How thermal imaging works

We have already discussed the mechanism of thermal imaging in detail in our previous articles. Here’s a quick look at how a Flir home security system based on thermal imaging works.

To start with, any heat or thermal radiation results in the emission of infrared radiation. Now, infrared radiation is an integral part of the electromagnetic spectrum. It lies just below the frequency of red visible light. 

Here’s something interesting- even cold objects like blocks of ice emit some amount of infrared radiation.

In a thermal imaging camera, a lens focuses the infrared light over an infrared detector. It is then sent to an electronic sensor where the data is converted into an image. 

The thermal sensors are highly sensitive and can detect temperature differences as small as 0.01°C.

Finally, the image is visible on the screen or a viewfinder. The sensor resolution can vary and the image can range between 80 x 60 to 1280 x 1024 pixels. 

Point to be noted- thermal sensors need to detect wavelengths that are larger than visible light. That makes the sensor elements larger in size. So thermal cameras usually have fewer pixels than normal cameras of the same size.

The Advantages of Thermal Security Cameras

When you’re looking for a 24/7 monitoring solution for your home, a combination of multiple Flir thermal imaging cameras is a great option. So let’s take a look at some of the major advantages of a Flir security system using thermal cameras.

  1. For the perimeter protection of a property, there might be outdoor conditions where no or limited light is available. Thermal cameras are an ideal choice for such cases. 
  2. The advantage of a thermal camera is, it can detect any irregularities in the heat flow inside a room or a building. So you get better safety when it comes to fire hazards. Moreover, it allows you to detect potential issues related to air leakage or electrical faults.
  3. You don’t need to arrange for separate artificial illumination to keep your cameras functioning at night. Now that can result in significant cost savings.
  4. The thermal cameras come with a wider imaging range that reduces the need for installing more cameras and mounting poles. They also need much less maintenance than ordinary cameras.
  5. A normal security camera can trigger false alarms due to wind, rain, insects, or tree branches. But thermal imaging cameras eliminate these issues to deliver a more accurate intrusion detection system.
  6. One big advantage of a Flir thermal security camera is that it can deliver high-contrast images in all light conditions. It’s a smart choice for detecting persons or objects in places where they shouldn’t be. The technology is also effective for detecting a person hiding behind bushes or in a shadow.
  7. In case you already have a video surveillance system in your home, a thermal camera is a great way to upgrade the system. They can also be integrated with all major surveillance systems.
  8. It may happen that a normal camera gets blinded by bright light, fog, or heavy rain. Such scenarios can be avoided by the use of thermal cameras.

Important Things to Know Before Choosing a Flir Home Security Camera

Choosing a Flir Home Security Camera

Here are a few technical features that you should know about before picking a Flir security system.

Microbolometer

A microbolometer sensor is the most commonly used infrared detector in any Flir thermal security camera. In most cases, they are built from processes involving vanadium oxide (VOx) or amorphous silicon (a-Si).

A typical microbolometer is made from an array of small sensors that detect heat signals ranging between 7 to 14µm in wavelength. Basically, when an infrared wave strikes a sensor element, some heat is generated. This causes a change in electrical resistance. This variation is converted into temperature values and then into a graphical image.

These units are smaller in size and lighter in weight. As a result, power consumption is reduced, making a device more cost-effective.

Thermal Pixel Pitch

The Microbolometer pixels come in a complex shape. Pixel pitch refers to the center-distance between two pixels. It is measured in microns (µm). Most manufacturers, including Flir use 17 μm pixel-pitch arrays in their devices.

Spectral range

The spectral range refers to the range of wavelengths that the camera sensor can detect. The Flir optical gas detection cameras have a spectral range between 2µm to 5µm. So they are termed mid-wave cameras.

On the other hand, the spectral range of thermal cameras is between 8µm to 14µm. So they are long-wave cameras, more suited for activities like electrical inspection and firefighting.

Cooled and uncooled thermal detectors

This is one aspect that you will notice in the specifications of every Flir thermal security camera system. Cooled thermal detectors require additional equipment to operate in extreme temperatures. In addition, the cooling equipment is bulky and expensive. Also, it requires a significant cooling-down time after use.

Naturally, uncooled thermal sensor technology is the preferred choice for lightweight and portable devices. This makes them useful in the production of affordable thermal imaging applications. Actually, uncooled sensors less sensitive than cooled thermal sensors. But they are a practical choice for commercial applications.

Field of View (FOV)

This is the extent of a view that the camera lens can capture at any given moment. Lenses with a wide-angle FOV are needed when you need to view closer objects. This can range from 45° to even higher values. 

To view distant objects a telephoto lens is needed. These can have a FOV between 12° to 6°. Many cameras come with multiple lenses that make them highly versatile.

IR Resolution

Resolution is more important in the case of thermal imaging than that of digital imaging. That’s because it affects the accuracy of temperature measurement.

The resolution depends on the number of pixels in the camera. With a higher number of pixels, the camera can capture better details with more visual resolution. This results in a more accurate measurement of temperature variations. With a high resolution, the camera can function from a larger distance from the object without losing accuracy.

Thermal Security Camera Buying Guide

Thermal Security Camera Buying Guide

As you can see, thermal security cameras offer a range of security features. But here’s the thing…

Different thermal security cameras are designed for different purposes. While some of them are used for home security, others are for specific functions. These include plumbing, electrical works, firefighting, hunting, and others.

Most importantly, you need a device that offers quality and dependability and suits your purpose of use.

So before you get lost in the vast range of options, here are a few points that you need to keep in mind.

Resolution

Obviously, a security camera that delivers blurry images is practically useless. So make sure that the camera comes with the right sensor resolution that delivers sharp images even in darkness. 

Apart from the resolution of the thermal sensor, the optical camera should also come with full HD resolution. Ideally, you should buy a camera with the highest resolution that your budget allows.

Motion detection

This is a useful feature that starts recording only when motion is detected. Sounds convenient? Not exactly.

In many cameras, motion detection can raise false alarms in case of animal or foliage movement. However, the Flir security camera software comes with the right analytics that can detect motion accurately. This makes them a hassle-free choice for outdoor use.

Accuracy

The reliability of an infrared camera also depends on accuracy. Ideally, the device should meet or exceed ± 2% accuracy levels.  The results should also be consistent over a period of time. Flir security cameras also allow you to input parameters like  “emissivity” and “reflected temperature” for better accuracy.

Durability

A durable outdoor camera can not only withstand harsh climates but also need less maintenance. This includes water and dust proofing, along with resistance to extreme temperature variations and humidity. The Ingress Protection (IP) rating is an important factor in this regard.

Field of View

As already mentioned, the field of view of a camera can vary depending on the lens type. If you want to keep an eye on a large room or a wide area, a large field of view is needed. If you just need to monitor a narrow area like the main entry or a passage, a narrow field of view is good enough

Temperature Sensitivity

The temperature range and sensitivity of the thermal imager should be wide enough to capture a broad range of temperatures. In addition, make sure that it has a high sensitivity. This allows the camera to capture even the smallest temperature differences on a surface.

Two-way Audio

A camera with two-way audio allows you to hear in addition to delivering an image. So you get a clearer idea of the overall situation. In addition, you can also hear what is going on beyond the visual range of the camera. 

But that’s not all.

This feature also allows you to speak through the camera. This is an effective way of dealing with an intruder in your home from a safe distance.

Conclusion

So let’s sum it up.

Undoubtedly, Flir is one of the top brands in this field. Flir security camera systems are one of the best options to provide complete security to a wide range of environments. From affordable design to highly specialized cameras, there are a lot of choices for home security.
