How to Use Your TV Remote to Detect Hidden Cameras

Ever get the eerie feeling you're being watched in a hotel room or Airbnb? Turns out, your TV remote might be your unexpected ally. This clever hack transforms an everyday remote into a DIY hidden camera detector—seriously! Get ready to tap into your inner spy with this surprisingly simple trick.

Here’s how it works:

Many hidden cameras rely on infrared (IR) light for night vision. While IR light is invisible to the human eye, it can be picked up by your smartphone’s camera. That’s where the TV remote comes in—it also emits IR light when you press its buttons. By using your phone’s camera to view the remote in action, you can detect those invisible signals.

Try it yourself:

• Open your smartphone’s camera app (you don’t need to record—just use the viewfinder).
• Point your TV remote at the camera and press any button.
• If you see a flickering or flashing light on your screen, that’s the IR beam—proof that your phone can detect it.
• Now, turn off the lights in your room.
• Slowly scan around the room, especially near objects like smoke detectors, clocks, or air vents, while pressing your remote’s buttons.
• Watch your screen closely. If you spot any unexpected flashes, you may have uncovered a hidden camera.

A quick heads-up:

This method isn’t foolproof. Some newer surveillance devices might use tech that doesn’t rely on IR. But even so, this trick offers a fast and easy way to boost your personal privacy—especially in unfamiliar places.

So, next time you check in somewhere new, don’t just toss your bags and relax. Take a moment, grab the remote, and do a quick scan. A little vigilance can go a long way in protecting your peace of mind.
