Fever Patrol: Reviewing the Digital Infrared Thermometer Research

Fever Patrol is a no-touch digital thermometer which uses patented medical-grade infrared detection technology to provide accurate temperature readings via a non-contact method and inlet sensor.


Fever Patrol is a no-touch infrared thermometer that takes accurate readings on a digital display without spreading germs.

The digital thermoeter device has been heavily promoted online in recent weeks as the COVID-19 coronavirus pandemic continues to sweep the world. Fever is one of the first symptoms of the virus, and Fever Patrol can help you detect a fever early.

Fever Patrol claims to be fast, safe, and “100% accurate” at detecting fevers. The device is primarily marketed towards parents who want to easily check their child’s body temperature, although anyone could use it to effectively check their temperature with ease.

You can also use Fever Patrol for other purposes: you can use it to check the temperature of food or bath water, for example.

What is Fever Patrol?

Fever Patrol is an infrared thermometer that can take anyone’s temperature with no contact required.

You point the device at your child’s head (or your own), then get a non-contact temperature reading.

The makers of Fever Patrol claim their device is “faster, safer, and more accurate than traditional thermometers.” Because it uses a non-contact design, temperature readings are more accurate than many contact temperature reading devices. Additionally, no-contact readers can help persuade children who are afraid of contact thermometers to get their temperature read.

The manufacturer also claims that normal thermometers “take up to 3 minutes to work”. Fever Patrol is not just non-invasive; it also provides “100% accurate results in under a second.”

How Does Fever Patrol Work?

Hold the device above your child’s head and the infrared sensor will automatically detect your child’s temperature.

Fever Patrol is shaped like a gun. There’s even a trigger you pull when taking the temperature.

The device has enough memory to store 64 previous temperatures, letting you easily monitor a child’s health over time, comparing new temperatures to previous temperatures. You can also track the temperatures of multiple children.

Step 1) Select Body or Object mode (whether you’re measuring your child or an object)

Step 2) Hold the infrared sensor above the target, then hold down the trigger button

Step 3) In less than a second, the digital display will bring up the temperature reading and display a color code for that reading

Step 4) Wait and repeat; store up to 64 temperature readings to track the progress of a child’s fever

Fever Patrol Features and Benefits

The makers of Fever Patrol advertise all of the following features and benefits:

  • No touch technology that guarantees reliable readings without spreading germs
  • “100% accuracy”
  • Color alarm that instantly alerts you if your child is running a normal body temperature, mild fever, or high fever
  • Check the temperature of anything, including rooms, bath water, food, baby formula, and household objects
  • Take temperature without waking up your child
  • Avoid spreading bugs and germs between multiple children with contact thermometers

The “100% accuracy” claim is unusual. Fever Patrol claims that their device is “accurate up to 0.4°F (0.2°C)”, yet they also claim their device is 100% accurate. These seem like two contradicting claims. Even a small temperature difference can have a big impact on how a fever is treated.

How Do Infrared Thermometers Work?

Infrared thermometers use a technology called black body radiation to detect the temperature of an object.

Any object with a temperature above absolute zero has molecules inside of it moving around. When temperature rises, these molecules move faster and faster. As they move, the molecules emit infrared radiation, which is a type of electromagnetic radiation below the visible spectrum of light. Hotter molecules emit more infrared light. When molecules move quickly enough, they even start to emit visible light (which is why heated metal and other objects can glow red or white).

An infrared thermometer simply detects and measures this radiation.

Infrared thermometers like Fever Patrol use a lens to focus infrared light from one object onto a detector (called a thermopile).

The thermopile (like your baby or bath water) absorbs the infrared radiation and turns it into heat. The more infrared energy, the hotter the thermopile gets. This heat is turned into electricity. The electricity is sent to a detector, which uses it to determine the temperature of whatever the thermometer is pointed at.

Ear thermometers are infrared thermometers. The ear is sensitive, which is why non-contact infrared technology measures the temperature of the ear without actually touching it.

Firefighters also use infrared technology to detect “hot spots” for fierce forest fires. You can also see infrared thermometers in factories, where manufacturers ensure machines are running at a normal temperature.

Today, you can find plenty of cheap infrared thermometers available online.

Frequently Asked Questions About Fever Patrol

Especially, when it comes to the temperature and health of their children, consumers are right to have a number of questions. This section will answer some of the most commonly asked questions about Fever Patrol and the company behind it?

Q: Why is it important to monitor body temperatures?

A: It is always important to have a device near you that can effectively monitor body temp, especially considering that many illnesses are first noticeable by a spike in body temperature. But with the spread of global virus COVID-19, it has never been more important to check the temperature of yourself and your children each day. Fever is one of the first signs of this virus, and catching the illness early is key.

Q: How do infrared thermometers work?

A: Infrared thermometers work to detect and measure the amount of infrared light being emitted at the thing they are measuring. When molecules heat up, they begin to move faster and create more infrared light. Infrared thermometers easily measure temperature with extreme accuracy by measuring the amount of light present in the target.

Q: Are infrared thermometers dangerous?

A: Generally, no. Some researchers claim that infrared devices can be harmful, but infrared thermometers don't produce the light; they merely measure it. So, for the most part, infrared thermometers are completely safe to use.

Q: Who should use Fever Patrol?

A: Fever Patrol was originally made to be used by parents on their children. Because traditional thermometers can scare children, Fever Patrol offers an effective and happy alternative for parents who need to measure the temperature of their children. However, the devices can be used to measure temperatures in anyone.

Fever Patrol Pricing

Fever Patrol is priced between $75 and $100 per unit, depending on how many you order. Purchasing options include:

  • 1 Thermometer: $99.99 + $8.95 Shipping
  • 2 Thermometers: $199.98 + $9.95 Shipping
  • 3 Thermometers: $224.98 + $10.95 Shipping
  • 4 Thermometers: $299.97 + $11.95 Shipping

You can pay online via PayPal or with a credit card.

Fever Patrol is priced significantly higher than competing infrared thermometers. A typical infrared thermometer costs $10 to $30. Amazon’s best-selling infrared thermometer, for example, only costs $10. It’s unclear why Fever Patrol is so much more expensive than competing infrared thermometers that have better features and build quality.

Fever Patrol Refund Policy

Final Thoughts

Fever Patrol is an infrared thermometer that claims to be 100% accurate at detecting fever in your child, although the manufacturer admits that it’s accurate with differences “up to 0.4°F (0.2°C)”.

A non-contact thermometer like Fever Patrol can help you avoid spreading germs between yourself and your child or multiple children. You can also get a temperature without waking up your child.

Fever Patrol has unusually high pricing: it’s currently sold for $75 to $100 online. Other infrared thermometers with similar (or even better) features sell for $10 to $30.

For all of these reasons, parents may want to buy a Fever Patrol infrared thermometer to track fever symptoms in their children – or themselves. However, there are plenty of cheaper infrared thermometers available online.
