I Used This Phone Add-On to Find Hidden Cameras, Leaks and More in My Home

A new thermal imaging add-on for smartphones, the Thermal Master P3, has made it easier for individuals to detect hidden cameras, insulation issues, and water leaks in their homes. Priced at $300, this compact device is a fraction of the cost of a professional home inspection and can be used across multiple seasons and trips.

The Thermal Master P3 boasts a sleek metal framework and a compact carrying case that can easily fit into a pocket. Capable of detecting temperatures ranging from -4 to 1,112 degrees Fahrenheit with an accuracy of plus/minus 3.6 degrees, this device pairs with a free app that provides users with a variety of settings to adjust for their specific needs.

Using the P3, users can detect hidden cameras, such as those found in vacation rentals, insulation problems, and water leaks. One account from the author found the thermal camera effective in uncovering both wired and wireless cameras in their home. The wireless camera, for instance, was detected in an area where it wasn't emitting much heat while in standby mode.

Additionally, the P3 can identify spots with inadequate insulation, like drafty windows or poorly insulated walls, and may even reveal water leaks. By examining temperature variations, the device can help users pinpoint potential issues that, if addressed, could lead to significant energy savings or even prevent costly repairs.
