A side-by-side comparison of features, pricing, long-term savings, and setup for Airbnb & Vrbo hosts and property managers.
If you run a short-term rental, two names come up in almost every conversation about noise monitoring for vacation rentals: NoiseAware and Alertify. Both plug into a standard outlet, watch for problems in real time, and alert you before a party spirals into a neighbor complaint or a fine. But they solve different-sized problems. NoiseAware is a focused, best-in-class noise sensor. Alertify is an all-in-one property monitoring device that also detects smoking, vaping, occupancy, climate, and more — usually for less money per year.
This guide breaks down how the two compare on the questions hosts actually search for: What does each cost? Which detects smoking? Which is easier to set up? And which is the better fit for a single Airbnb versus a 100-property portfolio?
The short answer
Choose Alertify if you want the widest protection — noise plus smoke/vape detection, occupancy counting, climate and tamper alerts — at the lowest all-in annual cost. Choose NoiseAware if your top priority is outdoor noise (pools, patios, fire pits) or you’re a large enterprise standardizing on its Noise Score ecosystem.

Feature comparison
The clearest difference is breadth. NoiseAware does one thing extremely well: it measures sound and converts it into a proprietary Noise Score that filters out false positives better than raw decibels, then triggers automated guest messages (AutoResolve). Alertify covers noise too, but adds the other violations that actually cost hosts money — indoor smoking and vaping, unauthorized extra guests, and climate issues like mold risk.

Where NoiseAware pulls ahead: its Pro Outdoor sensor is the only weatherproof unit in this comparison, purpose-built for pools, decks, and large lots where outdoor gatherings drive complaints. If most of your risk is outside, that hardware edge is real.

Cost comparison
Alertify bundles the device, dashboard, and guest verification into a single annual price: $145/year for the all-in-one plan, or $195/year for AQI+ (adds extensive air quality and CO2 monitoring). NoiseAware charges $15/month billed annually ($180/year) for software plus one indoor sensor; the weatherproof outdoor sensor is a $99 one-time add-on.

| Plan | Year 1 | Annual after | Hardware |
|---|---|---|---|
| Alertify (all-in-one) | $145 | $145 | Included |
| Alertify AQI+ | $195 | $195 | Included |
| NoiseAware (indoor only) | $180 | $180 | Included |
| NoiseAware (indoor + outdoor) | $279 | $180 | +$99 one-time |

Future savings & total cost of ownership
Because Alertify includes hardware in a lower annual fee, the gap compounds over time. Over three years, the all-in-one Alertify plan runs $435 per property versus $540 for NoiseAware indoor-only and $639 once you add the outdoor sensor.
Figure 6. Cumulative 3-year cost of ownership, per property.
| Plan | 3-yr total | vs Alertify | Delta |
|---|---|---|---|
| Alertify (all-in-one) | $435 | — | baseline |
| Alertify AQI+ | $585 | +$150 | +$150 |
| NoiseAware (indoor only) | $540 | +$105 | +$105 |
| NoiseAware (indoor + outdoor) | $639 | +$204 | +$204 |
Figure 7. 3-year cost delta vs the Alertify all-in-one plan.
That per-unit gap becomes meaningful at scale. Compared with NoiseAware indoor-only, Alertify saves roughly $105 per property over three years — before counting the avoided cost of a single smoking-violation deep clean or a fine for unauthorized guests, which Alertify is built to catch and NoiseAware is not.

Small hosts vs. large enterprise customers
The right pick shifts with portfolio size. A single-property host cares about all-in cost and catching the violations that ruin a listing’s reviews. A large property manager cares about standardization, portfolio dashboards, and vendor track record.
| Small host (1–5 units) | Large enterprise (50+ units) | |
|---|---|---|
| Top priority | Low all-in cost, broad protection | Standardization & portfolio reporting |
| Alertify fit | Strong — cheapest all-in, smoke + occupancy included | Strong — management dashboard, PMS + API, per-unit savings compound |
| NoiseAware fit | Fair — noise-only, add-ons raise cost | Strong — used by 12 of the 14 largest PM companies in North America |
| Cost sensitivity | High — every dollar matters | High in aggregate — $105/unit × fleet |
| Typical winner | Alertify | Depends* |
Figure 9. Fit by customer size. *Enterprises weighing outdoor accuracy or an existing NoiseAware footprint may prefer it; those consolidating vendors and cost tend toward Alertify.
For enterprise noise-only deployments, NoiseAware’s scale is a genuine advantage — it’s the incumbent across most large North American portfolios. But managers who want to consolidate noise, smoke, occupancy, and climate into one device (and one bill) generally find Alertify both cheaper per unit and broader in coverage.

Setup & ease of use
Both are designed for non-technical hosts. Each sensor plugs into a standard wall outlet, connects to Wi-Fi, and is monitoring within about five minutes — no wiring, no cameras, no professional install.
| Setup factor | Alertify | NoiseAware |
|---|---|---|
| Install type | Plug-in, no tools | Plug-in, no tools |
| Time to live | ~5 minutes | ~5 minutes |
| Batteries / wiring | None (backup battery) | None |
| Mobile app | Yes | Yes |
| Outdoor install | Indoor units only | Extra step for outdoor sensor |
| Ongoing maintenance | Minimal | Minimal |

Practical takeaway: setup effort is essentially a tie for indoor use. Alertify’s single device doing multiple jobs means fewer sensors to manage per property; NoiseAware adds one quick step if you deploy the outdoor unit.
Which should you choose?
Choose Alertify if:
- You want one device that catches noise, smoking/vaping, and extra guests — not just noise.
- You operate in a permit market where unauthorized occupancy carries fines.
- You want the lowest all-in annual cost with hardware included.
- You manage a portfolio and want per-unit savings plus a management dashboard and API.
Choose NoiseAware if:
- Your biggest risk is outdoor noise from pools, patios, decks, or fire pits.
- You’re a large enterprise already standardized on its Noise Score ecosystem.
- You only need noise monitoring and value its false-positive filtering above all else.
Frequently asked questions
Is Alertify or NoiseAware cheaper?
Alertify’s all-in-one plan is cheaper at $145/year with hardware included, versus NoiseAware at $180/year plus a $99 outdoor sensor if needed. Over three years Alertify saves about $105 per property versus NoiseAware indoor-only.
Does NoiseAware detect smoking or vaping?
No. NoiseAware monitors noise only. Alertify detects cigarette smoke, cannabis smoke, and vaping in addition to noise.
Which is better for outdoor noise?
NoiseAware. Its Pro Outdoor sensor is the only weatherproof unit here, purpose-built for pools, patios, and large lots.
Do these devices record audio or video?
No. Both are privacy-first — they measure sound levels (and, for Alertify, air and occupancy signals) without recording conversations or using cameras, which keeps them compliant with Airbnb and Vrbo rules.
Which is easier to set up?
It’s a tie for indoor use — both plug into an outlet and go live in about five minutes with no wiring.
The bottom line
NoiseAware is the specialist and Alertify is the all-rounder. If your rentals live and die by outdoor noise, or you’re plugging into an existing enterprise NoiseAware footprint, NoiseAware earns its place. For most hosts and property managers, though, Alertify delivers more protection for less money — catching the smoking, occupancy, and climate problems that quietly cost the most, while coming in cheaper over the life of the device.
