What do preventable problems cost?

Noise complaints

Noise complaints are the most frequent complaint made in hotels, and only 25% of all noise complaints are reported. The other 75% show up in online reviews. Negative online reviews can cause you to lose up to 70% of future bookings.

Repeat customers spend three times as much as one-time customers do, and losing future repeat customers due to negative online reviews will harm your hotel’s reputation and delay its growth and profitability.

Indoor smoking

Indoor smoking in hotels requires stronger cleaning materials and more time spent cleaning the rooms, which ends up costing you. Indoor smoking can also result in burns, ash stains and odorous furniture, causing you to put the room out of commission for days or weeks.

An average indoor smoking incident in your hotel rooms can cost anywhere from $600 – $1,000 to clean. This does not include the loss of revenue from taking the room out of commission if the smoke damages are severe.

No proof of damages

While you might smell cigarette smoke, there is no way to prove it without Alertify. Customers can either refuse to pay or fraudulently charge back a deposit. If this happens, then your hotel is stuck with with the expense and limited or no evidence to dispute the claim.

How Alertify prevents the problem

Alertify device

The Alertify device is a small, plug-in room monitoring device that monitors noise decibel levels, indoor smoking and vaping, elevated occupancy and air quality of hotel rooms.

Real-time Notifications

If Alertify detects excessive noise or indoor smoking, you will receive notifications in real-time. These notifications allow you to address the situation immediately and, in doing so, prevent noise complaints or damage from indoor smoking.

Dashboard & Analytics

In the dashboard, you can view live graphs of the current noise, air quality values, temperature levels, and more for your rooms. You can also access historical data of past guest violations and download documentary evidence reports of guest violations.

After Incident Reports

After violations have ended, you will receive after incident reports by email that contain specific details of the violation that took place. These reports can also be downloaded from the dashboard, and used as evidence in the event of guest disputes or fraudulent chargebacks.

Yes, Alertify detects cigarette or vape particles through a sophisticated particle sensor

Yep. Our accurate particle sensor combined with smart software allows us to detect if somebody is smoking cannabis in one of your rooms

That’s the name of our game for business. We’ll let you know if a party is happening or about to happen based on active noise levels and increases in occupancy. If a large group walks into a two person room, you’ll know about it.

For hotels, we recommend one device per hotel room. For a very large suite or penthouse, more sensors provide better accuracy. 

Yes! When a guest violation such as indoor smoking or excessive noise comes to an end, you will receive an after-incident report. After-incident reports can be submitted as evidence in the event of deposit disputes or fraudulent chargebacks.

Room monitoring can positively effect your online reviews because it prevents noise complaints. Unreported noise complaints often show up on negative online reviews.
