Why Standard Detectors Fail

What Our Customers Say

Trusted by thousands of happy customers

"My youngest had headaches every morning for weeks. First night with SenseGuard: 52 PPM in the hallway. Our furnace had a crack we didn't know about."

"Three winters with the same detector — never made a sound. I plugged in SenseGuard and it hit 38 PPM in under a minute. The water heater was venting wrong."

"First night I plugged it in, it read 14 PPM in the guest room where my grandkids sleep. My HVAC guy came the next morning. Every grandparent needs one."

The Origin

Captain Daniel Kent spent 9 years with the fire department. He'll tell you the call he can't shake wasn't a fire — it was a quiet house in the suburbs. Family of four. The CO detector on the wall, green light on, completely silent. They never woke up.

He went home that night and checked his own detector. Same model. Same green light.

The problem isn't that detectors fail. It's that they're built to wait — sometimes four hours or more — until CO reaches critical levels before making a sound. Long after headaches start. Long after a family has gone to sleep.

That's why Daniel and a group of first responders helped build SenseGuard. Not a louder alarm. A smarter one — showing the exact PPM in your air from the very first reading. So you can act before symptoms ever begin.

Frequently asked questions

Questions from Homeowners
  • Standard detectors only alarm above 70 PPM — after up to 4 hours of exposure. SenseGuard Pro displays live CO levels from 0 PPM, so you see danger rising in real time and act before symptoms even start. It also detects natural gas and propane, which most CO-only detectors miss entirely.

No. SenseGuard Pro uses professional-grade electrochemical sensors that distinguish between cooking vapors and actual CO, gas, or propane. You'll see zero false alarms from toast or stovetop cooking.

All three. SenseGuard Pro is a true 4-in-1 detector: carbon monoxide, natural gas, and propane — in a single plug-in unit.

Plug it into any standard outlet at eye level. Bedrooms, hallways near sleeping areas, and near gas appliances are ideal locations. The plug-in design means no ceiling mounting, no ladder required.

We recommend choosing your coverage based on the size of your living space:

  • 1 Pack → Best for bedrooms, offices, RVs, or small areas
  • 2 Pack → Ideal for apartments, condos, or small homes
  • 3 Pack → Most popular choice for family homes and multi-room coverage
  • 4 Pack → Recommended for full-home protection and larger properties

For the best monitoring coverage, many customers place one unit near sleeping areas and additional units near kitchens, garages, basements, or fuel-burning appliances.
