
CAR TOP · 24/7

Installed on the car top. Captures continuous vibration, acoustic and operational data on every trip, and powers the Point Collector over RS485. This is the unit that builds the long-term trend.

SensorsProfessional omnidirectional microphone, 6-axis accelerometer, barometer (optional)
Connectivity4G / Ethernet (optional)
InterfacesRS485 × 3, Ethernet port (optional)
Power100–240 V AC, 50/60 Hz — compatible with major markets worldwide

CAR DOOR · RS485

A second, smaller sensor at the car door. The door system has its own vibration signature, which a car-top sensor may not resolve cleanly, so it gets a dedicated measurement point.

HANDHELD · AC OR BATTERY

Fits in a toolbox and attaches magnetically in seconds — on the car top, the counterweight, in the machine room or the pit. It can run from 100–240 V AC power or a battery. A swappable external power bank keeps it usable at test points without an outlet.

02 · Three ways to deploy

Modular devices. Flexible deployment. From continuous monitoring through to on-site verification.

Most buyers start with one of the first two configurations. The third combines continuous monitoring with on-site measurement, creating a fuller workflow for investigation and verification.

DEPLOYMENT 01

24/7 always-on oversight

Fixed Monitor Point Collector

For aging units, high-traffic buildings, remote sites, or a portfolio-wide rollout. Vibration, acoustics, speed and door-zone data captured around the clock, with the AI raising warnings on its own.

  • Proactive alerts before a failure, not after
  • A passively collected, traceable operating record for each elevator
  • Maintenance effectiveness quantified visit by visit
DEPLOYMENT 02

On-demand measurement, where needed

Portable Inspector

For fault troubleshooting, post-repair acceptance, scheduled multi-point inspections and third-party verification. One device covers the car top, counterweight, machine room and pit — including points where there is no power to draw on.

  • Real-time curves on site, with voice annotation
  • Fully offline collection where there is no signal
  • Unlimited elevators and test points per visit
DEPLOYMENT 03 · RECOMMENDED

Monitoring and on-site verification, in one closed loop

Fixed Monitor Point Collector Portable Inspector

Continuous monitoring narrows attention to the elevators, suspected components and locations that warrant inspection. The portable device can then measure those points on site to help confirm the suspected source and assess severity. The two tools serve different roles: fixed monitoring captures long-term trends, while portable measurement supports focused field verification.

STEP 1 · WATCH
Continuous capture
Fixed Monitor and Point Collector record every trip, building a per-unit operating archive.
STEP 2 · FLAG
AI narrows the inspection scope
The system identifies developing mechanical anomalies and suggests the suspected component and inspection points.
STEP 3 · VERIFY
Confirm it on site
The Portable Inspector measures the same points on site, helping confirm the suspected component and assess severity.
STEP 4 · ASSESS
Quantified risk assessment
Trend plus field measurement produce a risk grade, a severity grade and a maintenance priority for the unit.

From reactive repair to predictive maintenance: continuous monitoring, focused inspection and data-based verification.

03 · Installation

About 15 minutes, within a routine visit.

No structural modification, controller connection or building-network integration is required. Installation can be completed by qualified personnel, in inspection mode, during a routine maintenance visit.

00:00 Arrive on the car top Standard maintenance access. No special permit, no shaft work beyond the routine.
00:02 Place the Fixed Monitor Magnetic mount onto the car frame. Getting the position right is what matters.
00:06 Place the Point Collector At the car door, linked to the monitor over RS485. Powered from the monitor — no second supply.
00:10 Power and connect Powered from an existing 100–240 V AC car-top outlet; 4G connects automatically. Ethernet is optional.
00:15 Unit appears in the dashboard Live data from the first trip. The baseline starts building itself from that moment.

What we do not need from you

No controller integration, building-network connection, drilling or permanent mounting is required. Installation is carried out in inspection mode by qualified personnel and can be incorporated into a routine maintenance visit.

What we do need

Normal maintenance access to the car top, an existing 100–240 V AC outlet, and about 15 minutes of a technician’s time.

Removing it is just as easy

Magnetic mounting requires no drilling or permanent fixture. One unit shows you what the data looks like; to evaluate a broader rollout, a multi-unit pilot can show how the system performs across different operating conditions.

04 · Compatibility

It does not depend on the controller brand.

Because the sensing is external and physical, brand compatibility is not a feature list we maintain — it is a consequence of the architecture. The practical question is not "do you support our brand" but "can a technician reach the car top".

Multiple brands

Global OEMs, regional manufacturers, and units whose original maker no longer exists. Mixed-brand portfolios sit in one dashboard.

A wide range of ages

Because each unit is measured against its own baseline, a 25-year-old elevator is a perfectly good subject — arguably the most valuable one.

Traction elevators

Our core focus today, and where the fault signature library is deepest. Hydraulic, screw-driven and other types of elevator need targeted adaptation.

Units nobody else will connect

An OEM platform will not connect a competitor’s elevator, and often will not connect its own older ones either. Those units are the reason this product exists.
