Waltero lets you uncover your blind spots, at the same time as saving on unnecessary truck rolls and inspections Our Edge AI interprets visual data locally to identify equipment states, detect anomalies, and monitor site integrity automatically.

Key Benefits:

  • Actionable Alerts Only: Forget raw footage. Receive specific notifications when a valve is open, a tank is overflowing, or a site is breached.

  • Remote Site Mastery: Monitor remote pumping stations, manholes, and facilities without sending a technician to "just take a look."

  • Edge Processing Efficiency: Low data costs and 10-year battery life because the "thinking" happens at the sensor, not the cloud.

Application examples

  • Physical States: Water levels, obstructions, flooding, valve/gate positions (Open/Closed), lever angles.

  • Volumetric Levels: Tank sight-glasses, hopper levels, and outdoor stockpiles.

  • Safety & Compliance: Fire gauge monitoring, exit obstructions, and site integrity

From Reactive to Predictive: Vision AI in Action at VA SYD and EMASESA

A new white paper from Waltero presents evidence from two utility deployments — VA SYD in Sweden and EMASESA in Seville — showing how continuous, camera-based monitoring combined with lightweight Vision AI shifts utility operations from scheduled maintenance to condition-based response. Inspection becomes continuous, costs come down, and remote assets stop being a blind spot.

Predictive Maintenance for Water Distribution Networks: From Reactive to Proactive Operations

Most of the assets that keep a water or wastewater network running — gullies, inlets, trash fences, pumps, CSOs, outfalls — sit out across the network and get checked when someone has time to drive past. Vision AI changes that, with the heavy intelligence in the cloud and a lighter model at the edge for sites where latency or connectivity demand it. Here's how the architecture works, and why the ROI shows up in smarter truck rolls long before it shows up in prevented failures.

New generation · W-Sensor V2

See every meter.
Even the hard ones.

W-Sensor V2 reads more meters, more accurately, and keeps working where connectivity doesn't. A full year of field learnings, built into one new generation of the sensor.

New on-device AI reading engineReads digits and analog dials right on the sensor. No connection needed to read.
Keeps measuring through outagesBuffers readings offline and sends everything once the connection is back.
App-ready by designOnly V2 works fully with the Waltero installation app.

What's new in V2

Seven upgrades. One sensor built for the field.

Pick a benefit to see what changed. Everything listed ships in V2 today unless it's marked otherwise.

Reads more meters, more accurately

A brand-new on-device reading engine finds the meter, isolates each digit and reads it — then checks the result against the meter's own history. Clock-style analog dials are now in scope too.

  • Next-generation neural reading engine A modern on-device detector and classifier, for markedly more reliable readings — with no connectivity required to read.
  • History-aware reading Every reading is cross-checked against the meter's recent trend, so a single misread digit can't corrupt the number.
  • Analog dial & gauge reading Reads clock-style needle meters, with colour-aware needle detection — a whole new class of meters V2 can serve.
  • Reliable rollover handling Consumption stays correct when the counter wraps (…9 → 0…).
  • Self-healing framing If reads start failing, the sensor automatically re-locates the meter window.
  • Cloud-tunable accuracy Reading confidence and framing can be tuned per fleet, remotely.
  • Broad camera-module support One firmware supports many camera modules, including 5 MP — simplifying hardware supply.

Connectivity you can rely on — and see

Connectivity is the pain point customers feel most in the field. V2 connects the best way each site allows, adapts to the local network, and shows operators exactly how well every sensor is connected.

  • Multi-transport by design Low-power cellular (Cat-M / NB-IoT) or Wi-Fi, so each site connects the best way available.
  • Works across geographies Automatic band selection finds workable cellular bands without per-site or per-carrier tuning — smoother rollouts across regions and networks.
  • Connectivity you can see Every reading carries live signal strength, signal quality, network mode and SIM identity — at-a-glance visibility per site and faster field triage.
  • Keeps measuring through outages Reads and safely buffers offline, then flushes on reconnect. A weak or intermittent link never means missing data.
  • Prepared for Cat-1bis Prepared The firmware is built ready for Cat-1bis (higher-throughput LTE), to widen carrier and coverage options further.
  • Prepared for CoAP Prepared A lightweight secure transport that removes per-image handshake overhead and makes image transfer faster and more reliable — a dropped connection resends only the missing piece of an image.

Longer battery life

An overhauled power-saving mode keeps the sensor asleep longer between reports, and trims the everyday draw everywhere else.

  • Deeper modem sleep Keeps the modem dormant longer between reports.
  • Idle-sensor power-down The motion/wake sensor powers off when not in use.
  • Scheduled reporting The sensor transmits only in operator-chosen windows.
  • Lower everyday draw A dimmed status LED and leaner Wi-Fi behaviour reduce awake time.
  • Less flash wear Rolling out Far fewer storage writes per reading cycle extend device lifetime — in final validation, rolling out to the newest units.

Secure by design

Only authentic Waltero firmware runs on the device, data is protected at rest and in transit, and hardening is an ongoing programme rather than a one-off.

  • Supports hardware secure boot & signed firmware So only authentic Waltero firmware runs on units built and provisioned for it.
  • Encrypted on-device storage Protects data and IP against physical extraction.
  • Encrypted cloud links TLS-secured communication to the platform.
  • Verified configuration Coming The sensor will cryptographically verify configuration sent from the cloud before applying it.
  • Continuous hardening An ongoing security-remediation programme across the firmware.

Serviceable from anywhere

Upgrade once, manage forever. Fleets are updated, tuned and diagnosed from the cloud — without site visits.

  • Over-the-air firmware updates Upgrade whole fleets without site visits; the sensor improves over the air with firmware updates.
  • Live remote configuration Reading intervals, camera, framing, thresholds and connectivity changed from the cloud.
  • Remote diagnostics Pull or clear stored images and logs, force a time resync, and read best-practice diagnostics remotely.

Rugged reliability

Hardened against the things that actually go wrong in the field: patchy networks, bad input and misbehaving servers.

  • Keeps measuring through outages Reads and buffers offline, flushes on reconnect.
  • Crash-hardened A broad robustness pass against field crashes.
  • Tamper-proof against bad input Malformed cloud configuration can't crash or misconfigure the device.
  • Battery-safe back-pressure Bad images or servers can't drain the battery in a retry loop.

Faster, app-guided installation

V2 and the Waltero installation app together give installers a guided, phone-based commissioning and servicing experience — live camera framing, on-the-spot alignment, sensor replacement, meter-photo capture and per-site device management.

  • Phone-based commissioning Installers configure and confirm a sensor over a local Wi-Fi hotspot — no cloud round-trip needed.
  • Live camera view + on-the-spot alignment The installer sees the meter framing and rotates the image to get it right the first time.
  • Faster first-time-right installs Fewer callbacks, cleaner data from day one.
Only V2 is fully compatible with the Waltero installation app. Upgrading the sensor unlocks the modern field workflow end to end.
