Smoke, Vape & Noise Detectors

 ABOUT US / THE SENTINEL STORY

The Problem We Saw
The hospitality and property management industries have a massive, expensive problem: unauthorized smoking, indoor vaping, and disruptive parties cause thousands of dollars in property damage and lost revenue every year. When we looked at the current market for environmental sensors, we found a broken system. Competitors were charging $150 or more per room for basic, battery-powered sensors, locking property owners into complicated leasing contracts, and offering fragmented tech that only tracked one or two metrics.

The "Aha" Moment
We knew there had to be a smarter, more cost-effective way to protect commercial assets. Sentinel Asset Monitors was founded on a simple premise: enterprise-grade property protection should be comprehensive, affordable, and easy to own. By partnering directly with top-tier hardware engineers, we bypassed bloated industry markups to create a dual-node system. For a fraction of the cost of traditional sensors, our suite actively monitors vape vapor, smoke, fire hazards, noise thresholds, temperature, humidity, and carbon dioxide—all powered by continuous 110V AC commercial power so your maintenance team never has to change a battery.

Our Scottsdale Roots

We built this company to serve the people on the front lines of property management.
