What is an IR Camera on a Laptop?

An IR (short for ‘infrared’) camera is a special laptop camera that uses infrared light to take pictures or videos in low-light conditions. Many laptops have such built-in cameras, which can be used for Skype calls or taking pictures in dimly lit rooms. If your laptop doesn’t have one such camera, you can usually buy one as an external accessory. Here’s a closer look at how they work and what you can do with them.

How Do They Work?

Infrared (IR) cameras work by emitting infrared light and then using a filter to see the reflected images. This makes them ideal for taking pictures or videos in low-light conditions since regular webcams rely on visible light, which doesn’t work well in dark environments. New IR cameras coming to the market, can also be used for facial recognition and tracking to capture details that aren’t visible to the human eye.

Uses Of IR Cameras

Such cameras are most commonly used in low-light conditions or for taking pictures/videos in dark environments. However, their applications don’t stop there. Below are common IR capabilities.

Facial Recognition

One of the most common uses for Infrared cameras is facial recognition. This technology is used in everything from smartphones to security systems. The camera app captures infrared light reflecting off your face, which is then converted into a three-dimensional map. This map is used to compare against other faces in a database, making it an effective way to identify people.

Thermal Imaging

IR cameras can also be used for thermal imaging. This means they can detect heat, which can be useful for various purposes. For example, firefighters use thermal imaging cameras to find people trapped in burning buildings. These cameras can also be used to find insulation leaks or diagnose electrical equipment problems.

Skype Calls

Another common use for IR cameras is Skype calls. Many laptops have such built-in cameras, which can be used for things like video chatting and taking pictures in low-light conditions. If your laptop doesn’t have an Infrared camera, you can usually buy one as an external accessory.

Clean the lens regularly.

Like all cameras, IR cameras need to have their lenses cleaned regularly. dirt and dust can build up on the lens and cause the image to be blurry.

Avoid using the camera in direct sunlight.

Direct sunlight can damage the sensor in an Infrared camera. If you’re using the camera in sunlight, shield it from the sun with a hat or umbrella.

Keep the camera away from heat sources.
