See beyond what meets the eye and explore thermal landscapes with the P2 Pro Thermal Camera.
In a world where technology continues to push the boundaries of innovation, the concept of an infrared thermometer camera may seem like something out of a sci-fi movie. However, this cutting-edge device has become an indispensable tool in various industries, offering a multitude of benefits that were once unimaginable. From detecting hidden electrical faults to identifying thermal leaks in buildings, an infrared thermometer camera provides a unique and invaluable perspective by capturing images based on temperature variations rather than visible light.
Today, infrared thermometer cameras come in a variety of shapes and sizes. My favorites are the ones that connect directly to my phone and work in tandem with an app. I recently had the option to test out the P2 Pro Xinfrared Thermal Camera for Smartphones by InfiRay. It’s small and exceptionally accurate with temperature readings.

User Experience
The box for the P2 Pro camera is nearly all black with “InfiRay P2 Pro” printed in gold on the front. The phrase “touch the temperature of the world” is printed in English and Chinese on two sides of the box and basic product information (name, model, etc.) is included on the back. It’s a very plain box with only the essential information included.

I was surprised to find very little when I opened the box. There is a small folder with some print materials included and beneath that is the camera and the Macro lens adapter. The majority of the box was filled with foam inserts that had cutouts for the camera. I feel that the company could probably shrink the size of the box and still have plenty of room for all the materials included.
Getting started with the P2 Pro camera is very, very simple. First you download the app for your device. The user manual instructs you to search for “P2 Pro” in your app store, but that did not return the correct apps for me. I did a second search for “InfiRay” and the correct app “Thermal P2” was one of the options. That is the correct app to use.

After the app is downloaded, you simply plug the camera into the Lightning port an wait for it to initialize. Something to note here – all the pictures in the instruction manual show the camera facing the same direction as the screen of your phone. That doesn’t really make sense because you wouldn’t be able to monitor what you were doing while using the camera.
When it does initialize, the thermal image will be returned on the screen of your phone. this is the basic mode that most people would want to use. There is a “Professional Thermometry” option that provides users with the chance to do things like look at a range of temperature between two points or select an area within the camera view and have a range of temperatures returned. This is a pretty nice feature if you need to have more advanced data like that.
By default, the temperature unit is set to ‘Celcius’ but you can change this within the Settings menu > Measurement Setting. Users also have the ability to view the thermal image in a variety of color palettes.


When it came to testing, I decided to take some images of my dog while he was asleep in his favorite chair. The location of the chair happens to be next to an air vent and our air conditioner was currently running. So, I knew I would get an interesting range of temperatures. Using the basic mode, I snapped a few shots making sure to keep the dog and the vent in the frame. Then I used a separate digital infrared thermometer to see how accurate the temperatures were. The dog’s temperature was about 1-degree difference between the two thermometers while the air vent was exactly the same.
Images are saved to the app and not the phone’s photo library. This was something I wasn’t a big fan of because I find it easier to locate images if they are all stored in the same place. It would be great if a software update to the app could offer this as an option within settings for users who want to have the flexibility of where to store their captured images and video.
Pros
- Very easy to use – essentially plug ‘n’ play.
- Readings seem to be accurate.
- It does not have to be charged.
Cons
- The packaging seems like too much for such a small product.
- The instructions direct users to the wrong app. “Thermal P2” is the correct one for iOS users.
- The carrying pouch was a little too small to store the camera in safely.
- Thermal images are saved within the app – not to the Photos app.
