Your phone already has everything you need
The idea that someone could be recording you in a hotel or vacation rental is disturbing. Although it is not common, it happens. And the worst thing is that many of these devices are designed to go unnoticed.
But here’s the trick: your cell phone can see what your eyes can’t.
Three methods that really work
First, the camera. Turn off all the lights, close curtains and open the camera app. Many recording devices use infrared light to film in the dark—invisible to us, but not to the phone’s sensors.
Visit strategic points: smoke detectors, plugs, clocks, mirrors. If you see little bright spots where nothing should be… that’s your first sign.
“If you see small bright spots or flashes that cannot be seen with the naked eye, they could correspond to a hidden infrared camera”
Second method: the flashlight and the reflection. Turn off the lights, turn on the flashlight, and point it at suspicious objects while looking through the camera. Camera lenses reflect light in a particular way—a small but bright flash.
It works best on phones with good sensors, but with patience you can try it on almost any device.
Third: Scan the WiFi network. Many modern devices connect to the internet for streaming. Apps like Fing or Network Scanner show everything connected to the network.
Connect to the location’s WiFi and check if generic names such as “IP Camera” or “Webcam” appear. It is not definitive proof, but it is a warning to investigate further.
Two additional tricks (lesser known)
Interference in calls. Some cameras emit signals that interfere with your phone. Make a call and walk around the room—if you hear strange noises in specific areas, check those spots.
And basic visual inspection: objects that point directly to the bed or bathroom. Alarm clocks, chargers, decorative stuffed animals. Look for small holes or illogical locations.
For mirrors: finger test. Place a finger on the glass; If there is no space between your finger and its reflection, it could be a two-way mirror.
If you find something…
Do not touch anything. Document with photos, inform the administration immediately and request a room change. If you don’t get an adequate response, report it to authorities—recording without consent violates your privacy.
In public spaces, first check if it is part of authorized security.
Most importantly: this takes minutes. You arrive at the hotel, do the quick check-in and that’s it—tranquility guaranteed during your stay.
