All You Need to Know About Thermal Imaging

A Camera Like No Other

By Black Hills Thermal Imaging - Own work, CC BY-SA 3.0,

A thermal imaging camera is also called an infrared camera, thermographic camera, or a thermal imager. It is a camera that creates an image using radiation from infrared. It forms an image using visible light. These types of cameras are sensitive to wavelength from about 1,000 nanometers to about 14,000 nanometers.

These are different from your usual cameras because normal cameras work on a different system than the thermal imaging cameras. Some cameras cannot take photos in specific lighting conditions (e.g. too dark or too bright setups), and some might not work in different weather conditions.

Cameras That Can See Through Fire and at Night (and More)

Thermal imaging cameras were originally developed for military use during the Korean War. Nowadays, it is used by a lot of people in different fields.

For instance, it is used by firefighters to see through smoke and find people in burning buildings or houses. It is also used to localize hotspots of fires. 

Power line maintenance technicians also use these cameras to locate overheating joints and parts. They do this to eliminate potential safety hazards in buildings and establishments.

It is also used by building construction technicians to see heat leaks that will help in improving air conditioning in a building or in a house.

Thermal imaging cameras are also used to detect fever in humans too. That’s why we can always see these cameras installed in airports, to check if arriving passengers are sick. They use it to detect infection from the incoming passengers.

Recently, it has proven useful during the COVID-19 pandemic in airports around the world, to identify people who are suffering from the virus based on their thermal images in these cameras.

A lot of fields use thermal imaging cameras for different reasons, which explains how useful these cameras can be when installed in your houses.

Pros and Cons of Thermal Imaging Cameras

Pro: Can Take Clearer Pictures Like No Other

One of the best qualities of thermal imaging cameras is the ability to capture the best images possible. Thermal cameras can see what the naked eye cannot see. They provide visual clarity in the most challenging conditions.

Security cameras need to capture quality images. With that in mind, thermal cameras can take clear pictures and imagery regardless of lighting conditions.

In terms of using it as security cameras, these cameras can perfectly capture intruders lurking in the perimeters of your yard and you can be alerted immediately should they try to enter your property with as much accuracy as you can expect.

Pro: More Accurate Products and Lesser Worries

These cameras are also known to be beasts in camera technology. Thermal imaging cameras are immune to visual limitations.

What this means is that, regardless of how bright or dark the area is, the thermal camera can still capture high quality images. It also helps in having fewer false alarms since it works on detecting heat radiation. 

Capturing accurate images means more security for you and your family. It also means that it can give a higher return on the investment. These cameras can also take photos and videos regardless of weather conditions.

No need to worry if it’s raining outside too hard, because thermal imaging cameras can still manage to capture high quality shots.

Con: Expensive and Can Potentially Cause Lawsuits

On the other hand, thermal imaging cameras are expensive. Not all houses and businesses have it because of its price. Airports and hospitals usually have it rather than simple homes and offices.

They can be a bit pricey compared to normal CCTVs. Cheaper cameras worth $52.99 can be found on Amazon, but the quality might be a bit compromised. 

If you’re willing to spend more money for these cameras, there are high quality thermal imaging security cameras worth at least $164 each. Prepare at least $660 if you want to put these on four corners of the house.

Using these cameras can also cause potential lawsuits. The Fourth Amendment protects the people from unreasonable searches and seizures from the government. Since thermal imaging cameras are considered to be too advanced to use in residential areas by some people, they might feel that their privacy is being compromised in exchange for your protection.

Similar cases from 2001 (Kyllo vs. USA) proved that the use of thermal imaging cameras can capture images that might feel invasive in other peoples’ point of view.

Using thermal imaging cameras can also potentially expose you to cameras in an unnecessary manner. The cameras can tell things an average person would not be able to tell if he’s standing outside the house.

For example: it can show those looking at it when people usually go to the bathroom, do some private things in their houses, and other personal stuff.

If you are considering using this in a tight neighborhood, better think twice before having trouble with your neighbors. Make sure that the cameras will be angled properly, not directly capturing anyone’s property, such as a room or a part of their house.

Talk to your neighbors first to see if they are okay with it and what arrangements can be made for both parties’ convenience and security.
