Why Carbon Monoxide Detectors Deserve a Spot in Every Home Security Plan

Carbon monoxide is often called the "invisible killer" for good reason. It has no smell, no color, and no taste, which means the only real warning most families get is from a properly working detector. CNET recently published a guide reviewing the best carbon monoxide detectors on the market, and it is a timely reminder that CO safety deserves the same attention homeowners give to break-in protection.
At MFPGSecurity, an ADT Authorized Dealer, we spend most of our time talking about cameras, door sensors, and monitored alarms. But a complete home security plan also protects against the threats you cannot see, and carbon monoxide is one of the most dangerous of all.
What CNET's Roundup Found
Without repeating every detail of their testing, the general takeaways from CNET's review line up with what safety experts have said for years:
- Plug-in and battery-powered units both work well, as long as they meet UL safety standards and are placed correctly.
- Digital displays that show real-time CO levels tend to be more useful than simple alarm-only models, since they can flag a slow leak before it becomes dangerous.
- Smart, connected detectors that send phone alerts are increasingly popular, especially for homeowners who travel or have a second property.
- Battery backup matters, since power outages and gas leaks can happen at the same time, particularly during storms.

Why This Matters Beyond a Single Device
A standalone CO detector is better than nothing, but it has one big limitation: if you are not home, or you are asleep and do not hear the alarm, it cannot help you. This is where monitored home security comes in.
When a carbon monoxide detector is integrated into a professionally monitored system, an alert does not just sound a local alarm. It notifies a monitoring center that can attempt to reach you and, if needed, dispatch emergency responders, day or night. That extra layer matters most in the middle of the night, when CO poisoning symptoms like dizziness and confusion can prevent someone from acting on their own.
This is one of the reasons we encourage homeowners exploring a new security setup to think beyond cameras and door locks. A well-designed smart home security system can pair smoke, heat, and CO sensors with 24/7 monitoring, so the response happens automatically rather than depending on someone hearing a beep at 3 a.m.
Practical Placement Tips
Regardless of which detector you choose, a few placement basics apply:
- Install a CO detector on every level of the home, including basements.
- Place one near sleeping areas, since detection during sleep is critical.
- Avoid placing detectors directly next to fuel-burning appliances, which can cause false readings.
- Test units monthly and replace batteries or the entire unit per manufacturer guidance, since CO sensors do have a limited lifespan.
Where MFPGSecurity Fits In
We are not in the business of ranking individual retail gadgets. What we focus on is helping homeowners build a security plan around ADT's monitoring backbone, one that can include life-safety sensors like carbon monoxide and smoke detection alongside cameras and intrusion alarms. If you already have a favorite detector from a guide like CNET's, we can often help you connect similar sensor types into a monitored system so an alert actually triggers a response.

Frequently Asked Questions
Do I need a separate carbon monoxide detector if I already have smoke detectors?
Yes. Smoke detectors and carbon monoxide detectors sense different things. Some combo units detect both, but a dedicated CO sensor or combo device is necessary since standard smoke alarms do not reliably detect carbon monoxide.
Can carbon monoxide detectors be connected to a monitored security system?
In many cases yes. Many smart CO detectors and sensors can be integrated with a professionally monitored home security system so that an alert notifies a monitoring center, not just a local alarm in the house.
How often should carbon monoxide detectors be replaced?
Most CO detectors have a sensor lifespan of five to seven years, depending on the manufacturer. Check the specific unit's documentation and replace it according to that schedule even if it still appears to work.
Where is the best place to install a carbon monoxide detector?
Install one on every level of your home, especially near sleeping areas and basements. Avoid placing them directly beside fuel-burning appliances like stoves or furnaces to reduce false alarms.
