Choosing between approaches
Three approaches to elevator IoT.
They solve different problems.
Most procurement decisions in this category go wrong because three quite different products get compared on a single price line. They solve different problems, and on a serious project two of them usually end up in the same building. Here is an honest account of what each one is actually for.
Side by side
What each approach is actually for.
If the project needs continuous visibility into mechanical condition and verifiable maintenance outcomes, acoustic and vibration sensing can provide a complementary layer of evidence alongside existing inspection and service systems.
The honest matrix
Which one answers which question.
Read down the left column, find the question you are actually being asked, and read across.
| The question you are being asked | OEM IoT | Camera-based monitoring | Acoustic + vibration |
|---|---|---|---|
| Someone is trapped — get them out | Partial | Yes — this is what camera systems are for | No |
| Which elevators in my portfolio need closer attention this quarter? | Depends on the platform and supported fleet | No | Helps prioritize supported units using continuous condition data |
| Is this elevator showing a developing mechanical anomaly? | Depends on the platform and available controller data | Not designed for mechanical condition trending | Flags sustained deviations from the unit’s operating baseline |
| Can I see when a service visit actually took place? | Depends on the platform and data access | Video record, if someone reviews it | Yes — service windows are recognized from the ride data |
| Did the repair actually fix the problem? | Partial | No | Yes — before/after at the same points |
| Can I monitor a mixed-brand elevator portfolio in one system? | Varies by platform | Often, for visual monitoring | Yes — across supported traction elevators |
| Can I adjust a door parameter remotely? | Yes — this is its job | No | No |
| Can operating-condition data support a building risk review? | Depends on platform access and data-sharing arrangements | No | Provides traceable condition records for review |
Acoustic and vibration sensing is designed for mechanical condition monitoring. Electrical and control-system faults — such as door-lock circuits, the safety chain and controller logic — require controller-level or other dedicated diagnostic data. Camera systems serve a different purpose, particularly passenger visibility, entrapment detection and event response. This table compares categories of product rather than specific vendors; capabilities vary by platform and deployment.
