You’ll start paying more for temperature measurements of 500º Fahrenheit and higher. Temperature range: If you need a thermal camera that can measure high temperatures accurately, you’re going to pay more. Screen quality: Larger and sharper display screens drive up the price of the thermal camera quickly. Resolution: Cameras that can precisely measure the scene and create the most detailed images cost more. The cost differences among thermal cameras often depend on these factors. Mid-range models run from $500 to $2,000, while the priciest thermal cameras can cost anywhere from $2,000 to $10,000. The least expensive thermal cameras will cost roughly $200 to $500. You can end up spending a lot on a thermal camera, especially if you have specific high-end needs. If you’re just looking for a draft around a door or window, a low resolution camera may be enough. These cameras give you a general idea about temperature differences that exist in the scene, but the images are not sharp. Lower resolution small screens are found on inexpensive units. This makes it easier to identify shapes you’re seeing on the screen or to pinpoint the source of a problem. Larger screens with high amounts of resolution allow you to receive a clear picture of the scene. The resolution of a thermal camera’s display screen can play an important role in your enjoyment of the system. Advanced thermal cameras may even allow you to set an alert when any part of the scene exceeds a certain temperature. This feature can help you determine if a certain part in a device is overheating regularly. They then can provide you with the high, low, and average temperatures of different objects in the scene over a set period of time.
But more advanced models may take continuous measurements of a scene, storing the data. Some thermal cameras are simple units that only measure the current heat signature of objects. You then can view the thermal image directly on the mobile device’s screen. This allows the unit to have a larger and sharper display screen.Īnother popular option is a thermal camera that attaches to a smartphone or a tablet’s input port. Some thermal cameras have a design more like a smartphone. It’s displayed on a screen at the back of the camera. You hold the handle and pull a trigger to start recording the image. Many thermal camera bodies are similar to the handle part of a cordless drill with the camera at the top. Thermal cameras don’t really look like visible light cameras, such as a DSLR. But there are some key differences that will help you find the perfect model for your needs. Thermal cameras have a few features that are common on every model. This method provides exact measurements, data tracking, and locations of items in the scene.

For example, if you’re trying to find a leak around a window, the thermal camera simply shows you the approximate location.įor more complex needs, some high-end cameras will save their data, allowing you to run it through software later. You won’t see clear facial features or the color of their clothing, but the person’s outline will be visible and easily identifiable.įor simple thermal cameras, the image is shown on the screen for immediate consideration. If a person is in the scene, the camera will create a picture that resembles a silhouette of the individual. Through these temperature differences, the camera’s software is able to create an image on the screen.
This allows it to measure temperature differences. Instead of an image sensor that measures visible light, as is found in a standard camera, the thermal camera uses an infrared image sensor. It then displays an image on a screen that shows the difference between the thermal energy all objects in the scene are emitting.
Thermal cameras 101Ī thermal imaging camera measures the thermal heat of a person or an object in the area. Thermal imaging is a useful tool when trying to view objects during night time, when visible light is limited or not available.
