Fires are among the most common domestic disaster. They also cause more severe implications than other common domestic disturbances, including bodily harm, death, and property loss. Most domestic fires happen accidentally, which is why a smart smoke detector is so important.

For example, due to a short circuit in household appliances or a cooking session gone wrong. However, it can be intentional, such as in cases of arson.

Given the disastrous consequences of fire outbreaks, it is advisable to have an early warning system like a smoke detector. The device alerts homeowners of smoke and possible fires via a loud alarm, thus enabling them to rush to safety and call emergency services.

Traditional smoke detectors have a reputation for sometimes triggering false alarms and having annoying low-battery sounds. As a result, some companies have introduced smart smoke detectors to make up for the shortcomings of older smoke detectors.

Despite being better than older versions, many homeowners are unwilling to shift to them. That is why we took the initiative to highlight some reasons for switching to these smart devices. Read on for more details. 

Reason #1: Real-Time Notifications

One of the biggest shortcomings of traditional smoke detectors is that they are only helpful when someone is on the property. If a traditional smoke detector goes off when you’re at work or out running errands, you will only find out when you receive a call from your neighbors or get home to find firefighters trying to put out the blaze.

On the other hand, smart smoke detectors can send notifications to your smartphone via Wi-Fi when they detect smoke in your house. Such alerts allow you to call someone to check what is happening and notify the fire brigade — even when there’s no one at home.

Additionally, some devices can alert first responders directly, increasing the chances of preventing significant property damage. 

Reason #2: Remote Control

The screeching sound of a smoke alarm can be extremely irritating and disorienting. That is especially true when dealing with older smoke detector models. Such devices require users to physically turn them off by pressing the reset button or removing the batteries. 

However, when you have a smart smoke detector, you do not have to worry about scampering to find something to step on to reach and silence the smoke detector. You can remotely turn off a beeping smart smoke alarm via your smartphone. This is convenient, especially during a false alarm. 

Reason #3: Reduced Risk of False Alarms

Traditional smoke detectors are often triggered by false alarm situations, including:

  • Overcooked food smoking up the kitchen
  • High humidity conditions
  • Dust collection within the unit

Frequent false alarms can easily desensitize property owners and cause them to lower their guard, thus increasing the risk of you ignoring a genuine fire outbreak. 

Smart smoke detectors have better sensors to prevent false alarms. For example, humidity sensors limit the number of false alarms by detecting steam caused by showers. Others have sensors that differentiate between smoke from a burnt meal and hazardous fumes.

Another irritating feature in traditional smoke detectors is the low battery warning system, which produces an annoying high-pitched sound to indicate the need for a battery change. Older smoke detectors also require manual testing to determine whether the device remains functional.

A smart smoke detector will send an alert to your phone when the battery runs low. Some also have self-diagnostic mechanisms that evaluate the conditions of the smoke sensors and send notifications to your phone when they detect any flaws.

Reason #4: Precise Identification of Hazardous Zones

Older smoke detector models do not inform you of the exact location of a fire. That means you might inadvertently stumble into a room engulfed in flames when trying to escape, preventing a safe exit. 

On the other hand, smart smoke detectors are excellent at informing homeowners of the precise location of a fire. A smart system will identify which detector triggered the alarm and notify you to avoid the area.

This allows you to find safe passageways out of the house without inhaling smoke or passing by burning objects.

Reason #5: Integration with Smart Home Systems

Smart home devices make domestic living more convenient and comfortable by handling mundane tasks. For example, smart lighting systems automatically turn on when you enter a room and turn off when you leave, which conserves energy and lowers your utility bills.

Smart smoke detectors can be connected to other smart devices in the home to make your life easier and increase the home’s security. For instance, they can notify an automated HVAC system to shut off a property’s ventilation to prevent smoke from spreading.

This can increase your chances of leaving your home unscathed during a fire and delay the spread of the fire long enough for first responders to arrive and put it out. 

Communication between smart smoke detectors and a smart security system can ensure that all exits from a property remain open to provide escape routes for people in different building sections.

Lastly, when a fire breaks out at night, you can avoid running around in the dark by having a smart lighting system that automatically turns on the lights, allowing a safe exit from the property.

How to Choose a Smart Smoke Detector

As noted earlier, smart smoke detectors are not as popular as they should be. Therefore, most consumers looking to buy a smart smoke detector may not be familiar with the factors distinguishing one brand’s device from other competing devices.

Below is a checklist of factors that can help you buy a smart smoke detector that suits your property:

  • Price
  • Fire Detection Method
  • Notification Methods
  • Power Source
  • Range of Operation

Let’s have an in-depth look at each factor.


You can buy a smart smoke detector for as low as $40. However, the cheaper the device, the fewer smart features it will have. Therefore, even though a decent smart smoke detector can be pricey, it is advisable to purchase one that costs at least $100 to enjoy all the benefits.

Fire Detection Method

Smoke detectors work based on two mechanisms: ionization and photoelectric methods. Ionization smoke detectors contain some radioactive substance sandwiched between two electrically charged plates.

The radioactive substances allow current flow between the two plates by ionizing the air. During a fire, smoke interrupts the current flow, triggering the fire alarm.

On the other hand, photoelectric smoke detectors have a chamber containing a light source and a light sensor, whereby the light source emits a light beam towards the light sensor.

When smoke enters the chamber, it disrupts the direction of the light beam by providing a surface from which the light gets dispersed. Once the light beam gets interrupted, the smoke detector triggers the alarm.

Generally, ionization smoke detectors are better at identifying blazing hot fires, while photoelectric smoke detectors are better at spotting smoldering ones. Most smart smoke detectors have photoelectric smoke sensors, meaning when you get them, you also have to buy smoke detectors that use the ionization method to increase safety.

Alternatively, you can buy a smart smoke detector that incorporates both technologies in one device. However, such smart smoke detectors often cost more than those using only one detection method.

Notification Methods

All smart smoke detectors can send notifications to your phone. However, you should check whether the smoke detector you’ve chosen has voice alerts. 

Such alerts are beneficial to people who often panic during emergencies. For example, some smoke detectors alert occupants about which rooms are affected by the fire, cautioning them to use safer alternatives to exit the building.

Similarly, some smart smoke detectors warn occupants against returning to the affected rooms. This is especially important, as people often instinctively rush back to burning buildings in the hope of salvaging important documents or valuables. 

Lastly, people with considerable budgets can buy smart smoke detectors that can send alerts to first responders like firefighters and emergency medical teams. This feature is handy during huge fire accidents that often knock out occupants before they can exit the building or call 911.

Power Source

Smart smoke detectors can either be battery-powered or hardwired. Battery-powered smoke detectors tend to be isolated so that one alarm going off does not trigger other smoke detectors in other rooms. However, some smart smoke detectors bypass that problem through wireless connectivity. 

On the other hand, hardwired smart smoke detectors are connected to a property’s electrical grid. That means they work within an integrated system, and all sound the alarm when one goes off. 

Ultimately, battery-powered smart smoke detectors are easier to install and replace. However, hardwired smoke detectors have a better warning system and do not require regular power source replacement.

Range of Operation

The ideal smart smoke detector should be multifaceted. It should detect smoldering and blazing fires. It should also monitor and detect carbon monoxide emissions.

Carbo monoxide (CO) is a colorless and odorless gas emitted from fireplaces. Its physical properties (colorless and odorless) make it fatal as you can inhale it for several hours unknowingly.

Prolonged exposure to CO can cause unconsciousness or death in worst-case scenarios. We recommend buying a smart smoke detector that includes a CO sensor, even if it means spending a few extra bucks.


Traditional smoke detectors have been saving lives for over half a century. However, it is time for people to embrace smart smoke detectors as they are better suited to work within today’s infrastructure.

They also make life more convenient by dealing with issues like low-battery chirping sounds, which are often annoying. Overall, buying a smart smoke detector will be a valuable addition to your home’s smart system.

Frequently Asked Questions

Are smoke detectors the same as smoke alarms?

No, smoke detectors have sensors that react to smoke or fire in a room. In contrast, smoke alarms are a visual and auditory warning system that alerts people when a smoke detector senses a fire outbreak.

Are smoke detectors and fire sprinklers the same?

No, smoke detectors activate when they sense smoke or fire. On the other hand, fire sprinklers activate when they detect heat exceeding a pre-specified temperature. Fire sprinklers are installed to put out a fire before it exacerbates and spreads to other rooms.

What is the lifespan of a smart smoke detector?

By regulation, smoke detectors have a maximum lifespan of ten years, after which they must be replaced. That is because the smoke detection mechanisms deteriorate with time, thus limiting their effectiveness.

Why are smoke detectors important?

Smoke detectors act as an early warning system that helps people exit the affected rooms or buildings during fire hazards. Some smoke detectors also alert first responders, allowing timely interventions; this reduces the magnitude of damage to life and property.

What are the different types of smoke detection methods?

Manufacturers often equip their smart smoke detectors with either of two smoke detection mechanisms. Ionization smoke detectors rely on the disruption of an electric current to detect a fire.

In contrast, photoelectric smoke detectors rely on the dispersal of a light beam to detect smoke. Premium models combine both mechanisms for a more vigilant smoke detector system.
