Traveling to new places is exciting, but concerns about privacy, especially the presence of hidden cameras in hotel rooms, have become more common. These invasions can compromise your safety, but thankfully, your smartphone can help detect such threats.

Here are four effective ways to use your mobile device to spot hidden cameras and ensure a worry-free stay:

1. Use Your Flashlight

Hidden camera lenses often reflect light, so turn off the room lights and use your phone's flashlight to scan areas like smoke detectors, air vents, alarm clocks, or mirrors. Look for any reflective surfaces or small glints that could indicate a camera lens.

2. Detect Infrared Lights

Most hidden cameras emit infrared (IR) light, invisible to the naked eye but detectable through your phone's camera. Turn off the room lights, open your camera app, and slowly pan across the room. Watch for small, pulsing dots or glows, which could signal the presence of an IR camera.

3. Use Camera-Detection Apps

Various apps available for Android and iOS can help identify hidden cameras. These apps utilize your phone's sensors to scan for infrared light, magnetic fields, or unusual signals that may indicate a camera.

4. Check the Wi-Fi Network

Many hidden cameras use Wi-Fi to transmit footage. Open your phone's Wi-Fi settings and look for unfamiliar devices like "IP Camera" or anything suspicious. You can also use Bluetooth to detect any unknown connections.

These simple steps will help ensure your privacy while traveling.
