    The Problem Isn't That Homes Don't Have Detectors.

    Carbon monoxide is the #1 cause of accidental poisoning deaths in America.ΒΉ

    Over 400 Americans are lost to accidental CO poisoning each year, and more than 100,000 end up in the ER β€” per the CDC.ΒΉ

    Your smoke detector has one job. These are the four it can't do.

    The disc on your ceiling looks for smoke. That's it.

    It can't see the natural gas running through your stove, your furnace, or your water heater.

    It can't show you the carbon monoxide level in your air, it just stays silent until levels get dangerous.

    It can't tell you the temperature or humidity that affect your home and your health.

    And it's mounted near the ceiling, 8 feet above where heavy gases like propane actually pool, down low along the floor.

    The Sentinel 5 Pro was built to cover those gaps. One device, plugged into one outlet.

    Five things, one screen, updating every 2 seconds

    Your ceiling detector shows you a green light. The Sentinel 5 Pro shows you the actual numbers, so you know what's in your air instead of hoping.

    Why a wall plug beats a ceiling disc

    No battery to die at 3 AM. It runs on constant wall power (any standard US outlet, 110-240V). A built-in backup battery keeps it running up to 24 hours if the power goes out. No 9-volt. No chirp at 3 in the morning. No ladder.

    Placed where the danger is. It sits at outlet height, down low, right where heavy gases collect. Not 8 feet up where your ceiling detector can't reach the leak until the room is already full.

    A screen you can read. A blinking green light tells you nothing. The Sentinel 5 Pro shows you actual numbers, so you know what's in your air instead of hoping. The display rotates to fit your outlet and the brightness adjusts for day or night.

    Plug and play. It auto-calibrates in about 60 seconds. No tools. No drilling. No electrician. Plug it in and it's working.

    Tested to Recognized Safety Standards

    The Sentinel 5 Pro is tested against the same safety standards that govern the detectors sold in stores. Not marketing badges. The real ones.

    CE β€” Meets the applicable European Union product safety requirements.

    UL 217 β€” The U.S. safety standard for smoke alarms.

    UL 2034 β€” The U.S. safety standard for carbon monoxide alarms.

    EN 50291 β€” The European safety standard for carbon monoxide detection in the home.

    Each unit is tested to these standards before it ships. Full test reports are available on request.

    WHY THIS BEATS YOUR OLD ALARM

    Don't settle for outdated technology. See the difference.

    Sentinel 5 Pro

    • Rechargeable, no cold-chirp
    • Live numbers, the moment levels change
    • Outlet height β€” where heavy gases collect
    • Plug in. 30 seconds.

    Old hardwired / 9V alarm

    • Dies in the cold, chirps at 3 AM
    • A blind green light, then a scream
    • Ladder, wiring, sometimes an electrician
    • Usually one (smoke or CO)
     
     

    Sleep Through the Night for 90 Days β€” or Your Money Back

    Some families feel the relief the first night. Others take a week to stop checking the old alarm out of habit. Either way: live with Sentinel for 90 days. If you don't finally rest easy knowing your family is protected, return it for a full refund. We'll carry the risk so you don't have to.

      FAQs

      Yes. Unlike standard plug-in alarms that fail the moment the grid goes down, the Sentinel 5 features a built-in 2000mAh Lithium-Ion backup battery. It provides up to 24 hours of continuous, high-precision monitoring during storms, blackouts, or emergencies. You are most vulnerable in the darkβ€”we make sure you’re never unprotected.

      Plug it in at a standard outlet. Because CO and gas are heavy and sink, outlet height actually catches them better than a ceiling mount does.

      No tools, no ladder, no electrician. Plug it in β€” about 30 seconds.

      Both, plus smoke, temperature, humidity, and air quality β€” five in one.

      Absolutely. Because of the internal battery and magnetic mount, many of our customers use the Sentinel 5 as a portable safety shield for RVs, campers, or hotel rooms where maintenance standards might be unknown.

      You have 90 days to return it for a full refund. No risk.
