It is not a crazy idea checking our environment for hidden cameras or microphones.
Surveillance sets are getting cheaper and easier to use and people are worried of Big Brother invading their privacy after cameras/microphones have been found in airbnb rentals, public bathrooms and gym locker rooms.
Companies are spending billions on surveillance (4 billion of dollars by 2023, according to the technology market research firm Strategy Analitics) and microdevices can be stashed in hard-to-spot places like clocks or water bottles.
Everybody can do a basic inspection of the environment like turning off the lights and, with the use of a flashlight, see if the lens of a camera shines back. Other, but expensive, method could be buying radio frequency detectors that can pick up signals emitted by these devices.
