2. Turn off the lights in your room to spot hidden night vision cameras
You can use the night vision security camera working principle to find hidden cameras in your room. Most hidden security cameras have red or green LEDs. The LEDs will blink or shine when in low-light conditions.

When in low-light conditions, the LEDs around the camera lens will turn on automatically to supplement the lighting for the cameras to produce clear night vision images. This provides an opportunity to detect any hidden cameras that support such feature.

3. Use your smartphone to locate hidden surveillance cameras
Many people ask whether they can use their smartphone to find hidden cameras, and the answer is “Yes”. There are two easy and free ways you can undertake to find hidden cameras using your iPhone or Android smartphones even without detectors.

Method 1. Make a phone call to check for hidden cameras and microphones
Step 1. Make a phone call to your friends or family.
Step 2. Walk around your room. Hidden surveillance normally would give off a special radio frequency that would interfere with your phone call signal.

If you notice that there is signal interference in a specific place or position, stop and check out that place carefully to find out whether there is a hidden security camera there.

Method 2. Use mobile apps to find hidden cameras and listening devices
Step 1. Install a “detect hidden cameras” app on your iPhone or Android mobile phones. For example, “Spy hidden camera detector” app software is a good option.
Step 2. Launch the app on your mobile phone. The detector software will display a red glow when your smartphone approaches a hidden camera. Please note that it will also glow when near other types of hardware with radio frequency.

Helpful tip: When you are traveling and stay in the hotel room, you can take a portable battery security camera with you. You can put it in your hotel room to see who entered your room without your permission. With a security camera installed in your hotel room, you can also keep an eye on your stuff.

4. Get a professional camera detector or sensor to spot hidden cctv cameras

Professional RF signal detectors or other bug detectors are quite effective to locate hidden security cameras. A lot of news has been reported that people keep finding hidden cameras in their rental Airbnb homes. If you go on business or a vacation and rent an Airbnb house, you can find the hidden cameras with the detector quickly.

How to detect hidden cameras using a detector
1. Buy a professional detector on Amazon or other online shops. The price varies greatly, ranging from several bucks to hundreds of dollars. A few options can be found here.
2. Turn on the device and do a sweep of your room to detect hidden pinhole video cameras.

Typically the detectors will beep when they detect a signal, giving you an audible indication when you near a potential camera. Please note that the RF hidden camera detector typically only picks up one kind of frequency. If the hidden security cameras and other bugs use multiple frequencies changing rapidly, the detector might not detect the presence of hidden spy cameras.

Good news is that bad guys would not install hidden cameras with complex frequent network signals, since this type of hidden spy cameras are much more expensive.

5. Check the mirrors in your room to locate any hidden spy cameras
Don’t forget to check for hidden cameras in the mirrors in the toilet, changing or trial rooms, etc. As you may know, some awful guys tend to install a hidden spy camera on the other side of a mirror that is see-through, while the other side looks the same as a normal mirror.

There’s a useful tip you can use to detect such two-way mirrors in fitting rooms, toilets, bathrooms, etc.
1. Put your fingernail on the mirror.
2. Observe the gap between your finger and the mirror. If there’s a gap between your finger and the image, it’s a real mirror. If you finger and the image touch tip to tip, there would be a hidden spy camera in the mirror.

6. Use a flashlight to find hidden cameras
A straightforward way to detect hidden cameras is using the flashlight (works best in dark conditions).
1. Turn on the flashlight and turn off the lights in your room.
2. Pan the flashlight around the room.

Go slowly and examine any suspicious positions from different angles. If you notice any reflective lights from an object, there might be a hidden camera there.
