InfiRay P2 Pro Thermal Camera (for IOS) Review: Tiny but Powerful

The Lowdown

I think the InfiRay P2 Pro thermal camera is a great product that has the advantages of compact size, lightweight, low power consumption, and high performance and offers a lot of value for its price. It is small enough to carry around in your pocket and yet powerful enough to give you clear and accurate thermal images; it is a fun and useful tool.

Overall
4.5

Pros

  • Image quality
  • Ease of use
  • Small size
  • Rugged construction

Cons

  • The App’s name should be updated in the Apple App Store
  • They should offer a connection adapter or dongle for new generations of iPads that use USB-C

The InfiRay P2 Pro thermal camera is a tiny but powerful device that connects to your smartphone and lets you see the heat signatures of objects and creatures around you. At 9g and 18mm x 27mm x 9.8mm, it is the world’s smallest thermal camera and, despite this, boasts some impressive stats. Its 256×192 pixel resolution is excellent at this price range and beats some competitors at higher prices.

The InfiRay P2 Pro has a self-developed ASIC chip and a refresh rate of 25Hz, easily outmatching similar cameras made in the United States, which need to comply with the 9Hz (EAR) Export Administration Regulations limit. The result is much smoother motion in video.

The camera plugs directly into your phone, which it uses as a screen, storage device, and battery. The unit’s low power consumption of 350mK enables it to work continuously for 6-8 hours on a fully charged iPhone.

The InfiRay P2 Pro plugs firmly into the phone with the Apple phone cover that I use but required the removal of a slightly thicker third-party protector. Third-party extension adapters are available.

The P2 Pro comes with a magnetic macro lens that can help you see finer details. Without the macro lens in place, the camera captures clear images within an effective range of 16.4 feet; with the lens in place, the working range is reduced to inches.

The macro lens comes with a lens cap, but as the camera itself does not, it is advisable to leave the macro lens in place when the unit is stored. The camera also comes with a drawstring cloth bag. As nice as the bag may be, it is very small and seems easy to lose or crush despite the camera’s solid metal construction.

I was also impressed by the sensitivity of the InfiRay P2 Pro’s camera, whose thermal imager’s enhanced temperature range of -4°F to 1122°F (-20°C to 600°C), and a sensitivity of 40mk.

The app is easy to use, allows users to change settings, and has multiple features such as 3-point temperature measurement, image capture, video recording, and sharing. It also allows users to select from nine different imaging modes, including those shown below.

A note about the app: in the accompanying product introduction, the instructions are to search for “P2 Pro” in the App Store. This search is fruitless as the app is called “Thermal P2” in the App Store. The camera works with Android 6.0 and above and iOS 11.0 and above, which makes it compatible with most smartphones.

The camera is very versatile and can be used for various purposes such as home inspections, troubleshooting of HVAC, plumbing, and heating systems, as well as the inspection of electrical systems and printed circuit boards. It is also fun and easy to use.
