How to find hidden cameras

I can teach you a simple and efficient method, which is to use a thermal imager to find hidden cameras.

Electronic equipment generates heat when working. The thermal imaging camera can quickly search for suspicious temperatures in the hotel. Insert the thermal imaging camera module into the mobile phone, open the APP, and you can view the thermal imaging screen, arm the mobile phone into a thermal imaging camera, and conduct temperature detection of sensitive places such as toilets, bathrooms, air conditioners, bedside tables, etc. Usually hidden cameras will be recording for a long time. If placed in a hidden location, ventilation and heat dissipation are poor, and a large amount of heat generated during operation will accumulate. In the thermal imaging camera screen, the hidden camera will display red and yellow high-temperature images, which are in great contrast with the normal temperature background, as shown in the figure below. The camera hidden in the doll glows horribly on the screen of a mobile phone equipped with a thermal imaging camera module.

Example picture of using a thermal imaging camera to view hidden cameras in a hotel. Compared with the traditional methods on the market such as signal detectors, flashlight illumination, and mobile phone built-in cameras to see reflections, the thermal imaging module plugged into a mobile phone is more efficient in finding hidden cameras. High, you can buy one and try it yourself. The thermal imaging camera can also be used in scenes such as walking at night, looking for pets, measuring human body temperature, etc. It is a multi-purpose camera and is suitable for people who often travel for business and stay in hotels.
